What Is The Jack Herer Marijuana Strain?

Jack Herer Strain Genetics
Bred by Amsterdam-based seed bank, Sensi Seeds in the mid-1990s, Jack Herer is a balanced hybrid strain with a slight sativa lean. Its genetics have remained unconfirmed by Sensi Seeds. It’s widely accepted, however, that Jack Herer’s genetics are a cross between Skunk #1, Northern Lights #5, and Haze strains.
Regardless of the mystery behind its genetics, Jack Herer has amassed a record number of industry awards around the world. For over 20 years, it has been a staple among the cannabis community. This strain has even earned approval as a medical-grade strain by Dutch pharmacies.
Because of Jack Herer’s complex three-way lineage, the strain produces four distinct phenotypes. Three phenotypes lean toward sativa characteristics, while one indica phenotype produces taller and denser yields.
- A: Stringy buds, large calyxes, and highly potent. This Jack Herer phenotype can grow excessively tall unless flowered when it’s very small.
- B: The most indica phenotype of the Jack Herer lineup. This phenotype is compact, a fast grower, and produces a strong yield. This strain has some indica-leaning effects without overpowering the cerebral sativa effects.
- C: This one’s similar to phenotype A in many ways, but tends to grow smaller calyxes that look like spikes poking through the buds. Phenotype C produces a heavy coating of resin, which provides the most amount of energy out of the Jack Herer phenotypes.
- D: Phenotype D is a good option for home growers due to its high resin production, but may not be right for commercial growers due to the strain’s quick growth spurt during flowering leaving gaps between nodes at the top colas.
