Excessive heat ????

OK, sitting here thinking too myself on how to keep these temps down in new room and daydreaming looking outside. Its friggin hot out there(87) and it isnt even summer yet. So after thinking about the crops we grew in Carolinas and in Fla here in the past, I was wondering how it can be like 96-98 or hotter almost every day in the summer and my outdoor crops did nothing but flourish. Two years ago we had like 20 some days straight in excess of 100, Shouldnt the heat kill them?

Due to higher CO2 levels outdoors, plants can tolerate higher levels of heat. Also the high humidity levels tend to help the plants out a bit.

There's def. some give on the temp. 25c might be ideal but I had an extremely potent crop when the temps were a constant 30c lights on

24c when on 22c when off does me fine
