White Widow Regular Seeds

Genetics & effects

White Widow Regular combines a Brazilian sativa landrace with a South Indian indica landrace. Its profile is approximately 60% indica and 40% sativa, bringing together compact growth and lively sativa character. This photoperiod variety is supplied as regular seed, so plants may be male or female. Growers planning a seedless flowering space will need to identify and separate males at the appropriate stage.

Reported THC levels range from 18–23%, while CBD is listed at 0.1–0.2%. Individual experiences vary, but adult consumers often describe the effects as powerful, euphoric, energetic and creative. The aroma and flavour lean herbal, sweet and woody, supported by a terpene profile featuring myrcene, caryophyllene and pinene.

Growing in the named country

In New Zealand, White Widow Regular is best suited to growers with intermediate experience. Its 7–8 week flowering period, moderate stature and preference for temperate or hot, dry conditions make it adaptable, but regular seeds require additional plant selection. Always check and follow current national and local rules before germinating or growing cannabis seeds.

For outdoor planning, spring planting falls between September and November. Choose timing according to local temperatures, daylight and frost risk rather than the calendar alone. Good airflow, sensible spacing and shelter from prolonged rain can reduce risk from mould, especially in humid or coastal areas.

Indoor

Indoors, plants may reach up to 110 cm. A consistent light cycle and early canopy management can help make efficient use of space. Monitor plants as they mature so male plants can be identified before pollen release if seedless flowers are the goal.

Keep air moving through and beneath the canopy, and avoid persistently damp growing media. Because environmental conditions and grower skill differ, the listed indoor yield of up to 700 g/m² should be viewed as a reference rather than an assured result.

Outdoor

Outdoors, White Widow Regular may grow up to 140 cm. A sunny, well-drained position is preferable, with protection from strong winds and late-season rainfall. Temperate regions can suit this variety, while cooler locations may benefit from a warm, sheltered microclimate. Inspect dense flowering growth regularly and maintain airflow to reduce risk from excess moisture and mould.

Under favourable conditions, outdoor production is listed at up to 700 g per plant. Actual growth, colour, aroma and output depend on phenotype, season, plant sex, soil, weather and cultivation choices.

Harvest

The flowering phase is approximately 7–8 weeks. For New Zealand outdoor gardens, harvest generally sits within the southern-hemisphere window of March to May, although regional conditions and planting time can shift maturity. Assess flower development directly rather than relying only on an estimated date. Its blend of manageable height, short flowering time and classic herbal-sweet character may make White Widow Regular a favourite for growers who value traditional genetics and the selection possibilities offered by regular seeds.
