About Silver Kush Auto
Will Silver Kush handle a South African summer outdoors? Yes. Put this 25/65 hybrid in the ground between September and November and you will be cutting from March to May. The balanced genetics take what the country gives them, from coastal humidity in KwaZulu-Natal through to dry Karoo heat. 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 200 g/plant a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 20% 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 Limonene, and Myrcene underneath.
Difficulty: easy. In flower for 50-60 days. Stands Medium. Indoors it returns up to 300 g/m2. Outdoors, up to 200 g/plant a plant.

Silver 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. Silver Kush sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.
Stabilise the recessive ruderalis trait in Silver Kush for uniform auto-trigger.
Chosen for vigour, terpene saturation and a tight finish window that allows production planning.
