I've been growing orchids for years but only recently stumbled upon s/h myself. I've been having great success with Vandaceous varieties that are normally tough for me to grow in potting media. Here's a short list of my s/h successes so far:

Ascofinetia 'Peachy'
Amesiella monticola
Oeniella polystachya

Ludisia discolor

Howeara lava burst
Dendrobium kingianum
Neofinetia falcata
Maxillaria tenuifolia
Pleurothallis restrepioides
Masdevallia Dean Haas
Coelogyne cristata

Has anyone tried C. Leopoldii or Guttata?

Don't mean to reverse the S/H list here, but from the looks of it, maybe we should list those plants that did poorly, or didn't spike in S/H. Anyone have any specifics on Orchids that hated S/H?

Not for S-H
 

2 plants that did not do well for me in S-H are C. walkeriana ( I mounted it and it is doing just fine) and L. sincorana (2 plants have gone to Orchd heaven). Other rupiculous Laelias seem to thrive if you use small clay that dries out rapidly.

I just bought my very first Catts
blc Goldenzell 'lemon chiffon'
blc Mac holmes 'newberry'
lc Mary Ellen Carter ' dixie hummingbird'
Purchased on the 3rd of this month repotted into bark in wooden slat baskets one week later when they started popping out new roots and made a 650 mile trip home with them with no problems.After getting home last week end noticed that the bark I had purchased was getting soggy and slimy at the bottom of the baskets .....yeah Im sure Im heavy handed when watering but they are very small and Im obsessing probably lol.So anyways they are now in s/h with hydrotron to see if if is the cure for my orchid ocd.

I've got a big list in S/H too, however, how do you define "successful"? Adapted? Thriving? Blooming? Because a lot of my plants are still seedlings so I'm not sure if I can say it's successful or not, although they defintely grow like crazy:)

I am going to try a Dendrobium formosum. is it ok? will it bloom? what about the slight winter rest? withold water or just fertilizer?

Good Luck!
