Aloha everyone, stooked to get on here. I have been out of it for awhile and now trying to get back into the love of growing girls. I was thinking of getting the GL120 so 3'11*3'11 by 6". With a daystar 600w hps/mh conversion bulb and the rainforest 66 to grow 6 to maturity. I might get the RF another time but my question is could I just build a box out of wood to fill thise dimensions? Is it worth it to buy a grow lab? My neighbor is a carpenter so figured we could build it nice and cheaper. well thanks for your input.
