About Jack Herer
A Dutch sativa hybrid named for the author and campaigner, and one of the most-copied cultivars of the 1990s.
Jack Herer was built to carry Haze character on a shorter flowering cycle, using Northern Lights and Shiva Skunk to bring the schedule under control.
It has been reproduced so widely and by so many breeders that material sold under the name varies considerably.
