Jack Herer strain is one of the most iconic cannabis strains in the world. Named after the activist and author who fought for legalization, this strain has been around since the 1990s and continues to shine in 2025.
It is a sativa-dominant hybrid loved for its uplifting, creative buzz and smooth body relaxation. It's won multiple Cannabis Cups, been used as a parent for countless hybrids, and remains a top choice for both recreational and medical cannabis users.
Jack Herer Strain Genetics
Jack Herer was created by Sensi Seeds in the Netherlands. It’s a three-way cross of Haze, Northern Lights #5, and Shiva Skunk.
- Haze delivers the soaring cerebral effects and creativity.
- Northern Lights #5 adds resin production and gentle physical relaxation.
- Shiva Skunk contributes density, stability, and flavor.
The result is a balanced hybrid, usually 55–60% sativa and 40–45% indica, offering stimulation without anxiety and relaxation without sedation. Unlike an indica dominant hybrid, which tends to produce more sedative and body-focused effects, Jack Herer leans more toward sativa effects, providing more cerebral stimulation and less sedation.
Jack Herer THC Percentage
Jack Herer typically tests between 15–24% THC, with premium grows reaching 26–27%.
CBD is usually very low, often below 1%. This makes Jack Herer a medium-to-high potency strain that can satisfy experienced users but is still manageable for beginners when consumed in moderation.
