About King Kong Feminized

The genetic expression of King Kong — a 80/20 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 Myrcene 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 9-11 weeks across phenotypes. Yield: 400-500g/m² indoor, 350-500g/plant outdoor. Height: Compact (2-3 ft). Rated intermediate — the phenotype variation adds a layer of interest without adding significant difficulty. Growing from feminized seeds.

Effects and Use

At 20% THC, King Kong delivers happy, relaxed, sleepy effects with a myrcene-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 myrcene dominance adds depth and sedative potential, especially at higher doses.

Terpene Profile

Dominant terpenes: Myrcene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.

Who Should Grow King Kong

Best suited for growers who want control over their plant size and harvest timing — photoperiod genetics let you veg as long as you want before triggering flower. 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.
