About Old School OG Feminised

South Africa is really two growing countries, and Old School OG 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 20% 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: easy. In flower for 55-65 days. Stands 90-120 cm. Medium. Indoors it returns up to 300 g/m2. Outdoors, up to 450 g/plant a plant.

Stabilisation Notes β€” What This Means for Your Grow

BX3 is the credible stabilisation point for a clone-only recent-era cultivar. We worked Old School OG through three backcross generations to recreate the elite cut in seed form. A sibling male pollinates the mother each cycle to drive trait fixation.

Breeding Goal

Translate a clone-only recent-era cultivar to seed without losing the mother profile.

Selection Focus

Chosen for trichome coverage, stout structure and consistent flowering time across the pack.

Pollen / Mother Source
