Appreciate the help. I figured that might be the best approach, trying to save some $ by rigging my own setup, so I'll look thru my old crap.

Keep an eye out for my first ever grow log!
all4me Reviewed by all4me on . Computer fan ventilation So I am building a 150 watt HPS grow box out of a huge cardboard box, the inside of which I have painted white. I'm only looking to grow 2-3 plants so the space seems perfect (~2x2). My question is about making efficient ventilation. I was going to build a PVC tube to run just above the light with holes drilled to suck the heat out. Obviously the one end would be sealed with the other end containing some kind of fan, with a mesh covered hole at the bottom of the box just at stem/root Rating: 5
