Yeah, I know there are a multitude of factora that determine total yield, quality, all that shit... Some of the details... Using ocean forest soil, Kool Bloom 0x10x10 for flowering every other water, used Nova Grow (7x4x10 ?) for veg cycle every other water... Plants were vegged to be about 28 inches tall...maybe 8 to 10 main branches... Lower one third of plants have been stripped, continually pulling off the little lower suckers... Plants are very healthy...This really is pretty much my first real successful grow, well first one with a real Hps light anyway... The three plants pretty much fill the entire tent up with no training at all... Hope the information helps... Oh, strains are Blue Dream, Hollands Hope, and Widow Bomb...
