from a neighbor here in Broward County!!
I'm keeping most of my orchids out in the Florida room. So far, I haven't turned on the a/c out there, but I do have the windows open. I have kept a few in the bedroom/den though, and that room is air conditioned, and I keep a fan going (doesn't get really cool in here, even though the thermostat is anywhere between 70 and 75). The bedroom orchids are on a table in front of an east facing window, with sheers between the window and the plants. So far, they haven't complained, and seem quite happy and healthy.
I'm using bark right now, although my Vandas are bare root and just hanging. I did have an incident with mealy bugs on my Phal, so that too is bare rooted now, until I get a chance to repot her.
Don't know that any of this is going to be helpful to you, but I did want to welcome a neighbor!!
