Jack Herer is named after the pioneer of cannabis legalization and also author of “The Emperor Wears No Clothes”. This multiple award-winning strain enjoys legendary status. The original Jack Herer strain was developed by Sensi Seeds. Nowadays you can find it in almost every seed bank, or at least their own variation of this famous and sought after strain.

Jack Herer: Top Strain As Tribute To Cannabis Warrior

He was a legend, a Legalize-it warrior, a cannabis campaigner…. Jack Herer was as real as it gets. To commemorate his achievements for the cannabis culture, the breeder of this strain created the perfect cross that will live up to Jack Herer’s legacy. This cross is, of course, named Jack Herer.

The ancestors of Jack Herer are Haze and Red Skunk. By the way, we mean the ancestors of the species, not the person, although it would explain some things. Red Skunk stems from the classic Skunk. Haze genes come from California, where growers during the 60s to 70s mixed the highest quality sativa landraces. They collected strains from South America, South India and Thailand. The genes traveled to Amsterdam, and ended up in the hands of many breeders.

This most often 60% Sativa-dominant strain delivers a complex high, including body stoned sensations, along with cerebral highs. It’s a long-lasting high, so clear your schedule – you’ll be goofy for a while. With its high THC content, you can expect true power. It reaches a medium height and enjoys SOG and ScrOG methods.

This plant is an absolute delight. You will see it develop from seedling to a mature plant, and you will become attached to it. Enjoy Jack Herer, and revel in the delicious highs. The amazing, uplifting nature of Haze will reveal itself after the first sip. The breeder did not mention any awards for this strain, stating that there were “too many to mention.” Jack Herer is an absolute classic, known to cannabis connoisseurs around the world.

Jack Herer Characteristics

The original Jack Herer is a balanced cross (50% sativa, 50% indica). The seeds are only available in a regular version. But nowadays you can find many different versions of the Jack Herer strain, each of which are slightly different from the other. However, they all have one thing in common: the enormous power.

  • Genes: 50% Indica, 50% Sativa
  • Parents: Shiva Skunk #1, Northern Lights #5, Haze
  • THC: 15%+
  • CBD: Average
  • Flavor: Fruity, Skunky, Pine, Spicy
  • Effect: Uplifting, Euphoric, Relaxing

Jack Herer bears the name of one of Europe’s most influential cannabis activists: Jack Herer. She was created from a cross between Shiva Skunk #1, Northern Lights and Haze. She was originally developed by Sensi Seeds as a perfectly balanced 50/50 indica/sativa cross. But soon after, several other variations were created. These tilted somewhat towards the indica or sativa side. Still, sativa-dominant specimens are the most common.

Jack Herer develops a THC percentage that fluctuates between 15-20%. This depends on the phenotype. Which makes the Jack Herer strain quite potent. The induced effects are more cerebral than physical. It is therefore wise to enjoy the inspiring effects during the day.
