Ok, another try with PrimeAgra
http://www.orchidboard.com/community/semi-hydroponic-culture/30173-ok-another-try-primeagra.html
Thu, 19 Nov 2009 00:26:59 GMT:hello
I thought I'd have another try with my PA.
Last time, my chids (catts) turned soooo yellow, and died. I hope and pray that won't be happening this time. I'm following the instructions on watering, so hopefully, all works out!
I potted about 15 or so in PA. From very large Catts & Phals, and smaller ones too.
Any hints and idears on how to keep that yucky yellow death away??

http://www.orchidboard.com/community/semi-hydroponic-culture/30157-choosing-homemade-s-h-pots.html
Wed, 18 Nov 2009 20:56:13 GMTI've been growing Phals and Oncidiums in S/H for a couple years now and the roots are crazy! Repotted a Sharry Baby for a demo at my orchid society meeting and had to cut the pot apart because the roots were so thick!
Anyway, I was wondering what other people's thoughts are on choosing pots for S/H. I've been mainly using anything that was clear and plastic; party cups, gatorade bottles, bottom half of 2-liter soda bottles, etc.
And with a new baby, and reading stuff about "BPA free" bottles, I was wondering if I should be more picky with what I pot in to. What kind of plastics leech out, or possibly degrade? Is this even a concern? Since the "pots" are cheap, should I just repot in to a brand new pot and call it good?
Thanks for any thoughts!

Mon, 16 Nov 2009 03:53:44 GMTHey Everybody,
I'm new to S/H but to date am loving it! the root and leaf growth is just amazing, the vigour, colour and general appearance of the seedlings is amazing.
I have about 45 Phalaenopsis seedlings growing in 100% perlite with a light gravel covering. They're seedlings and i have seen new leaf and root growth. I just went out and purchased some liquid fertiliser it's made by "Growth Technology" here in Australia and is listed as containing the following:
Now firstly is that a pretty good mix? is there anything that i should supplement it with? secondly, how much should i apply? I have a reservoir that the pots sit in and that is permanently filled. Should i go with little continously and then flush every few weeks? or should i go with a dose, allow it to sit for a few days, then flush and fill with plain water? any thoughts/advice?
Kind regards
OzPhal

This is...This is an update to an earlier thread.
This is a baby-- a Pahl violacea var. coerulea-- which is suppose to have a blue flower that is fragrant. I want this phal to be in s/h, too, but was worried I'd lose the plant since it is so small if the roots didn't respond well to the s/h. It is growing new roots but I didn't want the plant to waste at all while those new roots got under way. Sort of like a weak patient going into surgery-- you must be very careful! It was planted in a heavier, very wet sort of soil mix-- and so I figured if it when into sphag on top of s/h it will coax it to grow into the s/h. The experiment seems to be working. The original roots are growing again and are beginning to reach into the s/h.
I know plants that have grown in sphag typically transition better to s/h, my 'Pauline' is an excellent example as she not only retained all of her old roots but grew new shoots off those roots as well. However, I have a phal 'Ember' that looks (leaf type) and acts like my violacea var.-- and yet it was grown in sphag but I lost my last one (well, its still alive but hardly while in sphag in a bag) because the roots died quickly in s/h. I got a second plant and its in sphag and I'm watching it closely for rot but the roots seem to love it. The downside to this plant, and this will sound weird, but it has a ton of roots-- a huge mass of them. Putting it into s/h is difficult because the mass of roots ends up with huge gaps, which I know isn't a terrible thing but I want the hydro to fill in.
Has anyone else tried this sphag on top of hydroton method? I wasn't sure how it would work but so far, this little phal seems to be doing well and may soon be thriving.

But I read on Firstrays, that you water about 1-2 weeks or so. But, I'm confused on this.
I thought you didn't want the reservoir to dry out? Is that true?
As mine dries out FAST, every couple of days or so.
When it is the correct time to water with s/h?
When the reservoir is completely DRY?
Or before it gets dry?
thanks!

http://www.orchidboard.com/community/semi-hydroponic-culture/29637-maintaining-uniform-moisture-s-h.html
Thu, 05 Nov 2009 00:18:32 GMTThis question came to me while reading an interesting thread in the advanced discussion regarding "for those of us who hate watering".
How important is it for the LECA to wick moisture all the way to the top of the pot? My dry climate rarely allows this to happen. I usually have condensation about 3/4 of the way up the pot.
I can't tell if it's having a negative effect or not. Everything seems happy but maybe they would be a lot better if this was wasn't happening.

Usually when I do this I transfer the newly re potted plants into my terrarium so as to keep them nicely moist until the new roots can get a chance to tunnel farther down into the hydroton. This method has worked very well for me over the past couple years and has even saved a couple near death paphs (which are now finally starting to put out new growths).
Of the 6 phals that I recently transplanted, 5 of them are doing great. The sixth however, a small seedling phal violacea var alba, is not doing so well. It has a new leaf starting, which may save it in the end, but the rest of the leaves are quite soft and almost mushy. There is no sign of rot...no yellow or black. Just no roots except for one new nubbin which I am trying to keep pointed down towards the hydroton.
Does anyone have any advice on how I should proceed here? This one I was looking forward to in particular.
Would a seedling heat mat under the terrarium help, or is glass just too much of an insulator for that to help?

About a month and a half ago, I rescued a phalaenopsis from my local orchid seller. The leaves were pretty much burnt off of it, and there were a couple roots that still had some life in them. The plant cost me a grand total of $1.
Well, I basically planted that orchid in a wicker basket full of lava rock. It was watered daily, misted daily and placed on my balcony under shade cloth.
Well, I saw a bit of root growth from the top and decided that it would be time to move it to an ACTUAL S/H set-up, since I didn't have the supplies at the time. In addition to the new leaf growing in now, the roots were completely amazing. The basket (approx. 8" long x 6" wide x 6" deep) was almost completely full of roots! One of them was approaching 2' long! I was totally blown away.
So now, instead of moving my other phals to S/H, I'm trying to find wicker baskets that'll be appropriate. This came about as I'm converting my entire collection to S/H. I figure I'm just going to take the plunge... but wow. I'm still amazed by this phal's AMAZING recovery! I'll get some pictures up soon.
Does anyone have any other semi-S/H stories they've found to work? I know that the wicker basket with extensive drainage doesn't lend itself to the reservoir and isn't exactly S/H... but I seriously can't argue with the results. :)

http://www.orchidboard.com/community/semi-hydroponic-culture/29074-methods-easing-plant-into-s-h.html
Mon, 19 Oct 2009 03:29:54 GMTDoes anyone use a "hybrid" mixture of medium when easing a plant into hydroton?
Here is my idea...
I have a young phal that has several good roots and shows signs of some active root growth. The grower grew it in a heavy medium, close to potting soil. Because of this, it was quite wet and since i had success with another phal in the same kind of mix doing well in s/h (use to a higher water content already?) I figured I'd try it out.
However, this phal isn't one I can easily replace if I mess up. So, instead of keeping it in this heavy soil, I opted for sphag moss. However, because I want the plant in s/h, I decided that I would place the plant with loose, moist moss around its roots on top of the s/h pot and secure it. I have applied bottom heat and am spraying with a water-super thrive mixture that seems to have helped me in the past getting phals to more actively root.
So to clarify, the moss is on top of the hydroton, not mixed in it, and is kept loose and moist so as to prevent suffocation and water logging of the roots.
So what do you think? Is this silly of me? I figure it is providing a good environment for the current roots but makes available the medium for future s/h roots.
What say you?:evil:

