A couple years ago I killed a few fawcettii seedlings. My guess is that they aren't as tolerant as funalis.
You have a greenhouse?! Heh. Do you attach any orchids to trees?
I have lots of orchids attached to my trees. Problem is, since most of my trees are in the backyard, there aren't many people who can enjoy the orchids, unless of course I take pictures of them, which really doesn't do them justice.
Lately I've started attaching orchids to the trees where my friend lives. It is a condo type community so the trees are semi-public.
Just now I wondered if I should attach my funalis to one of the trees there. In theory this would mean that if you were ever in the LA area, you could see the orchid growing on a tree whenever you wanted.
Several years ago there was a project to attach orchids to trees at a Miami dog park...
Community Orchid Project - Dog Park Miami
More recently there was a project to attach orchids to some street trees in Brazil...

Oh yeah, in Florida there is also the million orchid project...

Unlike Florida and Brazil, here in California it rarely rains during the summer, so the orchids on trees need to be watered, which is why I try and focus on the driest growing varieties.
It's hard for me to imagine how awesome it would be to live someplace where orchids on trees wouldn't need to be watered!
