I agree with the other posts.

Im very new to this growing but from the time ive spent looking at various posts and websites i would say air flow is VERY important.

I have invested two 5" fans pumping/ducting in fresh outside air into my grow and i also have one 16" fan inside moving the air around too.

I dont think you can ever have to much smoke eeeerrrrr i mean air :rastasmoke:
