About Blue Widow Feminised

South Africa is really two growing countries, and Blue Widow does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 76/24 indica 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. Dense indica flowers at 16% THC are the wrong shape for a wet summer finish. Between Durban and Richards Bay, once humidity sits above 65% for days at a stretch, botrytis reaches the core of a cola before anything shows on the surface β€” defoliate early, space plants wider than feels necessary, and keep air moving under the canopy. That same density turns into an advantage on the Highveld: above 1 400 m the autumn nights go cold and dry, myrcene sharpens as the temperature drops, and a compact frame shrugs off a Free State storm that would flatten something taller.

The Aromatic Three

Leading with Myrcene, then Caryophyllene, and Linalool underneath.

Difficulty: medium. In flower for 50-55 days. Stands 100-120cm. Indoors it returns 525 g/m2. Outdoors, 1100 g/plant a plant.

Stabilisation Notes β€” What This Means for Your Grow

Blue Widow runs through our F3 programme. Most of the pack expresses the target dense flower architecture cleanly; the F3-to-F4 cycle is where we close out the last remaining off-types.

Breeding Goal

Stabilise Blue Widow across three rounds toward F4 production-ready stock.

Selection Focus

Chosen for resin output, a low-slung stature and a clean indica terpene fingerprint.

Pollen / Mother Source

Royal King Genetics in-house mother stock β€” pollen taken from a sibling male drawn from the same selected pheno population.
