About Black Widow Feminised

Will Black Widow handle a South African summer outdoors? Yes. Put this 86/14 indica in the ground between September and November and you will be cutting from March to May. It stays low enough not to clear a boundary wall, and the short frame carries more weight than its size suggests. Bloom runs 9-10 weeks, placing harvest between March and May across most provinces.

What yield is realistic? 350 - 450 g/mΒ² indoors is reachable under decent LED with steady feeding. Outdoors, up to 400 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 27% THC with linalool in front, the return on effort is good.

How much can go wrong before it shows? Some. Anyone who understands pH, a feeding schedule and a light cycle will be fine. Neglect it entirely and it will suffer, but a single missed watering will not undo the grow.

The Aromatic Three

Leading with Linalool, then Myrcene, and Caryophyllene underneath.

Difficulty: medium. In flower for 9-10 weeks. Stands Up to 160 cm. Indoors it returns 350 - 450 g/mΒ². Outdoors, up to 400 g/plant a plant.
