At 80-90 I would be dead forget happy plants. I have steam heat and there are times I turn that to 62. Steam heat is constant and it was too hot even for my mom when I turned it to 68 and she liked 80s.
I cannot take that much heat indoors. If it is dry heat like Arizona I was comfortable when their temps were running in the hundreds. As long as I can dress according, aka nude enough not to be arrested, I am fine with dry heat. Inside forget about it I have to be cool.
