Jack the Ripper


aka JTR


Jack the Ripper (JTR) has been slaying fans since TGA Subcool married a Jacks Cleaner female with a Space Queen male to create what some say is the best Haze strain ever.

Amsterdam Seed Center says JTR has extreme THC content, more than 20%, low CBD, resin-rich buds, and a citrus aroma with lemon mango flavor. One of the phenotypes smells more woody. JTR is a potent strain with an uplifting, sometimes heart-racing, effect.

The killer strain was on High Times Top Ten List in 2006 and won second place at the Spannabis Cannabis Champions Cup in 2017.
