Ms. Angela, My deepest condolences about your husband…So sorry. This is my first summer with a GH, and I might say a trying one. I have tried a Portacool evaporative cooler 3300cfm and it wasn’t big enough. I have 60% shadecloth with 70% aluminet over the top of it. Yesterday’s temps in the GH were 101, but outside temps were about 99. Today’s GH temps peaked at about 93 with outside temps close to that. I have a 42” fan pulling a lot of air through the house and I have been keeping the temps close to outside temps. I’m in Western Kentucky, you and I are experiencing the same hot temps and summer has just started. With that said, I have seen very little visible heat stress on all the orchids. Cattleya’s, Phrags and paphs all seem to be doing ok. Perhaps I will see some effects any day but, not yet. I have been watering about every other day…sometimes more often. Caudatum’s as of yet are showing no I’ll effects. Cattleya warscewiczii are putting on new growths. I have some that are old enough to bloom this year, but no sign of buds yet.
