About Killer Grape Auto
Will Killer Grape handle a South African summer outdoors? Yes. Put this 86/14 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 50-60 days, placing harvest between March and May across most provinces.
What yield is realistic? up to 300 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 8% 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: easy. In flower for 50-60 days. Stands Short. Indoors it returns up to 300 g/m2. Outdoors, up to 350 g/plant a plant.
