I also have ghost orchid babies but I don't have such a fancy setup for them. They hang out on a piece of onion bag mesh in my shower and I just take a shower to water them. Yes, I water my plants with tap water(course, Seattle's tap water has a reading of around 30 ppm. Yes, I know someone with a ppm measuring tool.). They've had this setup since I got them over a year ago and they're still alive and growing(I don't even use fertilizer at all.).

That's awesome. What kind of light do they get?

1 week check in point

The collection got their first feeding. A diluted solution of MSU that clocked in somewhere around 100ppm. If you read existing guides, the recommendation is for around 75ppm and at that level you can load them in a mister and feed them all the time if you want.

I had to pull 3 of the clusters out including one that had about 3 inch roots as they were rotting from the protocorm. I had spotted these inside the flask and they were already on their way out, so the deflasking event just sped up the culling process.

Quite a few of the albino clusters seem to be settling in, neither withdrawing nor showing signs of active growth, but across the board, clusters that had what I would consider borderline viability are starting to show signs of decline. The clusters that had yellowing or blackened protocorms are moving on. The roots still seem to be intact so I'm going to hold on to them until the roots show signs of decay.

The good news is the robust clusters are still robust and the roots are continuing to show signs of growth so that's a good thing. You get so many seedlings out of the flask that you can afford to lose a few (though I hate the idea of losing any of them no matter how small they are).

By my last count I'm down to about 17 or 18 viable seedlings, which all things considered is astonishing. One thing I've had to do is to back off on the watering a bit and allow for more drying time. Apart from that - everything else seems to be proceeding along as I would have hoped.

I'm going to keep them in these conditions for another 30-40 days, at which point I believe they will have properly acclimatized. At that point I'll moving them into their permanent enclosure. I think for that next stage, I'll be increasing the light levels from 500FC to 4,000 FC over the span of a month, increasing by about 1k FC every week. I'll also be experimenting with different mounting options.

I have on deck...
* mockernut hickory bark
* driftwood (boiled to leech out the salts)
* burlap
* terracotta pots
* some DIY bark things I'm working on (orchiata siliconed to some surface to simulate a bark slab)

I will also at that point, attempt injecting CO2 into the chamber. I'll start at 1,500PPM and slowly increase up to 3,000 to match the attempts that have been made in the past with this very same injection technique.

So yeah...still going on strong and thinking about picking another flask so I have more different things I can experiment with

Umm, a south facing frosted glass bathroom window. As do all of my other orchids since they all live together. Apparently lepanthes love that spot and bloom. A lot.

You might want to try an onion bag, they seem to like it a lot. It lets them get a bit of air movement and traps water droplets for them. I don't have any tools for my plants 'cause I have no money(and I would forget to use them as well.). I've had these guys since November 5, 2017.

That's awesome and a great data point - I'll be sure to include those growing area details in the wrap up video.

Apparently the team at UofF managed to grow them directly off burlap cloth, so growing them on an onion bag wouldn't be that far off and yours are still alive so you're doing something right!

Any chance you can post photos of your ghost orchids?

AAAAAnnnnnd....here's a research paper

I updated the first post with a link to that research paper for anyone else daring enough to try this.

Mini update - I had some concerns on the moisture of the sphagnum bed of moss. I had trouble drying it out in a timely fashion and I believe that accelerated the rotting process of some of weaker clusters.

I've moved everything over to a scrap of burlap now and will see if that improves the wet/dry cycle.

After reading the research paper, I'm switching up my strategies a bit and changing the lighting setup yet a third time. I'm now using a VIPARSpectra 450W to light the tank. This grow light is special as you can control the exact ratio AND intensity across the PAR spectrum, of light being delivered to the plants, which is handy for taking photos as I can shut the red and blue off and just have the white light

You can see the light settings that I settled on in the descriptions. For the next week or two, I'm raising the FC levels from 250 FC to 1kFC which clocks in about 225 PPFD on the PAR Meter.

The goal will be to see how far I can push the light levels beyond the 358 PPFD recorded in the UoF Research Paper. Above a certain level, you have to introduce elevated levels of CO2, so that should be a fun experiment.

For now, I'm happy enough that they look alive and are happy

Fun facts learned from the research paper:
* stagnant air - myth
* symbiotic fungus - apart from germination, no benefit
* Burlap's a decent medium to grow them on!
* they spritzed every 2 hours for 30 seconds during the day - I'm spritzing like once or twice and so far so good.
