That's the reason I don't carry "cool" orchids, Lore. They would do fine for six months and probably struggle the other six months. I don't have any AC out in the greenhouses and besides, all my orchids go outside in April and remain outside until October/November. Our average high during those months would probably be 85 F+ and it isn't a bit unusual to have many days in the mid to upper 90's. Some years (three years ago) we have days 100-110.
