Pure Breeding’s Cotton Candy Rock Candy is an F1 cross of Durban Poison Bx and New England Rock Candy.

You can imagine how this turned out! PB took an absolute stunner of a Durban Poison out of his original Durban Seed lot and backcrossed her to the original Durban mother that he had to lock in all the blueberry and cotton candy flavor you could want.

Pure Breeding then took his New England Rock Candy breeder cut that tests at 30 plus percent cannabinoids and dusted her with all the Durban pollen he could, creating absolute GEMS. These girls are 100 percent connoisseur flowers packed with flavor. I highly suggest grabbing these while they last!

Be advised, that PB did the best he could to remove all hermaphroditic traits from this genome, but this does not mean it is 100% herm free, there are always outliers when it comes to breeding and biology.
