About Grapefruit Feminised

South Africa is really two growing countries, and Grapefruit does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 30/70 sativa 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. An open sativa canopy is the right structure for a humid coast, which is roughly how Durban Poison ended up the shape it is β€” air moves through the plant instead of sitting in it, and the botrytis pressure that ruins denser cultivars through a KwaZulu-Natal February mostly passes it by. The trade-off is the calendar. A 8-9 weeks bloom on the Highveld has to start early, which in practice means seedlings out by October, or the closing weeks run into frost. pinene expression is strongest where day-to-night swings exceed 10Β°C, and at altitude that is simply what autumn does.

The Aromatic Three

Leading with Pinene, then Limonene, and Caryophyllene underneath.

Difficulty: easy. In flower for 8-9 weeks. Stands 80-100 cm. Indoors it returns 500 g/m2. Outdoors, 300 g/plant a plant.

F3 stabilisation on the Grapefruit cross. Three rounds of selection have brought the population to roughly 80% trait homogeneity β€” a small fraction of pheno variance is still present and is being culled in the next cycle.

Breeding Goal

Reach trait homogeneity in Grapefruit through advanced filial refinement.

Selection Focus

Chosen for terpene saturation, sativa vigour and a workable finish time despite long-flowering genetics.