Thu, 15 Oct 2009 08:06:25 GMTSo it's been about two weeks since I repotted my phal into S/H, and though it's too early to say if it's thriving... it definitely isn't dying yet. I potted by accident into a pot that was a bit too big, though I'm hoping that when the plant takes off that roots will fill it up. It's just a little awkward though, seeing a fat 6.5 inch pot on my target bookshelf.
Anyway, I just purchased a bottom heater and I can't wait to see the results from it. When I ordered my s/h kit from Ray's, the average temp in town was 90 degrees... the day I recieved my kit the temp dropped into the 70s/60s. This California weather likes to mock me...

Mon, 12 Oct 2009 19:39:55 GMTHave you ever thought 1 or 2 of your chids were just Duds?
I have a Max tenuifolia and a Zns Cynosure 'Blue Birds' in semi-hydro since May this year and they have done nothing, nada, zilch except maybe root growth. :scratchhead:
I have dutifully left the Max alone (hates to be disturbed) and fertilized weakly...every 2 or 3 weeks.
20-10-20 BG Urea free for the Max
20-20-20 BG for the Zns.
We have tested the water and it is perfectly fine. I have them in the right light. I tested the temperature.
Shouldn't I see some type of foliage growth, p-bulb, and not just roots?
I'm wondering if they are duds. They aren't suffering...they just sit there and do nothing. :yawn:
I really want to poke them into doing something by next season. :poke: otherwise....they might have to go.
Any ideas? Maybe my fertilizer is off. :help

Thu, 08 Oct 2009 14:29:44 GMTOkay, so I recently procured a Mtssa. Charles M. Fitch 'Izumi' on eBay. It's blooming size, but the problem is that I got it fairly cheap because it was inappropriately cared for and the roots definitely need some help. When I got it, I placed it in a bark mixture and placed it on the shelf with my cattleyas. It had a few good roots, but it looks like the roots went progressively higher on each new pseudobulb... I'm guessing an attempt to get the roots over the soggy media.
Well, it does seem to be growing roots now. Our Orchid society has a meeting coming up where someone very generously covered the cost for everyone to transplant one plant to S/H culture just to experiment with other culture techniques (nothing wrong with branching out, right? :) ). I was originally going to replant my favorite Dtps., but I'm wondering if perhaps the Miltassia would be better suited. Does anyone have any experience with Mtssa. growth in S/H? Also, any thoughts considering the history of the plant?
(I'll get some pictures up as soon as I can get my camera to stop acting up.)
Thanks!

Fri, 25 Sep 2009 21:09:55 GMTHi
I rescued a Lc Angel Love in water culture. 5 dollars for an orchid that had just rotten roots. now i see green roots' eyes and new growth.
I wonder if water culture is viable or if it is better to switch to SH.
Anyway I wanted to try with lava rock. It was available at the Brooklyn Botanic Garden but now they are out of it.
There is an Hydroponic store way out in Queens. seems that is hard to get this stuff at Lowes or HD.
Also I can use the deli soup containers for the medium sized plants - but for the smaller ones I could use clear plastic cups but they are ugly.
I have nice empty glass jars but I could not poke the 2 holes in it.
is it essential to have the 2 holes on the side?
if I just fill one inch of water with no drainage wouldn't the water evaporate or be wicked upwards anyways?
thanks

Fri, 25 Sep 2009 11:52:50 GMTI've been researching a bit and i have a few questions.
I'd like to use lava rock in S/H as i've done it with LECA before but in my humble opinion it looks hideous as i'd rather pot my plants up in some more natural looking material.
So my question is does anyone have any experience with Lavarock vs LECA in terms of effectiveness and any negative effects of using LR?
Also, is it necessary to use nutrients when doing SH, from reading on the forums its not easy to come by in my country (Netherlands) so maybe Epiweb might be a more viable alternative?
Another thing i was wondering is the performance of Epiweb versus SH, from what i read SH is not possible with Epiweb because it doesn't have any wicking abilities.
However, Epiweb does keep your plants moist by trapping water droplets in the web and it's impossible to over water.
So how is Epiweb opposed to SH and is Epiweb a proper material to use on all orchid species?

Fri, 25 Sep 2009 01:21:54 GMTSo being tired of the, what seems like, high maintenance factor of traditional growing medium... the past year or so has been coconut husk... i'm considering going into S/H. It seems like a very simple, yet effective way to keep your plant in top shape. And I read on Ray's site a complaint about cost... but $19 for a kit seems like an incredible bargain. I think I paid $25 for a bag of husk, and I'm on the constant look out for mold, moistness, air flow, etc.
So after spending the afternoon reading a bit on it, I have a few general questions.
I live in southern California and the weather is almost always dry, and lately has been very hot. If I were to repot into S/H now, would these conditions be okay for my phal? It currently has one (visible) root about to come out, and during the last couple months sprouted a handful of new roots. I'm hoping that if I repotted, these relatively new roots would be okay.
Would it help the roots adjust if I kept the resevoir down to a minimum the first few weeks or so?
And lastly, does algae do no harm?
I'm wanting to do this jump right now, b/c after an inspection this morning, I noticed that an older root had a case of mold and was on it's way out. If this was a b/c the root already old and dying, or just a case of mold, I'm not sure. I've kept this plant right by a window that recieves gentle breezes through the day so I'm puzzled that there's mold at all. I've already repotted this plant a handful of times in the last year or so, not wanting to do this every six months.

Fri, 25 Sep 2009 00:48:04 GMTI have two small phals that have not thrived so I decided to do an experiment after reading a bit about s/h.
I ordered Ray's kit and transplanted one of the small phals into a s/h pot 2 weeks ago and have been watering it regularly with some root grow additive and also have a large plastic bag placed over it for the first 2 weeks to keep it humid.
Provided the plants do well, I will compare the growth of the two plants side by side and see which one does better.
So far the transplanted phal seems to be doing very well. It's leaves have started growing longer, it has what appears to be some new leaf growth and the leaves look very thick and green. I did lose one leaf nearest to the pot in the process.
I took pictures at the beginning and plan on taking photos every week or two to monitor progress.
I will post some follow- up pics to show progress (or lack thereof :lol:)
This board has been very helpful to learn what to do in my first attempt at s/h.
One question I do have is that I also have some Orchid Fertilizer but have not yet started using it yet when I water. I have just been watering with some KLN root stimulator. When would you start doing that instead of the root growth stimulator?
Cheers!

