New Clone Box

Just built a new clone box and am just a little stuck on the intake and extraction. Ive just been looking into fans and got diverted onto a forum that said the computer fans will do little or nothing, would anyone agree or disagree??? Have sorted everything else just this one left to do now
Box dimensions are 130cm long, 60 cm wide by 75 cm high

Cheers

what lighting ar you using? I will assume something that does not emit much heat. a computer fan acting as an exhaust with a correctly placed intake near the bottom will give you good extraction. The amount of air being exhausted is = to the amount being taken in.

Hope this helps

I use CFL's for clones/vegging and computer fans keep it plenty cool.

all you need is a small fan for clones 50cfm or so cause it wont get that hot in there

Cool, nice one guys, u all seem to be saying the same kinda thing. The light im using is a exolux fluro light, designed for clones and mothers. My friend has told me where to get 240v fans from now as well
Thanks All
