temperature ranges for my orchids in GH

[nutgirl]

First of all, thank you to everyone on this site!!!! I have learned so much.

I have a small collection that I've been growing as houseplants for several years. Phals, dends, a cambria, and a bollopetalum.

This spring I set up a small GH and the change has been remarkable. New growth and roots galore. Everyone is responding. Because of the size of the GH and my climate (dry and hot) keeping the GH cool and humidified has been a challenge. I use a rinkydink set up of fans, misters and cooler pads. I try to keep the max around 85-90 but sometime the temp goes has high as 95+ and can get into the 50's at night. (Usually around 60) I try to keep the humidity above 50. My frogs seem to like it.

Are these conditions too hot for my plants? How will I know if it's a problem for them? I recently got an ascoscenda, would it like these conditions? I'm using the glass vase method.
