Jack Herer Seeds

Kiwi Seed Bank presents Jack Herer as a feminised seed selection for the New Zealand catalogue. This renowned hybrid balances vigorous growth, generous production potential and a layered aromatic profile. It is best suited to growers with some experience managing stretch, airflow and flowering nutrition.

Genetics & effects

Jack Herer combines Haze × Northern Lights #5 × Shiva Skunk, with an estimated 55% sativa and 45% indica profile. THC is listed at 15–24%, while CBD is listed at 0–1%. Individual plants and finished flowers can vary according to phenotype and growing conditions.

The aroma and flavour may bring together bright citrus, dry pine, warming spice and a recognisable haze note. Terpinolene, caryophyllene and pinene are among the associated terpenes. Subjective experiences are often described as energetic, euphoric, focused, happy or social, sometimes followed by a more relaxed feeling. Personal experiences can differ.

Growing in New Zealand

This feminised variety is rated intermediate and may suit temperate as well as hot, dry conditions. New Zealand’s regional differences matter: the upper North Island generally offers a longer, warmer outdoor window, while cooler southern areas may require a sheltered position and closer attention to late-season weather.

For outdoor cultivation, spring planting usually falls between September and November. Choose a sunny location with free-draining soil and reliable airflow. As flowers gain weight, checking dense growth after rain can help reduce the risk of mould. Always consider applicable local rules before germination or cultivation.

Indoor

Indoors, Jack Herer can reach up to 130 cm. Its Haze influence may produce noticeable vertical stretch, so early canopy planning can help make good use of available space. Gentle training and an even canopy may improve light distribution without placing unnecessary stress on branches.

The flowering period is approximately 9–10 weeks. Under suitable conditions, listed indoor production is up to 600 g/m². These figures are reference points rather than assured outcomes, as lighting, environment, plant health and grower experience all influence performance.

Outdoor

Outdoor plants can grow to up to 180 cm where root space, sunlight and weather are favourable. A warm, open position is preferable, with enough room for branching and air movement. Supports may be useful as flowers become heavier. In humid districts, avoid overcrowding and inspect plants regularly during wet autumn periods.

Potential outdoor production is listed at up to 700 g per plant. Actual results can vary substantially with planting time, climate, soil quality, seasonal conditions and cultivation method.

Harvest

In New Zealand, outdoor harvest commonly falls between March and May. Exact timing depends on latitude, phenotype, planting date and seasonal weather. Watch flower development rather than relying only on the calendar, and plan ahead for autumn rain. At harvest, this favourite can display resinous flowers with haze, citrus, pine and spice notes, though colour, density and aroma will vary between plants.
