Our take

Blackberry Kush is a feminized, photoperiod indica bred from Afghani and Blackberry genetics. It stands out for its layered aroma — ripe berry and blueberry up front, with a diesel undercurrent — and a 20% THC content that leans toward relaxed, settled evenings. At intermediate difficulty, it suits growers who have one successful grow under their belt and want to step up to a more rewarding harvest.

Yields up to 540 g/m² indoors after a 63-day flower cycle
Finishes outdoors in mid-October — workable in continental, Mediterranean, and sunny climates
Feminized seeds mean virtually every plant goes straight to flower, no males to identify and remove

Growing notes

Blackberry Kush flowers in about nine weeks indoors and wraps up outdoors by mid-October, making it a reasonable fit for shorter warm seasons. It stays at medium height, so standard tent setups work well. Expect medium to large, moderately dense buds. It performs in both indoor and outdoor environments given enough sun. Intermediate growers should focus on consistent feeding and good airflow to protect the canopy.
