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?

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.
