Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-09-09 on 150 seeds.
About LA Jack Feminised
LA Jack announces itself in a fixed order, and caryophyllene is always first out of the jar — warm pepper that registers as heat rather than as smell, with dried clove and sandalwood beneath. limonene follows mid-palate, adding a bright citrus edge. The lab figure on this 62/38 hybrid is 24% THC, though potency is the least interesting thing about it — plenty of cultivars test the same and taste of very little.
The Aromatic Three
Leading with Caryophyllene, then Limonene, and Myrcene underneath.
Difficulty: easy. In flower for 60-70 days. Stands Small (0-120 cm). Indoors it returns up to 400 g/m2. Outdoors, up to 500 g/plant a plant.
