    I have been experimenting with S/H and have Phrags, Catts, Brassias and some Dendrobiums in S/H. The experiment has been ongoing for years and I have had very few problems. Every year I add more plants to S/h culture. I know a person that has all of his Paphs in it. There are others that grow in it exclusively.

    So far on the positive experience list:
    Phalaenopsis
    Paphiopedilum
    Phragmipedium
    Cattleya
    Brassia
    Dendrobium


    Possibly on the NOT list:
    Miltonia?
    Cymbidium?
    Any thoughts?


    No far no mention of Cypripedium - also on the yes list with the other slippers? And no mention of Oncidium, which I would personally guess to be ok with s/h?

    (I don't even have some of these personally, but I thought it might be nice to get people thoughts in general on various genera in s/h)

    Oncidium has been reported to be VERY adaptable to S/H.

    Of phrags, Besseae is NOT suggested for s/h. I do not think that cypripedium would do well based on my limited knowledge of what their requirements are.

    I have had great sucess with Miltonia's see thread Pics of Semi hydro success with 3 of my Milts in bloom.

    Oncidium alliance orchids, such as intergenerics and hybrids are a natural for s/h. I also have great results with Cattleya's, Paphs and Phrags. I have had mixed results with Phals, and tend to grow most of them under traditional culture, but do have a few in s/h and they seem to be doing fine. The key is to convert to s/h when new growth occurs, as assimilation to new culture is much smoother. Otherwise, you have to nurse them along.

    I killed 20st bellina seedlings when I switched to s/h. Note to self: repot into s/h when the plants are strong.

    tolumnias are said to rot in it.

    vandas are believed not to be ideal candidates in the long term due to their long root systems.

    Yeah, I was wondering. Has anyone had success with Cymbidiums in S/H? I have one test candidate now because it didn't seem to like anything I did for it, so I figured it would either thrive or die in S/H. Sink or swim time!

    But I'm curious, any takers on cymbidiums in s/h??
