with CFL's there is no such thing as too much light! as far as circulation, it sounds like it will be fine. Very tight space for a newbie....good luck

thanks sirbudmaster, yeah it is kinda small but its just for personals, im gonna either lst or scrog them so hopefully it turns out ok, just kinda doing it for fun.

i think in that size space you will be better results in scrog.....LST tedious and in that size space will be challenging.

cool, thanks again, definatly gonna post pics once their done.

also wondering about a good/cheap way to keep light from getting in through my fans? i was looking at using midget darkroom louvers, i saw this on a pc grow the other day, just wondering about anyother methods, door screen etc. thanks.

are you worried about the light showing? or worried about dark cycle and light leaks during flower? for lights out you can simply hang a thick cloth down over the fans.....

im worried about light getting in during flowering, i would like to continue to run the fans while the lights are off though. where my box will be is a very dark area and there shouldnt be any light at night, should i just set my cycle to be dark at night?

will most likely be doing 12/12 from seed.

that would be best to cycle it along with your dark times at night.....pending your fan size, you can attach an "S" hose to it and run the air through it, the bends will stop light from coming in....this will however slow the fan down, so will have to make sure its oversized......
