Mate what a great read love your direction on this .and love the text from zamilto
When I traveled India I noticed even in the hot flat lands , wide leaves and very narrow leaves , when I say wide I mean wide ish def not sativa but not full indica , and then there was one In between not so wide not so thin ,
All three strains grew side by side , you would assume all were different phenos of the same verity , which they may well be , what I noticed and was told by locals was the short one flowers and finishes well before the tall one flowers and finishes , and the mixed looking pheno goes either way mixing with both .
I just find it increadable in the heat plains of Punjab short for sure indica dom plants grow side by side to sativas and never mix such is the diversity of our ganja .
Afghanistan used to also be part of Punjab . In India there is so much wild weed I could not imagine it originating from any where else to be honest .
