Help with grow room

[Psion]

damn i think ventilation will be the hardest part, how would i have a fan sucking air in from under the door i dont see how that is possilbe, the only idea i have for ventilation would be to go the the right of the door as far as i can go to the corner of the room so the bottom of the stairs and take out a small square hole and put like a vent there.

I was assuming the door does not rub on the floor and there would be a space there that you could suck air through. If not, a hole in the wall works. I have 3 of them in my grow. And if you use HID, ventilation is by far the hardest part of getting set up right, especially if you want CO2. If you use fluoros, not so bad.
