Intakes are two Doran 8"x8" darkroom louvres, one on the left side of the cab at the bottom, and one on the back of the cab at the bottom left. Outtake is at the top into a carbon filter. It doesn't rattle and shake at all, although the fan is certainly audible. Cab is 47"wide x 72"high x 20"deep. If I have the 400w light on and the eight 30-watt warm CFLs on too, temps top out around 10 degrees hotter than the room (which I keep at around 72 during the warmer months, and as low as 65 during the winter). If I just have the HPS on, or just the CFLs on, then the temps get to about 5 degrees hotter than the room. Yield is ~1 pound every 10-ish weeks.

And yeah, you're overflowing your closet there! Lol, but hey, better to have too many than too few! Any calyxes on the grown plants yet? You can tell sex without flowering, generally, if the plants are old enough, from the pre-flowers. Could be you'll be able to determine sex from some of the mature plants before the clones tell you.

Hope you have a bunch of nice healthy females! If there's a lottery, I'm going with 6 females.
