arg youre right, ventilation is a huge problem right now. I have a vent that goes into the side yard in that room, but it's currently blocked by a reflector.

my plans are to build an exhaust fan hooked up to my Carbon Filter and an intake fan coming directly from the vent (with dryer hose)

both powered by 6" inline duct fans
I just need to get around to doing it..

OVER 2 FEET TALL NOW!
It's amazing, one of the plant's shoots from the bottom of the plant has shot through the canopy. it's like they're on steroids, they went from 3" stressed out clones to 50" monsters in under 1 month so far..

i'll take some more pictures of the development
