Please help. I'm in the process of setting up my grow area. It's a small closet about 6'x3'. I have been doing as much research as possible on scrog/sog and I still don't understand a few aspects. 1.) When do you install the screen? 2.) How far from the grow medium should i install it? I've heard 1 foot, 2 feet... 3.) What is the best material to use? I've read and heard that hemp rope is good, chicken wire, and also thin plastic rope and even high test fishing line. As the material for the wire goes, does hemp rope or other natural cotton rope have a higher mold danger? And also is this method worthwhile since i'm going to try to squeeze 4 plants into this little area. And if it helps answer the question, I'm using 600w hps/mh.
