Alright, so I have a cardboard growbox 3'x2'x3' which I'm assuming is 6sq/feet total. I'm only going to be growing about 3 or 4 plants of northern lights or white widow. From what I've researched, 5000 lumens is what I need per square foot; so 30,000 lumens total. I want to use cfls so the electric bill is less and so there isn't extreme heat. Is there ANYWAY I can do this, or is there a best and cheap way? Am I going to have to use hps lighting? I have 2 comptuer fans built in (1 for intake, 1 for out) so far. Will this be enough ventilation for cfls and hps?
Need grow box lighting and venting help please.

Well, with a box that small, it's going to be hard to go with HID. You may have to stick to incandescent bulbs, unless you can find a fluorescent that will fit.
With a box that small, I think that the computer fans will work decent. Heres a tip, put the bulb in there and see how hot it gets with the fans on. You want to aim for around 80 degrees.
thanks man. how many lumens are you getting out of 400w? what bulbs should I use? I have more fans so I'll accomodate.
