Description

Sir Jack

Sir Jack is the exclusive feminized S1 version of the legendary Jack Herer, created by self-pollinating a particularly resin-rich and aromatic mother plant. The plant delivers the characteristic Sativa high combined with a complex terpene profile that delights lovers of citrusy-spicy strains. Thanks to the stable S1 genetics, the phenotypes show high uniformity in growth, aroma, and effect. It is perfect for extractions and concentrates, as the buds exhibit above-average resin production.

Synergies

The terpene trio Beta-Caryophyllene, Terpinolene, and Limonene creates a vibrant synergy: Caryophyllene spices the base, Terpinolene brings floral freshness, and Limonene adds a lemony top note. Together, they ignite an awakening, mind-opening effect that encourages sociability and creativity.
