can i put my 2x400's in a 4x4 tent?

i have 2 aircooled 400w hps' just layin around....i was wundrin if i could run both of 'em in a 4'x4' grow tent...


my idea was to have both lights be connected and exhausted by a 6" or 8" inline fan...(cooltube style), and have a seperate carbon filter exhaust for the tent....



sound good? or should i just sell them and get a 1,000w?

Yep, I have 3 600's in a 4x8 although I think 2 1000's might be better for more penetration.

never mind....
