Hello again all and thanks for the input! I seem to be constantly struggling with some kind of mold or fungus so I am not sure this method will end up working for me. I have the little plant just sitting aside right now after it lost 2 more leaves. Just going to let it dry and see what it does. Not sure it will make it, but I knew that going into the experiment!

On to the next experiment I guess!

If you want to stick it out, then I'd invest in a fan, and keep going with your expiriment. Not sure where you are located, but I am guessing you have high temps / stagnant air - mold factory.

A fan will keep the mold spores from landing as often, help move the humidity around a bit.

Crown rot had set in it seems. So not exactly a successful experiment. And actually, I live in southern CA (Los Angeles area). Not humid at all really. Typically dry and a tad breezy.

My 1st fwc (full water culture) orchid was a rescue phal, zero "traditional" roots, only about 5 air roots. I stuffed them into a Mason jar, and filled the water to consume the bottom 10%ish of the roots, it converted easily. I now have all 4 of my pals, and all of my oncidium "types" (multiple oncidiums, 2 brassias, 2 brassidiums), and my lone vanda in full water culture. The phals varied in there conversions, only 1 had the original roots completely die off, the other 3 just made the change. The oncidiums and vanda took to it immediately, though I will say it was maybe less than 10% of the roots were in the water full time at the beginning. What works for me may not for everyone, but FWIW, here is my schedule for every single one of my orchids in FWC:

All except the vanda and 2 brassias (has been outside since spring, will come in before temps get to low), are grown indoors all year round. Bottom 10% of the roots are in water full time. Every sunday, the jars are filled right up to, but not including the crown, completely submerging the roots for about 1 hour, with k-lite fertilizer at about 25ppm N. Once a month, a long with the k-lite is a tablespoon each per gallon of Kelpmax and Inocucor. After the fertilizer soak, the water is changed out for fresh new water (this is very important as I have just found out recently). This has worked for me for around 2 years of FWC.

Just to see what would happen, I stuck to the regimen for 2 of my phals, the other 2 I treated slightly different, I did not change out for fresh water. You will clearly see the roots starting to rot on the 2 that didn't get the fresh water every week. All 4 have spent just as much time, at the same depth in water, but clearly changing it out is key. Btw, the flowers on the left, be long to the plant all the way to the right

My vanda just after the full root soak. Some of the roots are very dark, but they are just as firm and plump as the greenies.

Edit, I lied, my 2 brassias are in red lava, oops.

Cheddarbob14 -
I suspect that the reason that you got away with full water when you kept the water fresh was that the fresh water had another secret ingredient - air. When you poured off the old water and added the new, the roots were exposed to air, and also the water had some dissolved in it. The ones that didn't get fresh water didn't get that regular infusion of air. S/H, or traditional media, have a much higher air-to-water ratio, which more closely mimics nature.

all interesting information! Thanks guys

I have a couple more experiments at the moment. One free from a grocery store (the head cashier just gave it to me since all the flowers were dead and I helped her realize why she killed all her houseplants - spoiler - she was drowning them) and the other one a lowes $2 buy marked down for me. (I may have also made friends with the front end manager there, haha) Actually with a chunk of decent roots still. No crown rot. The free one has some crown rot but I seem to have halted it.

what I have been doing is soaking the roots every 1-2 days (depending on how long I can soak them) and then leaving the plants out to dry completely. when I unpotted them I took off all the rotten roots, and left them out to dry and callous off for a full week. While this seems to be doing well, it's way to much work for a long term solution. But so far it does seem a viable way to rescue a sick plant (for rot at least).

I bought some black lava rock to experiment with, but a single chunk doesn't seem to wick water up as well as I was hoping, it's only damp maybe 2 inches above the water line. (I was hoping to try kind of a self watering mount).

But bonus! there is a hydroponic store in my town! and they carry leca and growstone and lighting and ALLLLL kinds of useful things
