lol you could always stick to the amount you are growing SL just use sh*tloads of lst fimming/topping keep them short and bushy,Ihave no doubt that 4 plants in my tent lst'd will fill it with no problems.Me personally would rather a short bushy plant,i wish i had used LST more on my babies as they are growing fast,the biggest one now is 21 1/2 inches i measured them wed and were 18 inches,still got the stretch to come from flipping to 12/12 in 9 days :-D
