I just skimmed thru your whole post, wicked setup man. Makes me really mad, had 3 TVs that were 55 inch plus ones like that in our garage that didnt work. My roommates and I even joked about growing in them, but laughed it off thinking theres no way....
Anyways, had a question about your fans. They look like PC fans (exhaust and intake) are they working well, even through your carbon filter? Have heard a lot of people say PC fans are not strong enough. How much are your girls smelling now anyways?
