White Widow Seeds

Genetics & effects

White Widow is a renowned indica-leaning hybrid, commonly reported as a cross between a Brazilian sativa landrace and a South Indian indica landrace. Its approximate 60% indica and 40% sativa balance supports sturdy growth, generous branching and dense flowers with a distinctive frosted appearance. This feminised selection is intended to produce female plants, making it a practical choice for growers who want to focus their space on flower production.

THC levels are commonly listed at 15–25%, while CBD is typically around 0.1–0.2%. Individual experiences vary, but users often describe the effects as initially euphoric, uplifting and creative, followed by a happy, physically relaxed feeling. The aromatic profile combines earthy, herbal and woody notes with spicy incense and a light sweetness. Myrcene, beta-caryophyllene and pinene are among the commonly associated terpenes.

Growing in New Zealand

White Widow suits intermediate growers and can adapt to indoor rooms, greenhouses or sheltered outdoor positions. It generally favours warm, dry or temperate conditions. In New Zealand, outdoor planting is usually planned for spring, from September to November, once cold snaps have passed and daylight hours are increasing. Local conditions differ considerably, so account for wind, rainfall, humidity and overnight temperatures when choosing a site.

Its dense flowers require regular airflow and moisture monitoring, particularly in humid districts. Give plants enough space for air to move through the canopy, avoid leaving foliage wet late in the day and inspect flower clusters regularly to reduce the risk of mould.

Indoor

Indoors, White Widow can reach up to 110 cm and usually finishes flowering in approximately eight to nine weeks. A well-managed canopy helps light reach multiple flowering sites. Low-stress training, selective pruning and an even branch structure can keep vertical growth manageable without placing unnecessary pressure on the plant.

Reported indoor yields reach up to 550 g/m² under favourable conditions. These figures are reference points rather than assured outcomes, as lighting, environment, plant health and grower experience all influence performance. Maintain steady air movement and keep humidity appropriate as flowers gain weight.

Outdoor

Outdoor plants may reach up to 140 cm and can produce up to 700 g per plant in favourable settings. Choose a sunny, sheltered position with free-draining soil and good airflow. Support may be useful as branches fill out. In wetter regions, a covered but ventilated area can help limit prolonged exposure to autumn rain.

Harvest

New Zealand outdoor harvest generally falls between March and May. Check flower maturity rather than relying only on a calendar date, as latitude, planting time and seasonal weather can shift the finish. The plant’s colour, aroma and flower density typically become more pronounced late in bloom. Handle mature flowers carefully and use a clean, well-ventilated drying space to preserve their earthy, sweet and spicy character.
