yah, i try to stay away from banks that sell say white widow or northern lights, but then don't list a breeder for said strains.. this is red flag number one that they more than likely aren't very legit.. and buying fem'ed seeds from such a place is a complete waste of time from my experience..
stick with known banks that sell reputable breeders gear, and you'll never be disappointed..
places i've used and like are in no particular order