A big dust storm blew through and coated everything in a thin film of red dust
It's supposed to be fine clay particles from the soil and dry lake beds in the Western Plains.
Anyway it looks -exactly- like the dust you get on LECA balls, it's exactly the same colour, consistency and it's just as difficult to wash off.
The thing is, various scientist types have been telling people that it's packed full of nutrients and will actually be good for gardens!
So this is my question.. if this dust is the same as the dust on Clay Aggregate, why do we wash it out and why don't roots (supposedly) like it?

Everything has done well, even the plants I bought bare root in November of 2008 and were struggling to stay alive and are now looking like I might have flowers next year (pictures not included)

My den aggregatum has 2 new pseudobulbs. You can see them as the most lateral leaves on each side, The one closest is what I was able to grow this spring in the medium that it came with
The cattleya has a pseudobulb that I knocked off (far right in black) when I was repotting, and the reward of hydroponics is 2 new bulbs, the two on the left ( was already started) and the nubbin on the right near the base of the dead black bulb!!
I hope this is encouraging to those of you who keep worrying about trying this.

The ends where it was growing still seem firm. What should I do at this point? There are not many healthy areas of the roots left. The tips that are still healthy are far down on roots where the top parts are almost completely rotten...

http://www.orchidboard.com/community/semi-hydroponic-culture/27317-new-problems-after-2-years-semi-hydroponics.html
Tue, 01 Sep 2009 20:28:09 GMTI saw Nanella's post about her success with Oncidiums in SH culture. I too have had success with the same variety planted in SH.
Recently though I've experienced some problems with one of my plants. She's a dancing lady type that has been growing in a 7" pot for 2 years. She's grown well and is almost always in flower. About 4 weeks ago I noticed 5 new spikes emerging and then the leaves from her newest growths began to show signs of dryness (accordion folds). Upon closer examination I could see that the newest pseudobulbs were growing upwards on top of mature growths instead of around the edges. They were stacking on top of one another and I concluded their roots were not being supplied with an adequate amount of moisture. To remedy this I sprinkled some more SH pellets between the growths. I've been misting these surface pellets because they do not come in direct contact with ones in the pot. Therefore they cannot wick. I've been careful to not mist the leaves. During this time the leaves from new growth had begun yellowing from the tips. I've clipped off the yellowed tips to determine if this was a temporary situation due to a former lack of moisture or ongoing due to still existent moisture problems. The yellowing has continued to travel backwards from the cuts.
Today, I removed the plant from the pot and checked out the roots. The roots from prior growth seemed to be happy. The were no fresh green roots (from new growth) penetrating the potted pellets. The stacking growth habit of the newer pseudobulbs seems to be the problem.
It's a challenge to keep moisture at the base of the new growth when they're growing 2 or 3 inches above the pot. I also fear that stacking pellets in the crevices will cause the older deeply seated pseudobulbs to rot. I'm not complaining about SH because the plant has been thriving. This was my first Oncidium purchase. It's gotten large and the growth pattern seems to be evolving with age. The stacked growth habit could be natural for mature plants. I really don't know.
Has anyone else experienced this problem and does anyone have suggestions as to how to resolve it? If I divide the plant it will still have stacked growth so I don't know what to do. Is it normal for mature Oncidiums to begin stacking their pseudobulbs? I just feel the need to put something moist around the base of the newer growths but I don't know what to use. The SH pellets are round so they tend to get displaced when I move the plant. After examining the rootsI cleaned the algae from inside of the pot and planted the Oncidium a little deeper. There wasn't much room to play with. Are SH pots available in sizes larger the 7 or 7.5 inches?

Sun, 30 Aug 2009 14:42:15 GMTI recently transferred two of my orchids into S/H (8/08/09) & based on the way the plants are reacting, it appears I didn’t do this at the proper time. My first problem was massive salt build-ups and root burn. I re-cleaned the Prime Agra and re-potted. Now, it looks like one of the orchids is suffering from some type of bacterial or fungal infection. There are black spots all along the pseudobulbs. I watered it with a Physan 20 solution, but now I’m considering taking a more organic approach.
So, here is my question. Should I continue to use Physan 20 or would an alterative option be just as effective? I’m thinking about using a baking soda-vegetable oil solution or the cinnamon-rubbing alcohol recipe I saw on Ray’s home remedies page. I’m not sure if these options will kill this bacterial/fungal infection, but I’m open to suggestion. My ultimate goal is to provide as “stress free” of an environment as possible to help this orchid recover and become acclimated to its new culture. Thanks!
Oh the orchid’s name is Bc. Maikai (c.bowringina ‘Luster’ x B.nodosa ‘ Weaver’). I purchased it from Phelps Farms Orchids in Tampa. Before I touched it, it was a beautiful healthy plant.

I have just recently joind the orchid board and reading up on s/h and having a 5 gallon bucket of hydrotron from the past I took the plunge and put them all in 4 inch net pots in hydrotron that has been used before and was disenfected before storage.its only been a couple of days but here is hoping they all do well as they all have new primary roots activly growing except for the Mac Holmes 'newberry and it has a new growth that should soon be ready to send out new primary roots also the leafe is now about two inches out of the sheath and just starting to unfold a little.
Can anyone suggest how far from a 250 watt hps they should be placed.My humidity ranges from 30 to 60% the 30 was a night time low while I was gone overnight unexpectedly and did not have the light on the timer yet. But I have added a humidity tray and the temp is max of 80 in the day and 70 at night.I am using just reg mg fert 1/2 half rate and a drop per gal of superthrive

Is humidity equally or more important for the roots than it is for the leaves of a plant?
I'm considering buying an orchid which apparently doesn't do all that well outside of a highly humid environment (phal gigantia), but it's far too large for any humidity case I could set up. Most phals seem to do well in s/h, but this one is known to be somewhat temperamental. I don't want to buy it unless I know it has a good chance at surviving and blooming.

I only have a problem with it in a few of the containers and I can't figure out why? I'm sure I can treat it with Physan 20, but I know it will just kill it and the black stuff will still be visible. I'm sure it will also continue to come back. So I am wondering, should I repot with fresh medium or is it harmless to the roots and I can just leave it as long as I don't mind its ugliness?

I went to the Home site after the posts to the board, and saw that the hydro-orchids site recommends letting all the plants dry out completely for a few weeks after repotting. What does everyone do? I watered my plants and they have water in the reservoir now. I have phals, catts and oncidiums.
Also, how much water should be left in the reservoirs before plants are watered on a regular basis (I am asking this for well established plants in S/H)?

