About Grapefruit Kush Feminised
Will Grapefruit Kush handle a South African summer outdoors? Yes. Put this 70/30 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 days (indoor), placing harvest between March and May across most provinces.
What yield is realistic? Up to 600g per m2 indoors is reachable under decent LED with steady feeding. Outdoors, Up to 700g per plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 21% 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 Caryophyllene, and Linalool underneath.
Difficulty: easy. In flower for 55 days (indoor). Stands Medium. Indoors it returns Up to 600g per m2. Outdoors, Up to 700g per plant a plant.
