I think so, I dont have a ventilation system yet. during the day the door open there are two fans (one really high up blowing outwards as a ghetto make shift vent fan) and one ocilating on the plants. For the last two hours I have to shut the door. I plan on installing a ventelation system, but I have to buy another door to tare up.

I will say, I could'nt afford a ballest to go with the 125w grow light, and had been putting mylar over the top to create more reflection and I think it could have also been causing even more of a heat problem. I just stopped doing that and it kind of looks like they bounced back a little.

I'll post pictures tonight.

thanks WH.
