    you will need a fan for wind, and one for exhaust I hope this helps

    yeah, they need wind to get strong, and not stretch so much, and exhaust to control temp etc.

    Im running cfl's as we speak and from what i've seen is you need to have a good exhaust but you might can get away with no intake fan, a passive intake.

    Just a quick q... I'm using 4x40 5000k(best I could find) and planning on two plants...reason one being I'm starting from seed not to keen on growing one and getting a male... NY question is...is it enough from the pictures you can see? Also...I'm thinking about going to purchase a couple 20w 2700ks for flowering...but chucking them.in for the full grow... What do you guys think ?
