Big Jack Cannabis Seeds Feminized
Big Jack is a feminized, mostly Indica hybrid with an undisclosed exact lineage, bred for a stable, high-yielding growth pattern. It tests at approximately 19–21% THC with low CBD, flowers indoors in 55–60 days, and yields up to ~800 g/m² indoors or ~700 g per plant outdoors, typically harvesting in late September. Plants stay compact indoors (120–150 cm) and can stretch to 200–250 cm outdoors in favorable climates. Reported effects begin with a mild creative and mental lift before settling into comforting Indica-driven body relaxation, without heavy couch-lock.
Genetics
Big Jack's full parentage isn't publicly disclosed, but its traits are classic modern Indica: dense bud formation, moderate height, a short flowering window, and a subtle Sativa undertone that keeps the high from becoming fully sedating.

Effects vary by person and dose. Not medical advice.
Reported Uses
Some users report the balanced profile as supportive for stress, mild tension, or difficulty winding down at night, with the early mental lift occasionally noted as helpful for creative tasks. This is not a high-CBD or medically targeted strain, and none of this is medical advice — consult a healthcare provider for medical use.
Growing Conditions & Tips
- Difficulty: Easy — minimal training required, though topping or LST can boost yields.
- Watering: Consistent, moderate moisture; avoid overwatering.
- Nutrients: Balanced N-P-K; watch for nutrient burn.
- Ventilation: Even small spaces need airflow to prevent mold on dense buds.
- Advanced techniques: Topping, LST, and ScrOG all suit Big Jack's compact structure and can meaningfully increase yield.
Harvesting & Curing
- Harvest timing: Late September outdoors, or 55–60 days from flowering onset indoors; check for mostly milky trichomes with a touch of amber.
- Dry: 7–14 days in a dark, ventilated space (45–50% humidity, ~20°C), with even airflow.
- Cure: Airtight jars, burped daily the first week, then less often over 2–4 weeks to develop the full lemon-sweet aroma.
