Yeah but we're all different. Mine is for personal pain relief and 2 grows a year does me fine for that. I never sell or give any away and only smoke before bedtime. It just keeps me off the codeine and morphine-related pescription drugs. Spent too many years on them and they f@@ked me up. That's my only aim. My legs are more metal than bone. I don't grow for profit and make a point of never selling any of it (my ex had ideas of it. What, that's my medication?). Maybe it's just me but it is me. I have nothing against anyone else doing their own thing but I grow what I need for my own needs and a 600w, 2 grows a year fits perfectly. No more, no less.
Still, each to their own.
