Jack Herer — Black Skull Seeds


  
Jack Herer is a legendary sativa-dominant hybrid named after the famous cannabis activist and author. Originally bred from Haze, Northern Lights #5, and Shiva Skunk, it was designed to combine the cerebral high of a sativa with the faster flowering and resin production of an indica. Black Skull Seeds’ version has been carefully selected for faster finishing phenotypes, completing in just 50–60 days of flowering while retaining the classic Jack Herer qualities that have made it a global favourite.
