THC: 31.0% CBD: 0.21% This mostly indica strain is a mix of Afghani and Blackberry strains and has beautiful dark purple buds with orange hairs. Plants will flower at 7-8 weeks and are not particularly high yielders, but the dense, hard nugs have crystals throughout. Blackberry Kush tends to have a hashy, jet fuel smell and taste that is balanced by sweet berries. Blackberry Kush is often recommended for the treatment of pain thanks to its strong body effects.
