Jack Herer Auto feminized seeds deliver a sativa-dominant autoflowering cultivar built for consistent performance and clean cerebral effect. Finishing in 60 to 70 days from germination, this strain combines the uplifting character of the original Jack Herer with the compact cycle of ruderalis genetics, producing 16% THC and 0.5% CBD across a plant that stays manageable indoors and outdoors alike.

Genetics & Lineage

The lineage here is Jack Herer crossed with a ruderalis, preserving the sativa-forward structure and effect profile of one of cannabis breeding's most well-regarded photoperiod varieties while adding the autoflowering trait for light-cycle independence. Jack Herer itself is a three-way cross involving Haze, Northern Lights #5, and Shiva Skunk, giving this auto version a genetic foundation that leans strongly sativa — estimated at around 60 to 65% sativa dominance. The ruderalis contribution is functional rather than flavour-forward, influencing the automatic trigger and compact stature without significantly dulling the effect ceiling established by the parent genetics.

Aroma, Flavour & Effects

The terpene profile reflects the Haze and Skunk ancestry. Expect a sweet, resinous base cut through with distinct black pepper and spice notes — the peppery quality comes from elevated caryophyllene, which also contributes a mild, grounding counterpoint to the more stimulating terpenes. Pinene and terpinolene are likely secondary contributors, adding a faint piney brightness and slightly floral edge that rounds out the inhale.

At 16% THC, the effect sits in a reliable mid-to-upper range — strong enough for experienced consumers to find genuine potency, approachable enough for newer users who understand their tolerance. The onset is relatively quick given the sativa dominance: expect a clear-headed, focused elevation that sharpens attention without heavy sedation. The 0.5% CBD content is modest but may soften any edge for sensitive users. Duration is moderate, typically two to three hours before tapering.

Growing Profile

Indoors, Jack Herer Auto grows to 90 to 100 cm, making it well-suited to standard tent setups without aggressive height management. Yields land between 400 and 500 g/m² under optimised lighting — achievable with a quality LED or HPS setup and proper VPD management through the grow. The full lifecycle from seed to harvest runs 60 to 70 days, which is genuinely fast for a sativa-leaning strain of this calibre.

Outdoors, each plant produces approximately 200 g in a single run, and because flowering is triggered automatically rather than by photoperiod, growers can run multiple cycles across a single season. The strain carries solid resistance to common fungal diseases and handles moderate environmental stress with reasonable resilience, which gives it practical value in less-controlled outdoor conditions. Low-stress training techniques such as LST or light topping early in veg can improve canopy spread and light penetration, translating directly into yield improvements indoors. No advanced techniques are required, but they reward growers who apply them.

Who This Strain Is For

This strain suits growers who want a fast-finishing, sativa-effect plant without dedicating a full photoperiod schedule to it. Beginners will appreciate the disease resistance, compact size, and straightforward feeding requirements. More experienced growers running perpetual harvests or maximising outdoor seasonal windows will find the 60 to 70-day cycle and consistent output genuinely useful. Consumers who favour daytime use, creative focus, or mood elevation over sedation will find the effect profile well-matched to those needs.

Five feminized seeds per pack means every seed has a direct path to a productive, flowering plant — no males, no guesswork, and a genetics profile that has earned its reputation over decades of cultivation.
