Around here, one plant, seedling to full bloom, constitutes one pound.
Off topic: There was an incident a few counties over where the law executed a search warrant at a drug house. One of the occupants rinsed an eight ball of meth down the sink drain. They cut the water or some shit and took off the s-bend. Charged him with water weight, everything they could get to test positive. Over 1200 grams.
Moral of the story: Cops can fuck you if they want to.
Secondary moral: Don't put your meth down the sink drain.
