2. Genetics and Lineage
Jack Herer is a sativa-dominant hybrid (approximately 70% sativa / 30% indica). Its pedigree represents an exquisite tripartite combination of three foundational cultivars, each contributing distinct morphological and pharmacological traits:
| Parent Strain | Primary Characteristics | Contribution to Jack Herer |
|---|---|---|
| Haze (Sativa) | Long flowering window, soaring cerebral lift, complex terpinolene-rich bouquet. | Provides the soaring, euphoric head-high, tall slender architecture, and bright herbal-pine aromatic notes. |
| Northern Lights #5 (Indica) | Rapid flowering, massive resin output, serene soothing body effect. | Supplies structural density, shortens the flowering cycle, and dramatically elevates trichome coating. |
| Shiva Skunk (Indica-dominant) | High potency, vigorous growth, pungent earthy musk. | Bolsters overall cannabinoid concentration, adds calyx firmness, and imparts deep spicy undertones. |
Lineage Notes: Although Haze originated from a blend of landrace sativas (Mexican, Thai, and South African), the Haze phenotype stabilized in Jack Herer represents a carefully selected commercial line. Both Northern Lights #5 and Shiva Skunk are elite hybrid building blocks, creating a remarkably stable F1 foundation.
