I been growing inside in soil off and on since the 70's and I pretty much have it down to an art.At least I am happy with it and get a good return for effort. I ventured into water farming in hopes of the (to me anyways) elusive 60 day finisher. For a week or two of less lights, I bout decided it's not worth it. More effort, more money, way more crap to worry about. I think I'll stick to manure, compost and peat. Way cheaper and no chemicals:joint4:
