So i wanna scrog with this baby. I've heard that it is an awsome little gal to work with under micro-grow conditions. I've got a 400w hps for flowering and im gunna put her in a cool tube under a parabolic.

I have about 6 foot height of grow space limited to about 4 feet by 2.5 feet width and depth.

How high do i need my screen? I was thinking of putting her at about 24". Any ideas people???
