hey, this is my first "serious" grow: have about 20 plants under 4 40 watts fluoros. DOing pretty good: Still everywhere i read i find out that almos no one uses that small amount of light for so many plants. I have them in some black soil, feed them water with little amount of nutes to keep them below the burning range... Now, i know im not going to have huge amounts of bud for plant, im going for the massiveness of the crop. so my main concern is this: Will a lot of plants match up against in 2 or 3 plants under perfect conditions in amount of yield??? Also know not to expect some cannabis cup bud type crop, im mainly tryng to avoid buying shit off the streets. Hope i made sense and have useful input. Btw, ive read a lot, just this is the setup i got, no point in wasting it for not being state of the art.... I think it might work, what say u???
