Well Cannabis Indica has been traced back to Afganastan. This in the beginning was the only place this grew, all other places where it grows now were put there by some man made means.

Cannabis Sativa started most people think around Durban in Africa, this is where the Durban Poison comes from. All other Sativas have there origin in this original variety. This is why we always use the terms Indica (originating north of the equator) and Sativa (originating south of the equator). This is why Indicas are darker green than Sativas because Indicas originated north of the Equator where they needed to produce more chlorofil (spelling). This chlorofil is what make plants green since Indicas get less sun they needed more of it. This was fun thank's,
