About XXX 420 Feminised
Will XXX 420 handle a South African summer outdoors? Yes. Put this 65/35 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 45-50 days, placing harvest between March and May across most provinces.
What yield is realistic? 350–450 g/m² indoors is reachable under decent LED with steady feeding. Outdoors, 450–650 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% 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 Bisabolol underneath.
Difficulty: moderate. In flower for 45-50 days. Stands Medium (150-245 cm). Indoors it returns 350–450 g/m². Outdoors, 450–650 g/plant a plant.
