ok, so i just need some help with this, i have a rubbermaid bin with 2 holes on the back, one with a fan blowing in, all inside painted flat white. The bin is 3' tall has 3ft squared room, with (3) 42w CFL lights (2700 lumens e.a) which would give a total of 8100 lumens. If i place 3 clones in them to grow to about a foot tall each would this be enough light to keep them growing fine? ( Iam not expecting monsters, just to grow three babys into one foot tall clones that will then be moved into a seperate room and i just want to know if this will be good enough to do the trick or what I would need bare minimum for now)

Maybe think about those fans a bit more.
If your venting hot air to the back and that's where your fan is, then your fan will just suck that hot air back in.
Also it's more important to get the air out than in. Try turning your fan around and sucking the air out. It will create a vacuum so cold air comes in to fill the void.

with this many watts of cfl lights they wont produce that much heat though. Mine have no problem overheating with a little 6 inch fan i paid 5 bucks for from wallmart blowin on my two plants and just circulating the air, mind you i do have it set up so fresh air can get in.