Tue, 28 Jul 2009 01:04:14 GMTHi all,
I'm a new member that has been lurking for a little while, and have some questions about converting a grocery store Phal to s/h.
It's roots look pretty crappy from the top, but are better now than originally. It is showing nice growth with a new root 1 1/2" long and a new leaf coming out, and is just now starting to lose the flowers from the 2nd spike (1st spike's flowers dropped a month ago).
While the surface roots look pretty questionable and there is no doubt rotted material in there, it appears that they are doing something and have healed slightly.
From my readings here and elsewhere it is showing positive signs for a conversion, but given the root situation I guess I'm not totally sure.
Secondly, how should I handle the roots if I do convert now? Should I remove anything showing rot, only the really bad stuff, or what exactly?
I've included some pics of the growth and top of medium. Also, I've been using hydroculture (2-stage pot with LECA) for all my houseplants so I have some familiarity in the area.
thanks,
Sean

A few weeks ago I noticed some of her leaves pleating. She still has some space for side growth but has begun stacking her pseudobulbs in an upward growth pattern. It's the stacked pseudobulbs who's leaves are pleating due to lack of moisture. The base of these pseudos cannot touch the potted HP pellets and this has resulted in more of a mounted growth habit. I've sprinkled and tucked additional HP pellets around the base of the uppermost growth (taking care to avoid areas where a spike might emerge), and plan to regulary mist the targeted areas. The additional pellets should dry out after a brief period of time. Hopefully this will resolve the issue by encouraging moisture and root growth without causing bulb rot.

It was pretty clear that regardless of how I ended up potting it the old medium had to go. I soaked the plant and did my best with a pair of tweezers to remove the compacted sphagnum from between the roots.
The problem....the roots are/were quite fine, and four hours later when I had gotten most of the moss out I also figured that I had removed about 1/3 of the roots. Quite a hack job considering how long it took, and there are still bits of moss that I just can't get to.
If I'd put this thing right into S/h the remaining roots (there's still quite a large root ball) and the sphag attached to them would just rot creating quite a nasty mess in the pot, so instead I've just kept it bare root. I pasted on some rooting hormone and have been giving it a daily soak.
The rooting hormone has really done its job and there was an explosion of root growth from the base of most of the canes, the largest of which are about 1cm long now. They're much thicker and more white than the old roots and have bright green tips (also unlike the old roots).
It would seem to be a great time to transfer it into S/h but the question remains as to what I should do with the old roots. If they're going to rot away anyway it would seem logical to remove them before hand and not introduce that kind of contamination to the pot.
Does anyone have any thoughts/advice?
Thanks,
Tyler

I really want to switch over my phal's when the last blooms falls off. I'm concerned a little about the media they are in now, but they seem to be doing ok for now. I've read here several times to wait until you see new root growth before repotting in S/H.
My question is, what is the best way to find out if there is new root growth without unpotting the plant. It's in a clear container, but the media is dark, and aside from the green roots, that's all I can see? Should I look for new aerial growth, or is there a good quick way. Also, how long should the new roots be? I figure the shorter the better. Just can't wait to get them in new, and better, homes, but dont want to kill them. Thanks all!

Tue, 14 Jul 2009 02:37:40 GMTI'm sure this topic has come up and I tried to do a search, but decided I might as well ask again rather than sift through 335 posts
I've had limited success with S/H but I have one catt that seems to enjoy itself. Unfortunately, it's decided to climb it's way out over the edge of the pot. I repotted into a larger container a months ago and it hasn't skipped a beat, but I really had a lot of trouble getting the new growth closer to the middle of the pot. Since I don't relish the idea of repotting every year and ending up with a huge gallon tub of hydroton, I thought - hmm maybe I should remove some of the back bulbs so I can get the plant nice and centered...and then I realized: Wait...how do you do that!?!
Below you can see the new growth and roots...you can see where I tried to pull some of the hydroton off on the other side to try and create some space, but despite my efforts, the new growth is basically right up against the edge of the pot and I will likely have to repot again next year.
Ideas?

Tue, 07 Jul 2009 16:18:04 GMTI'm hoping over the next year or two to move most of my collection over to semi-hydro based on the success I've had so far with some larger Phals and Angs. One problem has come up though...
How do you handle extremely tiny orchids in semi-hydro culture?
I have an Aerangis pumilio that I'm thinking of potting up in a large stemless wine glass. If it works I think it would look great, but I'm unsure how to proceed. With the tiny size of the plant and the very fine roots, I'm not sure how well it would work with the standard sized LECA pellets. Could I mabe crush some of them and mix in the larger chunks with some uncrushed LECA?
All of my phals are in S/H and as such, their pots are pretty full of algae-- vibrant green, but something I don't much care for because I can't see the roots in action.
So I bought Physan 20. I followed the directions but it didn't do anything right off. Is it safe to assume the algae has been "hit" and will die off in the coming days?
Also, because Physan is a chemical designed to kill off things, I thoroughly drenched the pots with clean fresh water, followed by my weak fert.
After applying physan, should one flush the pot or let the physan remain? I know some of the physan will be left behind simply because the hydroton likely kept some behind but I don't want to hurt my orchids and am a bit unnerved with this stuff.
Any advice on what you do would be great-- thanks.

I've recently switched a phal over to s/h. It had good strong roots and a new spike starting and new leaf growth. I thought this would be a good time to switch, but I probably should have checked new root growth which it didnt have...but it was actively growing so i thought it was ok? Or maybe I'm mixing things up...
Anyway...its been in for about 2 weeks and the leaves are seriously drooping and turning yellow. I can see the roots through the clear container (and I also checked the top ones I could see) and they all look healthy and strong...so...whats up with it? Should I pull it out to check the other roots? or just put it back in sphagnum and hope for the best??
Thanks in advance :)

http://www.orchidboard.com/community/semi-hydroponic-culture/25070-s-h-locking-roots.html
Thu, 18 Jun 2009 17:33:05 GMTHello, everyone. I am wondering... Do the plants need to be "locked" into the S/H medium - the way they would in other mediums? I saw a video on YouTube where someone was demonstrating repotting a phal and she said that one of the common mistakes people make is not making sure the roots are "locked in". I don't remember if she used that terminology, but she was able to demonstrate that the plant and pot were pretty solidly "locked" together by lifting the underside of the leaves of the plant and both pot and plant came up without detaching. I have been doing this with all of my phals, but one had super long roots and I could not put it in the same size pot. I tried about 4 times to fill in all of the spaces as best as I could with the prime-agra but in the end, when I tried to lift it, the plant came right out of the pot - roots and all. It was taking me so long, that I eventually repotted and didn't test it because I pretty much knew if was going to come right out again. What do any of you do? Do you see if the plant's roots are locked in?
Thanks so much for any advice you can give.

