About Ace Killer OG Auto
Will Ace Killer OG handle a South African summer outdoors? Yes. Put this 66/34 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 350 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, up to 400 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 25% 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: intermediate. In flower for 55-65 days. Stands Short. Indoors it returns up to 350 g/m2. Outdoors, up to 400 g/plant a plant.

Ace Killer OG is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive — fixing it takes multi-generation work — and at F5 the auto trigger and finish window are welded across the pack.
Stabilise the recessive ruderalis trait in Ace Killer OG for uniform auto-trigger.
Chosen for indica vigour, compact bud formation and a reliable finish window.
