it wasn't all the tk crosses. I understand your angst. He answers me in one day by email, you should hollar at him. To my recollektion, he stated if you got the TK crosses at the Denver Expo dealio, they were ok, if by distributor, maybe not but I think he was replacing them. And the two mentioned were the east cakes and the dosido cross. Not sure who works generations of fems, usually its a cut reversed or stellar female, but im no breeder, I aspire to be a polyhybrid bottleneck closet grower chuckin so of a gun. Life's too short to of such stuff, imho. I'd hollar at him at his email tell him where ya got em and go from there. But yea of all the chems, the 91 is the most finicky to grow they claim.
