Black Widow Seeds

Genetics & effects

Black Widow is a feminised hybrid combining South American sativa with South Indian indica genetics. Its profile leans 40% sativa and 60% indica, pairing lively character with a heavier finish. Catalogue figures place THC at 18–28% and CBD at 0.1–1.5%, although actual expression can vary with phenotype and growing conditions.

Fruity notes meet pine, skunk and dry wood, supported by a terpene profile associated with myrcene, caryophyllene and pinene. Individual experiences differ, but Black Widow may feel happy and talkative at first, followed by a relaxing, sleepy mood. Some people also describe an increased appetite. Potency can feel substantial, so personal impressions may vary widely.

These feminised seeds may suit intermediate growers seeking vigorous hybrid growth, generous branching and dense flowers. Outback Seed Bank presents Black Widow as part of its Australian catalogue.

Growing in Australia

Black Widow is best matched with hot, dry or temperate conditions. In Australia, outdoor planting generally aligns with spring, from September to November, once local temperatures are stable. Climate differs considerably across the country, so timing should reflect regional frost, humidity and summer heat patterns.

Good airflow is important as flowers gain weight. Avoid crowding, keep the growing area clean and monitor moisture around dense growth to reduce the risk of mould. The plants can respond well to sensible canopy management and branch support, making some prior cultivation experience useful.

Indoor

Indoors, Black Widow may reach up to 160 cm. Training early can help manage vertical stretch and spread light across the canopy. Consider:

• Providing strong airflow above and below the canopy.
• Supporting branches before flowers become heavy.
• Maintaining consistent light, temperature and humidity.
• Allowing enough room between plants for inspection and access.

The flowering phase is listed at approximately 8–10 weeks. Under favourable conditions, indoor yields are listed at up to 700 g/m², but setup, phenotype and grower skill will influence the final result.

Outdoor

Outdoors, plants may reach up to 200 cm and can develop broad, productive branching. Choose a sunny position with well-draining soil and shelter from damaging winds. In humid districts, extra spacing and routine checks during late flowering can help reduce moisture issues. Listed outdoor yields reach up to 800 g per plant in favourable conditions, without assurance of a particular outcome.

Harvest

Australian outdoor harvest commonly falls between March and May. Exact timing depends on spring planting date, latitude, seasonal weather and plant maturity. Watch flower development rather than relying only on the calendar. Once collected, dry flowers slowly in a dark, ventilated space with stable conditions to preserve their colour, aroma and favourite fruity, pine and woody nuances.
