YetAnotherOrchidNut, I’m partially with you on this. I’ve been growing my orchids in s/h for 11 years now and some of them have declined. So I had to move to the bark all of my mini Angraecums, P. celebensis, Epidendrum stamfordianum to name a few. The others are thriving in s/h (cattleyas, dendrobiums, chysis). So I don’t know what’s a culprit in my case-the temperature or something else.
