Anyone using full water culture?

I am now growning 3 orchids in full water culture.
Which means growing the plant bare rooted and putting the roots in a glass vase or watertight container and keeping about an inch or two of water in the bottom.
I first tried it on a mini phal that was bought growing in spagh moss, but it's flowers were not opening and the buds started to drop. I took the moss off and tried this method. Within days the buds started to swell then open and stopped dropping off. The old roots started to sprout fresh, thick green roots.

Yes, ive grown Phaelenopsis pulcherrhinma for a few years like this. This is how they grow in nature so it wasnt much of a stretch for this species. I think most orchids will tolerate their roots in water, as long as the water is well oxygenated.

Interesting, I have never tried this or heard of it. But it must be working.

A lot of names are given to whats essentially the same thing, e.g. Semi-hydro, water culture, etc etc. They all seem to work by keeping the roots moist or wet but well oxygenated.

Recently i started using clay hydroponic pebbles for many orchids either with or without the semi hydro aspect, i find the clay holds enough moisture for the roots but allows plenty of oxygen in, it can also be allowed to dry out fairly quickly for those plants that require it. And the main attraction is it wont rot and become anaerobic like even coarse bark can.

Edit: same photo i allways dig out on these occasions but i allways get a kick out of looking at them again,
Nature allways gets there first, natural semi-hydro/water culture,

just type in google images, "orchid full water culture"
or do the same search in youtube and you will see videos on folks doing this. I prefer it over growing in clay balls , hydroponically as I can always easily see the roots and how healthy they are.
here's a blog post on it
