HydroRed’s Blue on Black is an F1 cross of Purple Power and the Indica dominant hybrid Blueberry Hashplant, also known as “Hash Berry.”

A hard-hitting Indica by Cool Creek Genetics called “Purple Power” plays the mother role in this blend of unique flavors by being crossed with a keeper cut of Bodhi’s perfectly blended “Blueberry Hashplant”. Unique terpenes & couch locking potency are in abundance with this one! Both parents in this cross are producers of heavy flowers. You can anticipate big yields of heavily frosted flowers that range in smells from floral incense to sweet plum wine & spices making this one immensely appealing to those who prefer something different than “the norm”.

Available in Feminized seeds only.

Recommended flowering time: 60+ days

7 Feminized Seeds per pack plus freebies!
