i wanted to ask can you lst train and then put the screen on top then or am i doing this all wrong? I was thinking that was how you do it but after reading many posts i dont think you guys are using any screens at all. Am i making a mistake doing this ? Because i have been lst training my ass off so far and maybe doing this all wrong .Because i was reading a guy got a pound off of 4 plants easy with a scrog .But from reading here these are two whole different techniques of growing dam !!
