I have about a dozen mounted orchids hanging from the mesh shelving that came with a small,portable G/H. We hung that from hooks that were already on the underside of the mantel of our fireplace (which we never used, of course
). This weekend I moved two of the mounts--Brassavola nodosa and Bl. Yellow Bird--back to pots. I did have to hack away at the cork on the Yellow Bird, but luckily she fit just fine in a six-inch orchid pot. The roots had too much of a hold on the substrate to even think of trying to remove them--Anyway, I plan on moving the other mounts to pots, also.
I didn't realize they needed to be sprayed every day and I am much more of the water-once-a-week kind. Live and learn, I guess
A friend has a few large mounted phals, but she says they are not doing too well. She can't give them enough moisture...Maybe it's where we live--not great humidity here. Best of luck with your den...
