Will I have a heat issue?

I know CFLs run cool but I've heard of people having some heat issues in real small spaces.
The box plans: 16x19x24"
Roughly 4.22 cubic feet of air space.
Growing LR2s.

I want to run 6 20Ws all around them and one air purifying 14w.

I can build taller but not much wider. Do you guys think I'll have a heat problem? What about if I put an 8" computer case fan in the base?

Also, pretty sure I know this answer, but I'm just making sure. Is it better to have a bunch of low watters (20w) or a few 42w and a 85w or higher.

Put the fan in. Should be ok.

I would bet that the you would ok as long as you add an exhaust vent at the top of the cab (remember...hot air rises). The only time I have run into a heat problem with cfl's is when I was using 42w+ bulbs. Under that a simple intake and exhaust vent should work fine.

Good Luck...

But I live with the mother and can't be venting fully matured LR2s. Even with the air pruifying bulb. Can I?

You tell us bro... More than two plants is going to create an odor to an non-smoker. Just the facts of life.......

Ah ha! I'm in luck! She smokes a bunch! I think a carbon filter will be able to control it, with the bulb.

MC - looks like your set up is pretty similar to mine. How is the smell when the door is closed?

pretty bad..... My cab was built to be more functional than stealth... i own my own home so I was just trying to make things work.
