i have grown out oz s from 2l bottles. usually average about 20-25 gs. not with those strains yet though, but nk knows what i run, but that is with 1k bulbs.NorthernKronic said:Idk to tell you the truth, really its all strain/grower/condition dependent. Ill probobly yeild about 7-8 grams realistically off of that 2L bottle. maybe even less but im still not sure...
