Granted, the "ice" part is bothersome, and if folks could learn to barely trickle lukewarm water on their plants in sphagnum, it would be a lot better, but most of those plants are purchased to enjoy and toss, so...
I am a newbie to the group. Just joined today!
Would like to convert to full water culture asap (before this 2016 Fall)!
Saw pictures you have posted, seemed you cover the crown and all?
I saw on Facebook, most mentioned that only 1/3 of the root should be in water?
Yours looked very healthy indeed.
Also when winter arroved, did it have any impact on the growth?
What I meant is, the water temperature would be quite cold?
So water and light can produce the blooms with no problem right?
Thank you very much.
Really like the water culture idea.
been a while since i was on here last asking about water culture as i had a phal with virtually no roots or leaves. put it in a little pot with water and its never looked back. i used to change the water to start with but now i dont. just top it up. bless it, its throwing up a spike. about 4ins long at the moment. was very surprised as, although it now has roots, not a lot but good strong ones, it only has 2-3 new little leaves. wish i could upload a photo, but never been successful getting it small enough.
I spent the last few weeks converting all of my orchids except the paphs into full or semi water culture. I've been watching all the utube videos and decided it made sense for my conditions. I have even seen new root growth in just a short time. The only reason I didn't convert the paphs is because they are doing extremely well in a semi terrestrial mix I made up. I even purchased new orchids for the first time in months. I will keep you updated on how it goes.

Whenever a plant takes up a nutrient ion, it dumps a compensatory one, and that is going into the medium - in this case, the water. Add to that the various metabolic wastes the plant produces, and you've basically got the plant sitting in its own ****! Eventually, it will poison itself.
If a root picks up a cation (mag, calcium for example) then it will release a hydrogen ion. Too much hydrogen in the water will make it acidic.
The people successfully growing in water culture are using distilled water so there isn't going to be much ion exchange. I am using rain water since I can collect it easily. The water needs to be clear all the time. About 1/4 to 1/3 of the roots are in water for full water culture. Once a week I cover all the roots with water for about 15 minutes then dump it and add fresh water to the 1/3 to 1/4 level. I check daily and if the water becomes cloudy I check the roots for any that are rotting, cut them off, treat with 3% hydrogen peroxide, let them dry then place them back in clean water. This happens for a while when starting them in water culture. For those orchids that like their roots to dry out such as the catt types, get a day of soaking, then two or three days dry.
