that Scrog is still in progress "if"

im just bit worried that growing all 6 same time would pretty much take too much space. As lights as 2x400w and 1 120w LED and growroom in mammoth tent 2.4x1.2x2. I have thinked of keeping em in controll with LST em as down as possible. i have 1 mazarxrandom regular that i have been keeping as bit project. Mainlineing and supercropping and also LST.
Also i was wondering that does scrog even work on autos? As i was in that impression that you should not top autos.
