Hello. If you go to the breeders page and look up your strain. When you scroll down and see all the crosses that go/went into making of your strain. You must realize that each one of those mixes can put some genes into your strain. Yes. some breeders go to great lengths to breed out the unwanted traits. Even the best breeders will have some variances in their plants. Such as difference in taste and bud size and stretch when flowering. When I use regular seeds I can usually see a bigger difference in traits. Good luck Chuck.
