About Primus Feminised
Will Primus handle a South African summer outdoors? Yes. Put this 79/21 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 55-65 days, placing harvest between March and May across most provinces.
What yield is realistic? up to 350 g/m2 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 22% THC with myrcene 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 Myrcene, then Humulene, and Linalool underneath.
Difficulty: moderate. In flower for 55-65 days. Stands 90-120 cm. Medium. Indoors it returns up to 350 g/m2. Outdoors, up to 400 g/plant a plant.

Backcrossed twice to the dominant parental line. Primus now expresses resin density consistently across the population — what made the original cross interesting is preserved without the pheno-roulette of an unstabilised F1.
Stabilise the Primus cross into a seed-uniform line.
Chosen for indica vigour, compact bud formation and a reliable finish window.
