Black Belts Feminised Cannabis Seeds – Archive Seedbank

Black Belts by Archive Seedbank is a powerful hybrid created by pairing Oishii #9 with the highly respected Rainbow Belts #20. Both parent strains have made a significant impact on modern cannabis breeding, celebrated for their intensely candied Zkittlez-style terpenes, floral potpourri notes, and unmistakable OG Kush undertones.

Despite both parents having balanced profiles, their combination surprisingly amplifies the OG Kush influence, bringing stronger expressions of gas, petrol, sweet diesel, and a thick, expansive smoke. This results in a cultivar with far more OG character than one might expect from the lineage alone.

While rare phenotypes can lean towards heavy candy Z terps, most expressions present as gassy, pungent, and deeply aromatic, complemented by vibrant colours and rapid flowering times of 8–10 weeks (56–63 days). The smoke is exceptionally flavourful and produces a potent, long-lasting high that is not recommended for beginners.

Black Belts is a strain for skilled cultivators—those who have earned their “black belt” in the grow room. When handled with experience and precision, she rewards growers with connoisseur-grade flowers and elite potency that stands out in any collection.
