Tactically if your going vert. Drop a naked 315 in the center of 4 plants. Use all the bulb and get a bumper crop. If your gonna Scrogg do two plants and get a cob and still get a bumper crop... I'm biased to the first option but style will weigh heavy on this decision. You won't loose either way. As many opinions are out and both techs are solid. Both will get you great meds both have an entry and learning curve and with that space allotment your style may be predicated on budget. I've seen the cob stuff do some pretty amazing things and like a lot of the old timers still a little hesitant to pick up the new hammer... happy growing..
