About Jelly Roll Auto
Will Jelly Roll handle a South African summer outdoors? Yes. Put this 72/28 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 200 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 250 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 16% 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: easy. In flower for 55-65 days. Stands 90-120 cm. Medium. Indoors it returns up to 200 g/m2. Outdoors, up to 250 g/plant a plant.
