About Royal Kush Auto

The genetic expression of Royal Kush, a 70/20 indica, varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a compact, bushy plant with broad fan leaves and golf-ball-dense flowers that pack on weight in the final two weeks. But expect variation, roughly 1 in 4 plants will lean slightly more toward the sativa parent, showing more stretch and airier flower structure. THC testing at 20% across phenotypes, with Caryophyllene consistently dominant.

Genetic Expression in the Grow Room

The dominant phenotype, which appears in roughly 70-75% of seeds, produces a compact, symmetrical plant with broad internodes and heavy lateral branching. Fan leaves are wide and dark green, typical of the indica heritage. Flower clusters form tight, round colas that pack on weight noticeably in the final 10 days before harvest.

The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 8-10 weeks across phenotypes. Yield: 450-550g/m² indoor, 400-600g/plant outdoor. Height: Short-Medium (2-3.5 ft). Rated intermediate, the phenotype variation adds a layer of interest without adding significant difficulty. Growing from regular seeds with autoflowering genetics.

Effects and Use

At 20% THC, Royal Kush delivers creative, energetic, relaxed effects with a caryophyllene-influenced character. The onset is body-first, a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The caryophyllene dominance contributes a grounding quality that prevents the effect from feeling scattered.

Terpene Profile

Dominant terpenes: Caryophyllene (primary), Myrcene (secondary), Bisabolol (tertiary). This combination produces a nose that develops complexity through the cure, expect the primary caryophyllene character to emerge first, with myrcene and bisabolol notes adding layers over 3-4 weeks in jars.

Who Should Grow Royal Kush

Best suited for growers who value speed and simplicity, autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results. Ships discreetly to all 50 US states with our germination guarantee.

Breeding Program
Autoflower Stabilization (F5), ruderalis trait fixing
Stabilization Notes, What This Means for Your Grow

Royal Kush is our F5 autoflower line. Five generations of selection have fixed both the autoflower trigger and the compact internode spacing the cultivar is known for. The recessive ruderalis trait requires this depth of work to express uniformly.

Breeding Goal

Stabilize the recessive ruderalis trait in Royal Kush for uniform auto-trigger.

Selection Focus

Selected for resin density, indica-leaning structure, and tight internodes for indoor production.

Pollen / Mother Source

Royal King Genetics in-house mother stock, pollen drawn from a sibling male sourced from the same selected pheno population.
