This will be a no till grow, utilizing mulch and enzymes and attempting to mimic a real life natural soil. There's a fella on another site's organic section who I'm trying to emulate and he recommends 20 gallon minimum in order to give you room to work. His results speak for themselves and honestly, the whole layers of mulch decomposing naturally, untilled, worms, microbes, fungi and all, working together in a symbiotic relationship without much if any work kinda turns me on. Makes me wanna grow my hair long and get nekked. Lol.
