As far as i know, medical grade [From the club] is just as expensive, if not more expensive than buying off the street, but at least you know it's superior smoke. But it's easier, and cheaper to grow. Well, maybe not easier, but it's ALOT cheaper, and it gives you an amazing hobby that you'll never get out of youe system. Like when im not growing, i feel lost as though something's missing form life, so that why as soon as i harvest i get more seed germinating. Got some going right now. I got a another few 90% sativas [My own strain] and i got a few indicas, hopefully then i have a nice choice.
