I'm planning on growing in my closet. The grow box I build is 2'4" deep, 5'4" height, 2'6" width. I want to grow 4 plants. I'm going to use a 400w HPS light for the whole grow (this). I'm sure I will need ventilation, so I'm going to be putting 2 80mm computer fans on the top (outtake) of the box, and 2 on the bottem (intake). Any suggestions? Thanks
Looks good.. Also try not to think of ventilation only for Cooling the plants need it even more so for proper air circulation.
