Well, as a federally licensed caregiver whether I personally grow the medicine I share with my patients or buy medicine from state or federally licensed growers, I must have it all tested for more reasons than one might ever imagine, and believe this or not, really none of them have to do with the potency. But in the last 5 years, since I received my federal license I have personally tested 19 different auto strains for many of my patients which I have also personally helped them grow, and through all those adventures I have never see one of those auto strains reach a potency level that is even close to its photo counterpart, and in many of those comparisons they were actual autos that were directly bred from their photo mama, so they also came from the same breeder that originally created the photo that the auto came from. And in comparing most of those autos to their direct photo counterparts, the auto were always between 15% to 30% less potent their photo counterparts! And he is a few comparison results I have in front of me....
