Not to much light, but i hope you have some good ventilation because your closet would be way to hot....
I will have 2 x 30litre per sec fans.
Have i got this right? im no good at maths
2x2x7 = 28cubic feet
1cubic foot = 28litre
28 x 28 = 784 litre
2 x 30 litre per sec fans = 3600 litre per minute
Would that be good enough for ventilation? or should i add a couple of vents into roof?

What he said...hard to have too much light...easy to have too hi temps...
Cheers guys, ok hard to have to much light but is my vent plan enough?

2 x 30 litre per sec fans = 3600 litre per minute
3600/784 = 4.5turn over per minute

my calculations say that fan is 64cfm...
30 * 60 / 28 = 64...theoretically yeah you are replacing the shit out of that air...you probably only need one...get a variable speed fan controller and adjust it as needed...i doubt you'll need to have it set on high if your intake is at the bottom and your exhaust where the fan is up top.

I'm gonna be running a dimmable 600 in a 2x3x7 closet. One thing I know for me anyway is it will absolutely have to be air cooled! I'm running a older 250 mH right now with the ballast attached and open hood and its still pretty difficult for me to control the temps. Thats with an extra a/c duct ran to my closet too. It really depends on ambient temp, when my a/c shuts off I'll be sitting between 90-93 and thats with a high powered 70 cfm computer fan.. Personally I'm running a 160 cfm inline fan to help cool the room, if you can get away with lower cfm fans then good for you but it might be a little harder to control then you think.
If thats turns out to be the case i shall install some extra vents/fans.
Thanks for heads up
