Jack Herer from Green House Seeds: A Timeless Classic

Jack Herer is a feminized photoperiod cannabis strain developed in Amsterdam by the Greenhouse Seeds Company – purveyors of award winning, world class cannabis genetics. This strain needs no introduction – this sweet and pungent Sativa-dominant cannabis strain with up to 21% THC is one for the history books!

Growing Jack Herer is a pleasure – those who are experienced and comfortable with pruning and other high stress training techniques will really be able to push this strain and their growing skills to the next level. Indoor growers can reportedly get up to 800 g/m2 of dense, sticky buds after a short 8 week flowering period. Outdoor growers can pull a whopping 1.2kg/plant at the end of September. Here is more information to help you grow this strain:

  • Medium height – due to her roughly balanced Sativa:Indica composition, Jack Herer grows to a medium final height.
  • Max EC of water – 1.4 in veg, up to 1.8 during flower.
  • Water pH: 5.8-6.0.
  • Ideal for SCRoG – her strong, yet flexible branches and medium height make her perfect for ‘screen of green’ style grows to maximize yields.

Pleasant and Uplifting

Jack Herer has a very distinct smell which can only be described as pleasant and aromatic, with hints of citrus in addition to her pungent cannabis odor. Her uplifting effect is due to a Sativa-dominant genetic lineage, which makes her a favorite among those looking for a boost of energy and creativity during the day.
