I grow in a green house. I useually have 6-8 plants growing at once in 3 levels. I use a small amount of topsoil, peatmoss, and amonia nitrate. With this type of growing I usually never run out. What would be the best way to grow less plants and have just as much bud with out completely changing my set up? Another question. My bud is usually somewhat harsh at times. Could this mean i'm using too much amonia,or just need to add something else? Thanks for your time.
