About White Widow Auto

South Africa is really two growing countries, and White Widow does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 50/40 hybrid does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. A 50/40 split travels better than either parent across a country running from subtropical coast to semi-desert. The canopy sits open enough to survive a humid KwaZulu-Natal autumn and dense enough to still look the part after a dry Karoo summer. At 26% THC with caryophyllene leading, what changes between a Johannesburg rooftop and a Cape smallholding is the schedule rather than the result.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Humulene underneath.

Difficulty: easy. In flower for 50-55 days (harvest 70-85 days after germination). Stands 30 - 90 cm. Indoors it returns 14 to 455 g/m2. Outdoors, 7 to 225 g/plant a plant.
