I can't help but think that if you had good genetics and the grow went well, there has to be something amiss here. The first thing that comes to mind is your dry/cure method.
I dried some up to fast and I was disappointed, in the smoke, taste, potency, across the board. I reevaluated my drying method and slowed it down. Simply put, I now have some of the best weed in town.
Autos get a bad rap from hard headed people who tried it when it was just taking off years ago, I think. There are plenty of old skool, and new skool alike, who are soaring from auto highs. They've come a long way.
That sucks your first go at it was disappointing. I have yet to smoke Mephisto. But seriously, how can this many growers be wrong. Not 1 single complaint I have seen. I can't wait to see what kind of high Sour Crack gives me.
Peace
