Thanks turtle for savin me some time lol,no hijacks here, feel free to comment. Cyclonite, everything turtle said is true. But to get huge yeilds out of the scrog you have to have a sativa dom. strain. The sativas will strech and strech so youll have to train them more but once you see the preflowers climbing up the stem, let em go. The screen is only there for a even canopy. The more even the canopy, the better light consentration=Bigger Yeilds
