About Jack the Ripper

Jack the Ripper is a fast-flowering sativa created by the influential breeder Subcool of TGA Genetics, crossing Jack Herer with Space Queen. It produces a powerful lemon-lime citrus aroma with sweet candy undertones and delivers a sharp, intensely cerebral high that is euphoric and creative yet clear-headed. Its name references both its dagger-like mental edge and its (very) fast finish. JTR won multiple awards in the late 2000s and achieved legendary status among sativa lovers.
