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 your growing skills to the next level. Indoor growers can reportedly get up to 800 gm-2 of dense, sticky buds after a short 8-week flowering period while outdoor growers can pull a whopping 1.2 kg per plant at the end of September. Here is some further information to help you grow this strain:


  • Medium height – due to her roughly balance 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 maximise yield.


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 odour. Her uplifting effect is due to a Sativa-dominant genetic lineage which makes her a favourite among those looking for a boost of energy and creativity during the day.
