About C4 Feminized

In a market saturated with hybrid genetics at the 20% THC range, C4 distinguishes itself through its limonene/caryophyllene terpene combination and its genuine versatility — this is not just a hybrid by label, it expresses balanced characteristics that make it adaptable to different use scenarios. Compared to similar genetics in our catalog, C4 trades raw potency for terpene complexity, which makes the flower more interesting to experienced users who have moved past judging quality by THC percentage alone.

How It Grows Compared to Similar Genetics

In the grow room, C4 sits in the practical middle ground that hybrid growers appreciate. Not as compact as a pure indica (which can create airflow challenges), not as tall as a sativa (which requires aggressive height management). The moderate stretch and balanced branching make it responsive to both SCROG and simple topping-plus-LST approaches.

Flowering: 9-11 weeks. Yield: 450-550g/m² indoor / 350-500g/plant outdoor. Height: Compact (2-3 ft). Difficulty: intermediate. Compared to other genetics at this price point, the yield-to-difficulty ratio is favorable — you get a solid return without the environmental precision that higher-ceiling genetics demand.

Effects and Use

At 20% THC, C4 delivers euphoric, focused, happy effects with a limonene-influenced character. The onset is balanced — head and body arrive together and remain proportional throughout a 2-3 hour duration. This makes the strain adaptable to different situations depending on dose. The limonene dominance keeps the mental space bright and slightly elevated even when the body relaxes.

Terpene Profile

Dominant terpenes: Limonene (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 C4

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.
