Frigaultanswered grow question 4 years ago Im doing 16 plant in 3 gallon (9in wide) no training need. On floor fan installed at seiling.. negetaif pressure to get lower canopy growth.. sea if green. Could do up 49 for pheno hunt fast grow no branching one bud. . But anywhere from 9-16 plant is a sweet spot for speedy grow minimal training. I don't top, but use a technique that allows lower branching tocatch the top.. canopy id filled in 4-6 weeks.. you can aslo do 3-4-6 even 1.. but then it need time to fill in.. i go for 16 nice top with 4-8 side cola. No defoliation. Only removing suckers and popcorn befor they for and make a few clone on shortest lower branching..
