About Blue Kush Auto
South Africa is really two growing countries, and Blue Kush does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 55/45 hybrid does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. A 55/45 split travels better than either parent across a country running from subtropical coast to semi-desert. The canopy sits open enough to survive a humid KwaZulu-Natal autumn and dense enough to still look the part after a dry Karoo summer. At 20% THC with caryophyllene leading, what changes between a Johannesburg rooftop and a Cape smallholding is the schedule rather than the result.
The Aromatic Three
Leading with Caryophyllene, then Myrcene, and Humulene underneath.
Difficulty: easy. In flower for 10-12 weeks. Stands Medium. Indoors it returns 350-400 g/m2. Outdoors, 150-200 g/plant a plant.

Blue Kush 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.
Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Blue Kush sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.
Lock the autoflower trait in Blue Kush through five generations of selection.
Chosen for hybrid frame, clean terpene expression and consistent yield across the population.