I found some Red Lava Rock at Lowe's intended for landscaping- or thats what it says on the bag! It weighed a ton, could barely lift it haha.
Can I use this type of lava rock for orchids, i might add some of this rock to my orchid mixes and maybe try some in SH-
I'd appreciate any advice,
thanks all :)

I am a new member. I have already received several warm welcomes. Thank you!
I have a small growing collection of miniatures, as well as a second area of interest. I am trying to grow orchids in fishtanks. I have made a little headway in this effort, and mention a few points in a thread that I recently started over in the Terrariums forum.
I am interested in finding out about more species from wet terrestrial habitats for potential use in these systems. I realize that a wide range of varieties/species have proven suitable for semi-hydroponic culture, but the general idea for my aquarium displays is that they roughly approximate wetland/riparian habitats in nature, so epiphytic orchids are not really suitable. Furthermore, the plants in these enclosures have most of their roots fully underwater all of the time.
Can anybody recommend any promising varieties or species? And sources? I am currently growing a Phragmepedium 'St. Ouen', Spiranthes odorata and several different Bletilla. It is rather early to assess the performance of these plants, but they are all growing in the described conditions. However, I have found that this phrag does not tolerate having more than 1/3 of its rootball underwater.
Since these are intended for year-round display. I think that tropical and subtropical species are preferable. I anticipate that I might have some trouble accomodating the dormancy requirements of my temperate plants, and I will have to remove them from their displays.
Any suggestions at all would be greatly appreciated.
Regards,

I want to show you this method I'm testing on a poor rooted mini-phalaenopsis
It was starting to dehydrating tough in my "orchidarium" ther's 80% RO. instead of making roots made 2 buds and started a leaf so I've started this test on her.
Note the root starting
After 1 day of DWC leafs are much more turgid. After 10 days the leaf that was just started has come to this
The root also got much bigger.
i'm having some problem with mold but i'm going fine with oxigen peroxide so far.

Right now it's growing in what I beleive is marble which doesn't hold much water and allows a lot of air flow. The only problem is I have to water it everyday. It just started putting out new roots which is a perfect time to repot. I'm worried since I bought it in this media that maybe this breed will die in excessive moisture. Any and all comments will be greatly appritiated. Thank you!

These systems make good habitats for tropical fish and other aquarium livestock, while also supporting live plants artisically arranged in a miniature garden composition. Ripariums are often compared to a superficially similar kind of planted aquarium, the paludarium, but unlike paludariums, ripariums do not have built-up terrestrial areas: the emergent aquatic plants are supported instead with hanging and floating planting hardware.
I include a picture above of a riparium composition that I recently put together in a 65 gallon aquarium. I actually have a few orchids growing in this setup--varieties selected because they use wet terrestrial habitats in nature--a Phragmepedium and a Spiranthes. I have a couple of different Bletilla going in another tank. I really do hope to source other suitable species and try some more orchids in my ripariums.

In the past few months, it hasn't been able to put out new roots without the tips turning black and shriveling up, which is evident from the visible shiny salt build-up at the surface of the pellets and brown residue at sides of the pot. I read in another thread that the salts were alkaline, so I tried soaking the plant in distilled water mixed with vinegar and lemon juice everyday for a few hours. But that didn't make a significant difference. Is there any way to purge the salt from the pellets and the pot?

Tue, 02 Jun 2009 00:06:17 GMTHello everyone! I'm proud to say I have finally tried out SH. I did it simply because of the "auto-watering" since my new job and my 9 month old son don't give me much time to take care of them during the weekdays.
I took bits of info I got from the forum and firstrays.com. I Googled "hydroponics Miami" and found a store that sold Hydroton close by and bought this huge bag for $25. The hardest part in my opinion was finding a container. I kept reading about people using plastic bottle and so on... I didn't have any! I went everywhere and finally went to The Container Store, they had some nice ones but very expensive... $4 a pot! I went home and looked online and using my trusy friend again I Googled "32oz clear container" and found an online store that sells restaurant supplies. I bought 25 32oz containers for $6.50!
One problem I had is when soaking the medium it says to mix in Epson Salt and calcium nitrate. I couldn't find calcium nitrate, does anyone know where to get this stuff?
Anyways, I repotted three plants:
Phrag. Mount Fallu
Some Cattleya I got from my Mother-in-law
C. Leopoldii var Alba
I couldn't find any one who had tried a Leopoldii in SH so I'll let you all know in a couple months.
Thanks for looking!

Fri, 22 May 2009 14:10:59 GMTHi,
I have an Epidendrum Mabel Kanda 'Miyao' that I had potted in a bark mixture (bark, charcoal, perlite,LECA, etc.). About 2 weeks ago, I saw that it had started new growth so I repotted it in S/H. I noticed last night that there was a whitish tint on part of the top layer of Prime Agra, so I assumed that it was a fertilizer buildup and that I would unpot it and do the "LECA boil method" today to remove the buildup, then repot. After I inspected it closer, I saw that one of the old, very small aerial roots had a whitish tint to it but also had some white fuzziness on it, as well. I unpotted it and soaked the roots 3 or 4 mins. in peroxide. I plan to repot it this morn., but I don't know whether to go back to S/H or pot it in a fir bark mixture again. I have been waiting for this new growth because I really wanted to get get in S/H, but do you think that the S/H environment is too damp for an Epi, or not? I will repot into which of the two mediums you suggest.
I would appreciate your advise,
Vicki

So i got a couple baking trays from a local restaurant, drilled a hole in the back of each one and attached a brass nipple to each tray. Next i attached some clear plastic hose to each tray and the hose now flows into a bucket.
A layer or marble sized gravel keeps the pots up out of excess water and also helps provide humidity as the trays dont fully drain. :) its been working perfectly! best part is i spent less than $20 on the whole thing!
Now when i water i just pour it in and let it flow out, when im done all I have to do is empty the bucket!

If I understand the usual semi-hydro system, you just need to maintain the water at the right level, the rest is done through wicking. In the case of orchids (is it the same with other plants?) you have to empty the outer pot (or the saucer) before watering to maintain a precise composition of the water in the tank.
Ray's system uses holes to flush the "old" water out of the tank and replace it with fresh one, which is imo easier (I love easy). The pots are also transparent
So I plan to drill two holes in the outer pot, 1" above the bottom and use it as a tank, the hydro I bought will contain the medium (and the orchid, of course :biggrin:). Are ther some special types of drills I should use for that? (The outer pot seems to be made of glazed terracotta or something similar). Also should I do that under water (like for glass?)
Is the fact that it is opaque will have an impact on the growth of the orchid?
(sorry for using terms that are not really appropriate but I hope you get the meaning ;) )

But what if I have a plant happy in it current plastic pot (transparent) growing in hydroton but it isn't an s/h pot? Could I potentially set the pot in a tray of water to act as its reservoir (like its humidity tray), make holes higher up so it still gets good air circ and leave the pot in that tray? It seems to me that it is fulfilling the idea of the reservoir but using the entire humidity tray as the reservoir AND for added humidity. your thoughts?

