About Alpine Blue Feminised
Will Alpine Blue handle a South African summer outdoors? Yes. Put this 49/51 hybrid in the ground between September and November and you will be cutting from March to May. The balanced genetics take what the country gives them, from coastal humidity in KwaZulu-Natal through to dry Karoo heat. 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 350 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 17% THC with caryophyllene 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 Caryophyllene, then Myrcene, and Humulene underneath.
Difficulty: easy. In flower for 55-65 days. Stands Medium (150-245 cm). Indoors it returns up to 350 g/m2. Outdoors, up to 350 g/plant a plant.
