Of course I would use PVC elbows and what not to make the light traps by vent holes, but I was just curious if that would work, and also how often would the vent fan need to be on??
If I was to stick with the CFL's, what about a box that's 2' wide by 2' deep by 4' high? Do those sound like reasonable dimensions? And could I only grow one plant in a box that size or more?? Please lemme know because I've already germinated my seeds and I don't want to put off the build too much longer...thanks!
I vegged a grow like this and am now flowering. I used a simple cardboard box and my plant is a beast. I also used CFL's.
