Jack Herer Auto Seeds

Genetics & effects

Jack Herer Auto is a feminised autoflower seed with a Jack Herer-type lineage, combining Haze, Northern Lights and Skunk influences with ruderalis genetics. Its estimated balance of 60% sativa and 40% indica supports a relatively compact structure while retaining the lively character associated with this classic profile. Outback Seed Bank presents this variety as an approachable option for growers seeking a quick-flowering, space-conscious plant.

THC is listed at approximately 15–19%, with CBD at up to 0.1%, although cannabinoid levels can vary between plants and growing conditions. Individual experiences may feel energetic, uplifting, creative or focused at first, sometimes settling into a relaxed, euphoric finish. Effects are subjective and may differ considerably from person to person.

The aroma and flavour profile may combine sweet spice, fresh pine and haze-like herbal notes. Terpinolene, myrcene, caryophyllene and pinene are associated with the listed profile, but expression can shift with phenotype, environment and harvest timing.

Growing in Australia

Jack Herer Auto is considered beginner-friendly and may suit temperate or hot, dry Australian settings. Autoflowering plants begin flowering according to age rather than a change in daylight hours, making timing comparatively straightforward. For a conventional outdoor cycle, spring planting falls between September and November, with seasonal harvest planning from March to May. Autoflowers may finish earlier depending on sowing date, local climate and plant development.

Use a light, free-draining growing medium and avoid keeping the root zone constantly wet. Stable conditions, moderate feeding and good airflow can help reduce the risk of stress and mould. Because autoflowers have limited time to recover from disruption, gentle handling and minimal transplanting are sensible.

Indoor

Indoors, plants may reach up to 100 cm. A consistent lighting schedule, suitable ventilation and enough space between plants can support an even canopy. The estimated indoor flowering phase is 8–9 weeks, though the complete seed-to-harvest cycle may be longer.

• Height: up to 100 cm
• Estimated yield: up to 400 g/m²
• Difficulty: beginner-friendly

These figures are reference points rather than fixed outcomes. Equipment, plant health, phenotype and grower experience all influence performance.

Outdoor

Outdoors, Jack Herer Auto may grow up to 120 cm and can fit balconies, courtyards or sunny garden positions where local rules permit. Choose a location with direct light, airflow and shelter from prolonged rain. In humid districts, inspect dense growth regularly and keep foliage away from wet surfaces to reduce mould risk.

• Preferred conditions: temperate or hot and dry
• Height: up to 120 cm
• Estimated yield: up to 100 g per plant

Harvest

Plan seasonal outdoor harvests for March–May, while remembering that an autoflower planted in spring may mature sooner. Rather than relying only on the calendar, observe flower maturity, aroma, resin development and overall plant condition. Actual timing, colour, yield and potency vary with climate, phenotype and cultivation decisions.
