About Kush XL Auto
Will Kush XL handle a South African summer outdoors? Yes. Put this 68/32 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 8-10 weeks seed to harvest, placing harvest between March and May across most provinces.
What yield is realistic? 300-400 g/m2 indoors is reachable under decent LED with steady feeding. Outdoors, 700 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 17% 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 8-10 weeks seed to harvest. Stands 60 cm. Indoors it returns 300-400 g/m2. Outdoors, 700 g/plant a plant.

Kush XL Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
Kush XL is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the purple expression the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Lock the autoflower trait in Kush XL through five generations of selection.
Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.
Royal King Genetics breeding facility — pollen from internally selected sibling males of the recurrent parent.
