I'm looking for advice on a grow box. The one that I am converting is 4' wide, 2' deep, and 2' tall. I was thinking of splitting it down the middle and having a veg and flower chamber. Clones and seedlings will be in a small bookshelf on the side. That makes two 4 square foot chambers, but they are only about 2 ft tall. I have a 175 watt 6500k metal halide I am thinking of putting on the veg side, and a 150 watt hps for flowering. I might put 4 14 watt 5500k cfl's in the flowering chamber along side the hps. I thought that about 4 plants scrog style would be about right. Is there anyway that a 2' tall cabinet will work? I plan on using soil. As far as venting goes, I have a 4" inline ducting fan coming out the back at the top of each chamber. Not sure if I need intake fans, but i'm sure i'll need a few computer fans inside for air circulation. Do I need a cooling tube? Any thoughts at all on the subject would help. I'll try to get some pics up soon.
