Little cooler than that. I keep my temps under 72 with lights on and a little cooler in dark. I shoot for 68-69.

I always have problems above 72. good luck

You can grow in temps of 93 degrees. You need to start with little to no nutes becuase of nute burn. You will get a lot of heat stress and could cause your plants to be male or hermied. Can't you make it cooler in there?

the higher the volume of airflow, the higher the temp your plant can tolerate
guessing that your plant looks a bit stressed?
but 90+ is pushing the envelope

hmm i would assume that a cfl gets hotter than 93 and people put those no farther away than 2 inches.. how hot does a cfl get? the plant does good under cfl so.........
