Dark Star OG is an indica strain cross between Purple Kush and Mazar-I-Sharif and OG Kush. Dark Star OG is  dark green and at times some purple strain was first bred indoors by T.H. Dark Star effects are as spacey as its name suggests: a deep, relaxed sensation throughout the body accompanied by a heavy cerebral calm. Though celestial in its effects, the strain is more likely homage to the Grateful Dead’s song “Dark Star.”
