1000hps scog !!!! that's gonna be a bitch to get off the screen! i thought my 400hps was a pain to cut loose. i suppose that is not a real problem though. the longer it takes the more bud you have! i really try to keep my plants to 6-8inches above the screen although around the perimeter i let them get a little taller so they can get better light . if you look at the pics of my current scrog you can count over 150 tops!
