I don't understand how you can say it is 21% THC?? The potency of each plant is different, depending on how it was grown, etc.... At least that's what I read in a few different places. =/ Plus I don't think it was called AK 47 because its grown in Afghanistan, considering you could buy the seeds and grow it in your bedroom.

anyway, here's some info on it
