what are you growing in

soil is what i grow in if thats what ur lookin for and also its in my closet

I grow organic in soil. I don't flush. I just feed a nitrogen fert during veg and a P&K fert during flower. I let the genetics do the rest. I don't pamper them. I don't do any LST or bending or cropping or any BS like that. I also don't believe in adding "beneficial fung" unless your growing in test tubes. I keep things stupid simple. The key is to start with good seeds or clones. Everything else is just about keeping the plant alive.
