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 2026-02-15 on 500 seeds.
About Critical Kush Feminized
The genetic expression of Critical Kush — a 87/13 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 21% 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 9-11 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 feminized seeds.
Effects and Use
At 21% THC, Critical Kush delivers euphoric, calm 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 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 myrcene top notes that combustion destroys.
Who Should Grow Critical Kush
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.

Critical Kush Feminized — Sourcing & Genetics
Critical Kush Feminized was developed in the 1990s and has been continuously refined since — modern releases are far more stable than the original 90s phenotypes.
Cold-tolerant; performs well in short-season Northern states (ME, VT, MN, WI). Indoor cultivation works anywhere.
