Can I put a 600w hps or 100w hps in a 32x32x63'' grow tent?

its about heat... if you have good airflow 1000w is ok.

 

So how r they doing?

 

Gotta get that hood properly cooled though. I suggest a dedicated line to pull cool air through the hood, and then out the tent. then a second line to exhaust, and circulate new air into the tent. 32x32 might be tough, but I have done it with a 4x4 room with less head space. I pull winter air from the outside straight through the hood though.
