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 2026-04-01 on 300 seeds.
About Kahuna Auto
Kahuna is a 14/86 sativa testing at 20% THC with a terpinolene-dominant terpene profile. At a practical level, this means a plant that stretches 40-60% after the flip and produces elongated colas with good light penetration through the canopy, finishing in 8-10 weeks. The Terpinolene/Limonene 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: 350-450g/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. Terpinolene 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
Kahuna at 20% THC produces euphoric, creative, calm sensations that users consistently describe as mentally engaging with a creative or social quality that makes it a daytime-appropriate choice for many users. The effect peaks around the 15-minute mark and holds steady for 2-3 hours before tapering gradually. The Terpinolene/Limonene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other sativas at similar THC levels.
Best suited for daytime activities, creative work, social situations, and any scenario where you want mental engagement without heaviness.
Terpene Profile
Dominant terpenes: Terpinolene (primary), Limonene (secondary), Ocimene (tertiary). This combination produces a flavor that rewards patience in the cure — the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow Kahuna
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.

Kahuna 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.
Kahuna is our F5 autoflower line. Five generations of selection have fixed both the autoflower trigger and the haze-character terps the cultivar is known for. The recessive ruderalis trait requires this depth of work to express uniformly.
Stabilize the recessive ruderalis trait in Kahuna for uniform auto-trigger.
Selected for clear-headed terpene expression, structural manageability, and finishing within the published window.
