Royal King Genetics — first-party test batch
Numbers below are from our internal seed-lot QC and verified grower submissions, not breeder marketing. Determined from a single batch tested 2026-02-14 on 350 seeds.
About Blue Kush Auto
Blue Kush is a 55/45 hybrid testing at 20% THC with a caryophyllene-dominant terpene profile. At a practical level, this means a plant that offers moderate stretch with balanced branching that responds well to training, finishing in 8-10 weeks. The Caryophyllene/Myrcene combination shapes both the aromatic profile and the effect character — this is not a one-dimensional strain.
Growing Parameters
Flowering time: 8-10 weeks from flip. Indoor yield at 600+ PPFD: 300-400g/m². Outdoor in full sun with 5+ gallon containers: 500-700g/plant. Plant height indoors after training: Tall (4-5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Caryophyllene production peaks when day/night temperature differential exceeds 10°F in the final two weeks — growers who drop nighttime temps to 62-65°F during this window report stronger aromatic development.
This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.
What Users Report
Blue Kush at 20% THC produces relaxed, happy, euphoric sensations that users consistently describe as versatile enough to serve different purposes depending on dose and setting. Lower doses lean more cerebral and functional. Higher doses bring the body effect forward. The Caryophyllene/Myrcene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other hybrids at similar THC levels.
Best suited for flexible use across the day — lighter doses for daytime function, heavier doses for evening relaxation.
Terpene Profile
Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Humulene (tertiary). This combination produces a nose that develops complexity through the cure — expect the primary caryophyllene character to emerge first, with myrcene and humulene notes adding layers over 3-4 weeks in jars.
Who Should Grow Blue Kush
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.

Blue Kush Auto — Breeder Information
Royal King GeneticsBred and stabilized in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read our full 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 within a tight window.
Lock the autoflower trait in Blue Kush through five generations of selection.
Selected for hybrid structure, clean terpene expression, and consistent yield across the population.