The question concerned the practice of withdrawing water and/or fertilizer to initiate blooming. The response covered nearly the gambit of potential methods. Old practices die hard and in some people,namely me, perhaps hard doesn't really describe it (right Ray). So, I flushed them a couple of times with just water and early October moved them to the back corner of the greenhouse and didn't start watering again until February. Nearly all flowered but a couple of things occurred that I really don't understand. There were some plants that did not lose so much as a single leaf during that time and flowered anyway. I am kind of taken aback that the plants could go that long with no water and still retain their foliage. Then, again, I had a small seedling of Den primulinum that I watered all winter and it lost it's leaves the same time as those who lost their leaves without water. It seems to me that just withholding water/fertilizer may not be the sole factor in determining if the plants lose their leaves or bloom. I am in need of some enlightenment!

I have over 50 orchids in my orchid haus, with just about 20 of them potted in SH. The haus has a pretty comfortable temperature range of high 60s or low 70s at night, mid to high 70s or low 80s day. The humidity is anywhere from 60% to 90% or higher at all times.
I repotted my Neofinetia falcata into SH the first week of January and it was a tremendous success with roots growing everywhere into the SH and into the air, etc. But 2 weeks ago I noticed active root growth had backed off and yesterday I decided to take a look at the roots. All those lovely roots have died and some have begun to rot.
The only unknown factor I can think of is my water. I live in NYC and Ray tells me I have very acidic water that can fluctuate extremely (hopefully I am not misquoting Ray). I tested a water-fertilizer solution using a test strip yesterday and the acidity looked fine, but the water is quite soft. Could this be a soft-water poisoning? If so, I assume my SH plants are more susceptible? Is dolomitic lime the answer? I also have a Zero Water filter system, should I use my filtered water?
Please tell me if you need other information to help diagnose my problem. If it is the water or not, I am really motivated to keep my plants happy and thriving so all input and ideas will be appreciated.
As an aside, my Neofinetia falcata is not dead, but without a root system. I have decided to try placing it in water culture (my first attempt at water culture) to hope to keep it alive.

I just bought the loveliest Psychopsis Mendenhall x Papilio and it has a spike and bud. At the same time, I have switched many of my collection to S/H and the orchids and I are loving it --- my oncidium is particularly happy with the change.
Will the Psychopsis like S/H? I have read that they are prone to root rot so it would seem that S/H would be perfect for it. I have searched the forums but havent seen much except for a vague reference to charcoal in the S/H being helpful or critical. Any tips on keeping my new favorite happy and blooming? Oh, and I also read that Psychopsis hate to be repotted. Assuming it will like S/H, does anyone have tips on a successful transfer to S/H?
thanks!

Sat, 07 Feb 2009 15:55:49 GMTKind of long, questions below in bold-italic, if you don't want or don't have the time to read the entire post :rofl:
Two weeks ago I transferred a not so thriving Phal into S/H. In fact it was only surviving, building no roots for almost a year, the last leaf was way to small and in December it started a spike which I removed. The leaves where a bit limp.
I tried several things but couldn't get this baby growing. Despite it had no root growth I decided to try S/H. It was a desperate attempt to nurse it back to health.
During the 2 weeks in S/H all the leaves firmed up again, I had to remove a bit from roots twice but now it seems stabilizing. It already had some black spots along the roots so the roots where in poor shape once I transferred this Phal to S/H. Keep fingers crossed for this NOID Phal. I considder her as my learning project :_(
I always wanted to try a healthy Phal. in S/H. I decided to use a very healthy Phal. NOID, it might be Phal. Anthura Gold. Healthy leaves with a lot of new root growth. I repotted this Phal 2 months ago and was surprised with the new root mass. New roots where thicker than the old roots and non of the roots showed signs of rot. I didn't have to cut a single piece from this plant. Roots where very long and branched. A good start for transferring to S/H I think?
Carefully I cleaned the roots and stem and removed every piece of bark I could remove... soaked it in Superthrive etc.
I found a pot which can contain 1 liter and had difficulties fitting the roots in the pot. Carefully I manipulated the roots in the pot and worked the LECA around the roots.
On the stem I noticed new growths. Two unidentified ones underneath the old (cut) spikes and one new root that was under a yellowing leaf that I removed last week.
I'll watch this baby daily LOL. Questions::scratchhead:
What do I have to look for now she is recently transferred to S/H?
Is it beneficial to flush the pot in the beginning more often?
Can I use Superthrive in S/H or should I leave that with these healthy and actively growing roots?
Thanks, Nicole

I have quite a few plants in S/H and things had been going well for weeks, but now I see that some of my S/H repotted plants may be starting to fail. The roots that were growing so well have died, blackened, and are starting to slime. A few of my Bulbophyllums look to be the hardest hit (particularly a Bulb ramosii and a Bulb liliacinium). The ramosii still has older roots that are green and viable, but the new roots that were actively growing have been lost.
Could this be from an overdose of fertilizer? superthrive? K-L-N? I feel like I saw this problem after misting on superthrive... Is overdose or burn a common problem in S/H?

Sat, 31 Jan 2009 02:20:51 GMTHi,
I have either a buildup or moss problem on the surface of my PrimeAgra medium. :photo: It's very hard for me to tell which. I know this problem has been addressed in the past because I just read the thread last night, but I have looked for it tonight since I realized I have the same problem and cannot locate it. I do remember that Ray explained what the situation was all about and also gave advice to the member who posted the thread, as did some of you.
Since I started growing orchids less than a yr. ago, I have watered them using our home filtering system. A few months back I noticed the same problem that I have now, but less severe.....only a very light dusting of white "powder" on top of the medium. I thought this may be a fertilizer buildup (I use Dyna-Gro liquid--7-9-5) or else some chemicals may have been getting through our water filtering system. Whatever the case, I switched to distilled water, but continued my weakly-weekly fertilizer regime. The buildup problem didn't lessen but it didn't seem to have gotten noticably worse, either. I was starting to water my Mtssa. tonight and saw that the buildup (or whatever) has gotten worse now, and also a crystalline-looking coating has accumulated on the base of the pseudobulbs. I also saw some yellowish-brown patches along with the white. Some of the leaves are yellowing, too.
I would appreciate help from any of you who know what is going on and what I can do to solve the problem.
Thanks in advance,
Vicki

Wed, 28 Jan 2009 04:20:51 GMTI saw some pictures that Underground posted and didn't want to hijack that thread so I'm asking here. My fan blows directly down onto most of my s/h plants and it's hard to keep moisture in the pot. Does having some spagh on top do a good job of keeping it in? And what are the drawbacks? I lean towards s/h because I have a bad habit of over watering and it solves the problem... Is there anything besides spagh that does well to hold in moisture but keep air moving?

Newest pbulbs look good, but older ones are shriveling and looking like maybe they are rotting. Am I interpreting this right? Do I need to retreat with the fungicide or leave things alone?

