What Size Fan to Vent CFL's?

Peace Frog

I have all of the supplies for a new 24 gal rubbermaid growbox for seedlings. Basically, one half of the stealth growbox in the FAQ. I hooked up the light fixtures inside and have 4 100 equivalent 5500K and 2 2700k.

My question is what size computer fan will I need to vent the 6 CFL's? Is 120 mm the minimum or can I use an 80 mm? I would prefer 80 mm if I could simply because it would be easier to light-proof, but if there is any doubt that an 80 mm would not be sufficient, I have no problem using a 120.

Any advice would be much appreciated.

Hey Peace Frog
In my humble opinion, when it comes to ventilation, it is best to error on the side of too much, rather than not enough.

Your ventilation is doing double duty, not only to rid your space of heat, but it also introduces new, fresh air, and more importantly it replenishes the used up co2, with new co2.

So I would opt for either two of the the 80mm fans, or one 120mm fan.
