I am growing in a tent of that dimension with a 600hps cooltube setup. Works like a charm. Have 5 plants in it but will go up to 8 soon.

You can check my log out if you want, its in my sig.

Puffzter Reviewed by Puffzter on . Thinking about getting dr120, have a quick question Ok, was gonna hang panda, but thought the dark room would suit me better. My question is, the dimensions are 3'11 x 3'11 x 78, would a 600 hps do this, or would a bigger tent be better. Not sure how much a 600 will do. Probably be doing six plants in 5 gallon pots, what do you experts think? Rating: 5
