In my own chase of my first "high," sativas, have come the closest. I did not personally witness mexican genetics shift in mexico, but I believe in change, so if indeed mexican brick changed in the new century, then I am also very curious as to how indica evolved in areas where sativas once flourished. I personally believe that genetics overpower environment, but itsrarely that simple. Nonetheless, Iam a fan of the 90's Chi-town stressand have no problem growing seedwhether it be bought, free, bread,or accident, white, black, solid,striped, small or big, I even grow the red tinted ones ;^}