This is my Catt in water! I got her this time last year in bud. After about a month she had gorgeous green flowers with purple lips. The flowers only lasted a few days and shortly after the pot started to stink. I went to re-pot and realized all the roots were rotten! As a relatively new orchid grower I thought my plant was doomed. I looked on orchid board and saw a post about water culture and decided to give it a try. When I put my precious in this beer mug it had no roots at all. Now it has plenty and two new growths! I bought some hydroton and I want to transfer her to S/H. She grows fine in the cup but I've been wanting to try s/h forever and I figured with such robust root growth right now she'd be a good candidate. If you have any advice on S/H please let me know. I see most people use containers with holes in it above the water reservoir. Is that necessary? I'd like to just use a pretty glass container and fill it up with water part way. The plant is already used to living in water. Let me know what you think.
Ah just for fun. Here are my other orchids growing in water. These two were rootless once. still Not doing great now but alieve.

http://www.orchidboard.com/community/semi-hydroponic-culture/19846-doritis-water-culture.html
Thu, 22 Jan 2009 00:26:22 GMTI've been reading about water culture and really wanted to try it. I just received a small division of Doritis pulcherrima 'Coerules' (this is what the tag said, but I'm guessing it's actually var. 'Coerulea', because nothing came up in searches under 'Coerules'). I know it's a little risky, but it was a free plant, so I thought it would make a good lab rat. I put another part of it in an old orange bag with some moss around the roots to preserve moisture. I've never heard of Doritis grown either way, so I'm trying it.
Currently, I have it in a small shotglass under a mini "greenhouse" on top of a light fixture so that it receives heat to promote root growth. There is a very dilute fertlizer in the water. I don't have any algae yet, but I have a covered glass of water under the light to attempt to grow a stock algae source. I treated the plant with listerine, because I've read that it can be used to sterilize orchids and I am a poor college student without easy access to other materials.
The clouds have moved in, so for the next week or more, the chid receives less than 1000 fc, perhaps as little as 100. I intend to wait for new root growth before I move it into a brighter location.
I know that Orchidineverwindow has experience with Phals in water culture, so I was specifically wondering if you have problems with water soaking up into the base of the leaves and, if so, how you treat or prevent it. Currently, water seems to soak up to the second leaf but does not make it to the top two leaves. Also, should I maybe try to get my hands on hydrogen peroxide or something better than listerine?
Any other advice anyone can give me will be most welcome! I always forget or don't think of something.

I am thrilled to see so many S/H threads - the forum has kept me busy soaking up S/H knowledge for days. It convinced me to go forward and transition the bulk of my collection to S/H.
I recently completed construction of my gorgeous new orchidarium the "Orchid Haus" which is 48" tall, 48" wide, and 19"deep. Sitting on top is a 6-bulb T5 fixture. I moved all my orchids, nearly 40, into the Haus as well as a bromeliad and two staghorns a month and a half ago and turned on the lights. (I live in Manhattan with a bank of drafty windows facing north - not ideal orchid conditions!)
After a month and a half in the new enclosure (they were horribly overcrowded before and all catching rot, etc.) I am watching tremendous new growth - it is so exciting after all that disease trouble that I started getting addicted to the idea of S/H. I read Ray's site "cover to cover", then the orchid board's incredible depth of information, and realized that the timing was ideal with all these new roots popping out all over.
To date, (one week ago) I have changed over:
2 Cirrhopetalum Buckleberry "Lovely Elizabeth", each with a new growth and flush of roots
3 Bulbophylum cornu-cervi, each with a new growth and flush of roots
1 Bulbophylum ramosii aka flavescens with one new growth and the start of roots
1 Bulb. scaberulum with a new growth (I repotted a little too early here, maybe - no new roots as yet!)
1 Bulb. saurocephalum with a new growth and fantastic roots - the roots here are visibly reaching for the PrimeAgra
1 Bulb. lilacinum which was struggling to put on new roots in the old enclosure and is putting out terrific root growth from both new bulbs in the new Haus and new S/H medium
1 Bulb. falcatum which has put out new roots like crazy from one established growth and has decided to add two new growths as well since moving to the Haus!
and now the interesting stuff:
1 Neofinetia falcata - was DYING in the old enclosure and since the move has started putting out wonderful new, thick, heavy roots. I switched it to S/H and hope to see the new growth continue. After this first week things are looking great with new roots reaching for the medium.
1 Bulb. macrei which was suffering terribly from leaf-rot in the old enclosure. I dowsed it with Physan, cut off leaves, and moved it to S/H. It is down to one bulb and one new, young growth with two delicate, but growing, roots.
1 Brassavola little stars - perhaps the most desperate situation in my entire collection right now. I debated repotting to S/H since I hadnt seen any evidence of new growth since moving to the Haus but the medium it was in (sphag moss) was saturated week after week. When I unpotted - all the roots were rotted away! It is in S/H now, and I have my fingers crossed. I cut off as much of the rot as I could get to and dowsed with Physan.
So, any advice anyone can give will be much appreciated - particularly if you have transferred these beasties to S/H before. A side question - should I treat my rotted root stumps with cinnamon? ALSO, and perhaps most importantly, I want to transfer the following to S/H, but cant find any references:
Thank you everybody and keep up the wonderful growing!!!!!

I used PA in 2 as media and another product that was cheaper and suppose to be Close to P/A
1 I prepared both using Rays web site as a guide ( the other media was not suppose to need prep but I thought it did)
2 I planted the cats in the media's and placed them on a bottom heat mat maintained at 79 degrees. I kept the 02 at 1200 to 1250 ppm during the day. The plants were subjected to daylite T-5 bulbs 14 hours a day. They were Misted automaticlly 2 times a day for 50 seconds the mist contained a 50 % MSU and 50% orchid Pro.
Every 3rd day I would flush with plain water and KLN Root Grow.
PA out wickes the other sightly but the other has a good ph
Below are the results of three week on this experiment.
1 The roots in the PA go down toward the water.
2 The roots in the other come on the surface and seem to take the path of least resistance. ( Pa has more air space the other seems to pack more)
3 I think the 02 and the bottom heat are a substantual help in establishing in S/H . The mats are the heat mats used for starting seeds with thermostats on them. The probes were put in a pot of each media about halfway down and treated as they were plants.
Picture 1 surface roots the other The roots you see at the bottom of this pot are old roots that have so far survived
Picture 2 & 3 Deep roots P/A
Im not naming the other I don't want to get in a contest between both MFG's I just wanted to see if the bottom heat and O2 help development and what the 2 mediums responded to. Would I buy the other again yes I would I see a definately use for it in some other orchid species, would I use P/A again Ive got 2 50lb bags ordered.
Im think I'm going to put circulating hot water system in on the starter benches I think I would have better Temp control and would be cheaper to operate in the long run
I have a friend (believe it or not) that has the system under all his benches and he just gets amazing results and cut down on heating bills in the winter with the closed loop system. I know it will be hard to believe he dosent do orchids which I find hard to believe he does bonzi and other things..
I think a small system like they use under concrete floors using a small 110v hot water heater would do it But I think I'll tweek this for awhile and see what I get. I was tempted to raise the heat to about 82 or 83 but I'll try that next and see if there is a difference. I like to take small steps and see what happens.

the pots are .99 cents ea. and the hanging rods I think were 2.98 ea. I silaconed the holes in the bottom up and drill my holes on the hanger side 1/1/2 up since they hang on a slight angle. The bottom board is to level the pots each application would be different. I staggered the pots so the runoff from the pot above musses the next pot down. This really adds a lot of space in case you might find another homeless Orchid that you just have to adopt.
I also cut the hanger off several pots and now they are 99 cent heavy duty S/H pots.

