I did some research and couldn't find anyone who carried BioQueen seeds or blue diamond....same for Blue Zkittelz, but I saw Dying Breed around. Unless it was a dispensaries own cross, (a lot of them in the North East use their own clones and make their own strains) it doesn't look like there are any blue zkittelz seeds available. Dying Breed has some other Zkittlez crosses that may interest you.. a watermelon version, or maybe a Blue Kush might have some of the same effects. good luck on your strain hunt! 👊
