Lol so your saying if you have plants growing outside and they are packing on some weight and it rains everyday for several days and no sun with its very humid, it makes you a terrible grower when they will get moldy.
Dude all your doing is just hating. No matter what I could say or do it would never be good enough. You would just put it down. Your very bitter.
Moldy? WTF are you babbling about? Your "stadium grow" is stacked full of plants that are either suffering from some kind of nutrient deficiency or burn, or they are having PH issues. You're claiming some other large size grow room but have no pics, but that claim doesn't really hold water as you stated early in the thread that you're "dabbling" with indoor. So which is it?
You're all over the place and need to get your stories straight. Based on the one pic of that super sweet stadium grow, I'd say that 12 pounds per month is a fantasy for you. And the fact that you had to post this question in a weed forum, rather than simply draw up plans and do the math, is another indicator that a 12 pound a month setup is not in your wheel house.
