I wouldnt go on just THC percents cause there is really no accurate way to tell. They are all just estimates and can vary based on the grow conditions. Besides, if you get a higher potency strain that is harder to grow you could end up getting less THC than a less potent with easier growing. Also if you get something wiht more yield you could get more THC total in the long run. I would look at numerous factors not just the percentage.
