About Arctic Sun Feminized
The genetic expression of Arctic Sun — a 24/76 sativa — varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: an upright, vigorous plant with narrow leaf fingers and elongated flower clusters that develop gradually over a longer bloom period. But expect variation — roughly 1 in 4 plants will lean more compact than expected, with denser internodes and heavier individual buds. THC testing at 22% across phenotypes, with Limonene consistently dominant.
Genetic Expression in the Grow Room
The dominant phenotype — which appears in roughly 70-75% of seeds — produces a taller, more open plant with narrower leaf fingers and elongated bud structure. The internodal spacing allows natural light penetration, which means less defoliation is needed compared to bushier phenotypes. Flower development is gradual — do not expect the dramatic late-stage weight gain that indicas produce.
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, 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 22% THC, Arctic Sun delivers energetic, calm effects with a limonene-influenced character. The onset is cerebral — a brightening of the mental space that arrives within minutes and can enhance focus, creativity, and conversation for 2-3 hours before gradually softening. The body stays comfortable without heaviness. The limonene dominance keeps the mental space bright and slightly elevated even when the body relaxes.
Terpene Profile
Dominant terpenes: Limonene (primary), Pinene (secondary), Terpinolene (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 pinene top notes that combustion destroys.
Who Should Grow Arctic Sun
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.