After about 3 weeks, I noticed one of the bulbs was turning brown and soft (rot) from the base of the pbulb. I decided to repot before it spread, and found that the root system was mostly gone. But, there were some roots that look okay, but not great, so I left those on (which may have been my mistake). I removed the rotting bulb, which ended up dividing the plant (which was fine, it had 10 or 11 pbulbs when I purchased it).
I wanted to try and repot into S/H (although now folks tell me this was a bad move). Following rays advice, I covered the base of the plant in a plastic bag, using clips to secure it to keep the humidity up around the plant about 1.5 weeks ago.
Today I noticed that a couple more pbulbs had started rotting from the base up and that mold had developed on them. I decided to try putting the plant in sphag-n-bag as a last ditch effort to save this plant (now two, due to division)
When I pulled the oncidium out, all the rest of the roots had turned mushy. I removed the rotting bulbs, removed ALL the roots (since there were all completely rotten) and am soaking the plants per sphag-n-bag instructions on ray's page.
Can I use the S/H media this orchid used to be in again? Or will that risk spreading rot to another plant? Is there any way to clean it? I'd just hate to waste all that good S/H media....

I decided to go for it but i just wanna know if anyone has ever tried it with success. The roots looked fantastic when i took her out of the pot. I just want to know what to keep my eye on.

Sat, 06 Dec 2008 14:25:44 GMTI recently repotted a couple Catts into S&H and am trying the Spag-n-Bag approach to help induce them to send out new roots. How long do you normally keep the orchids in the bag? Do you keep the bag completely sealed or leave a small opening for some air to get in? Do the orchids need to be watered at all while they are in the bag? Any other tips on this process would be appreciated. Thank you.

Sat, 29 Nov 2008 15:18:57 GMTI have been growing s/h on & off for 10 years or so with ok results - lots of healthy growth, few fatalities but not much flowering. I'm sure it's mostly my fault due to health problems and neglect.
I have searched and found lots of posts regarding the clear pots with holes. I have lots of those as well as net pots in cut off soda bottles etc. with holes.
My question is regarding the pots with no holes with an inner liner for the expanded clay pellets and a water level indicator. What is the ideal watering/fertilizing regimen for this type of system?
TIA,
Ken

Fri, 28 Nov 2008 14:58:50 GMTHere's my problem, I have several plants transferred into S/H last season and they can't seem to establish themselves. The ones that were already acclimated have done very well for me. Therefore, I'm wondering if there's any vendor out there that sells plants established in semi-hydro... because I'm afraid of the whole proccess of aclimating the plants again, and risk putting the plants to stress and possible death. I know that First Rays Orchids has them occasionally.
I also want to know which one would be an easier orchid to acclimate into S/H, I killed 2 Phalaenopsis while putting them into S/H, so maybe another genus.

After 30 odd years of struggling keeping my Orchids healthy in some of the most nightmareish places I finally built my dream greenhouse. I constructed it ot of western red cedar, totally from rough timber, plainning.routing and driving screws there are no nails took me 7 months of evening and weekends.
Totally automatic and runs off of solar panels and 12 volt dc systems as storm backup
My new challenge shifting 145 Orchidc plants to S/H I tried it I like it. Yu ca see more at bobweis,com in the Orchid section and believe me get ready for questions at 65 I don't change easily

I had two Phals and had grown them with no problems...What first brought me to this board was my first non Phal orchid plant, which I adored. I had two Phals and had grown them with no problems (honestly, they pretty much grew themselves) so I figured I'd try a different one.
My first orchid was from Smith and Hawkins (got it on clearance for $15). After less than 2 days one of the psuedobulbs started rotting.
I was worried maybe I had caused it to rot when I watered it (by not being careful and making sure no water drops got on the plant pbulbs because I didn't know that water on pbulb could cause it to rot) but many people told me that it was unlikely that I killed it in two days, less than 24 hours after I watered for the first time. (Plus, when I went to the store to about it's bad condition, they told me they only put plants in "distress" or ones "not doing well" on sale).
A week after doing everything everyone suggested (and too early to tell if my orchid was going to make it), I realized that the orchid was under warranty, so I exchanged it for a maxillaria tenuifolia. (note that Smith and Hawkins failed to tell me about this warranty when I went in).
My new orchid looked to be in good shape when I purchased it. I watered it very carefully with a special water can (making so NO water got on ANY of the leaves of pbulbs) and I waited for it to show new root growth before replanting it to S/H
Then I noticed two of the pseudo bulbs in the middle of the plant were rotting (what the heck??!!! I had not been over watering or letting it sit in water or anything)
Then I read that this can happen if the roots under it are rotten. So I repotted and found that while the top of the soil looked really good, the bottom pretty much mud and decayed wood. (I hate Smith an Hawkins and won't buy another orchid from them EVER, they're 0/2 currently)
I think I'm now with the camp that repots as soon as they get the plant....if I had, maybe I could have prevented losing 1/3 of my plant.
Anyways, when repotted today, I divided the plant into two plants with good bulbs (each with 4+ pbulbs, following the natural division of the plant like I read up online from a link someone posted to my Phal thread...I feel brave!), I threw away the rotting pbulbs, and then trimmed all the rotten root on the two divided plants, moved both plants to S/H (because I've read many threads that the pbulbs plants love S/H and because I don't care for traditional potting soil--too many variables)
Since the plant was poorly timed for the S/H, I soaked my media for several days with espisom salt and the calcium salt (from ray's orchids). then I rinsed with clear water several times, and did an overnight soak in KLN root grow
I read on the board that I should put the plants in low light to help encourage root grow. How long should I do this for and by low light, does this mean in a room with the shades closed that gets a little light? Or should I be shooting for near darkness (almost no windows)?
Also, should I water with just KLN root grow at first (if so, for how long) or should I water with both the MSU fert and a couple drops of root grow, like I do for my Phals in good shape?
Any other tips would be appreciated. I can't justify buying another of the oncidium hybrid I lost (Tiger Crow, which I ADORED) until I figure out how to grow my free replacement pbulb orchid. (especially since I'll be buying the Tiger Crow from a reputable orchid grower, and that won't be cheap!)
Thanks!
Niki
P.S. I really don't care for traditional media. I don't like not being able to see the roots. I also don't like dealing with decomposing media. And I really don't like worrying about overwatering them. I hope all the orchids I end up with like the S/H...Just my :twocents:
