Results after 6 weeks
I thought I would post a few pictures of some of my results in 4-6 weeks. I put all my plants (20 or so phals, catts, oncidiums and 1 miltoniopsis) in semi hydroponics over the first 2 weeks of August. 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)
This oncidium had a dead pseudobulb in July. In August I transplanted it. Now you can see the new roots
Most of my phals lost 2 to 4 lower leaves, at the same time growing new leaves briskly
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.

I am sorry to report that I lost my first orchid in s/h this week. It is not one that is pictured. It never did well. I am not sure what it was, but I think oncidium type.
On the brighter side, the rest of my plants look great !!! (Read that - S/H saved the rest of my orchids from their previous near death encounters while under my care)

Jerry, if you lost a plant after only 6 weeks or so, I would speculate that it wasn't in the right part of its growth cycle when you transplanted it, and/or it was too cool to kick it into a growth spurt.

This was after 4 1/2 months. I transplanted it at the beginning of August. It never did much growth after that, unlike the rest of the plants. As I say, it may have been the prior care that put it in critical condition, the resuscitation efforts just postponed the death

I grow practically everything in s/h culture - excluding vandaceous plants and tolumnias
I have some roth hybrids in s/h, and they are doing great.

I put a small phal in S/H 5 months ago. It kept starting new roots and they would turn brown and wrinkly as soon as they hit the stones. Kept putting out new leaves, tho. Well, yesterday when doing my watering/fertilizing I realized that those "shriveled" roots are growing nicely down in the stones!! Yeah!
Message: have faith, and patience (a trait I am sorely lacking in)
And happy holidays everyone

Why not tolumnias, Ray?
