Genetics & effects

Jack Widow brings together the lively haze character associated with Jack Herer and the dense, resinous structure linked with White Widow. The listed THC range is 15–21%, while CBD is listed at up to 0.5%. Aromas and flavours may combine bright lemon and fruit with incense, skunk, spice and classic haze notes.

Experiences are subjective and can vary. Some people describe Jack Widow as uplifting, social and talkative at first, followed by a more relaxed or sleepy finish. Individual impressions may differ according to setting, personal sensitivity and the finished flower.

Growing in Australia

Jack Widow is described as suitable for temperate regions and cooler areas with shorter summers. In Australia, outdoor planting generally aligns with spring, from September to November, once local conditions are reliably warm. Its intermediate difficulty reflects the need to manage height, airflow and a fairly vigorous canopy.

Choose a position with generous light and good air movement. Because regional weather varies considerably, growers should respond to their own climate rather than rely on a fixed calendar. In humid districts, sensible spacing and routine canopy checks can reduce the risk of mould around dense flowers.

Indoor

Indoors, plants may reach up to 120 cm, depending on container size, lighting, training and vegetative time. Early canopy shaping can help distribute growth and make better use of available space. Allow room for vertical stretch when flowering begins, and keep air moving through the lower and inner branches.

• Flowering time: approximately 9–10 weeks
• Indoor height: up to 120 cm
• Indoor yield: up to 650 g/m² in suitable conditions
• Experience level: intermediate

Outdoor

Outdoors, Jack Widow can become a large plant, reaching up to 300 cm where the season, root space and sunlight allow. Select a discreet, well-ventilated position with support available for long branches and weighty late-season flowers. Wind exposure, rainfall and cool autumn nights can influence final size and finish.

• Preferred climates: temperate and cool, short-season areas
• Outdoor height: up to 300 cm
• Outdoor yield: up to 1,000 g per plant in favourable conditions

Harvest

For outdoor plants in the southern hemisphere, harvest commonly falls between March and May. Timing should be based on plant maturity and local weather rather than date alone. Indoor plants are generally ready after the listed 9–10 week flowering window. Yield figures are maximum guide values, not assured outcomes, and vary with environment, plant care and growing experience.
