About 501st OG Feminised
Will 501st OG handle a South African summer outdoors? Yes. Put this 74/26 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 7-9 weeks, placing harvest between March and May across most provinces.
What yield is realistic? 885 g/m² indoors is reachable under decent LED with steady feeding. Outdoors, Up to 400 gr a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 18% THC with linalool 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 Linalool, then Myrcene, and Caryophyllene underneath.
Difficulty: easy. In flower for 7-9 weeks. Stands Short. Indoors it returns 885 g/m². Outdoors, Up to 400 gr a plant.
