Green Crack (Fast) feminized seeds deliver the same energetic, sativa-leaning character as the original Green Crack, compressed into a photoperiod flowering window of just 8 to 9 weeks. This strain carries THC levels between 18% and 22%, and was specifically bred to reduce the time from flip to harvest without sacrificing the terpene profile or potency that made the original strain a grower staple. Feminized genetics ensure every plant develops as a flowering female, removing the guesswork from seed selection.

Genetics & Lineage

Green Crack (Fast) is derived from the original Green Crack, a strain widely attributed to Skunk No. 1 lineage that became prominent for its focused, stimulating effect profile. The fast-flowering version was developed by introducing genetics that accelerate the flowering cycle while preserving the core cannabinoid and terpene expression. The result is a hybrid that leans sativa in effect but behaves with the efficiency and compact structure more typical of indica-influenced phenotypes. The indica-dominant classification reflects its growth pattern and shortened flower development rather than its effect character, which remains clear-headed and active.

Aroma, Flavour & Effects

The primary terpenes in this strain are Linalool and Ocimene, which together produce a bold aromatic profile built around tropical fruit, ripe mango, and zesty citrus. A layer of subtle spice sits underneath and becomes more pronounced on the exhale, where the sweetness fades into a lingering warmth on the palate. The smoke is smooth with a clean fruity finish that makes it accessible even at higher THC concentrations.

Effects arrive quickly and lean toward the cerebral side. Users consistently report a surge in energy, sharpened focus, and increased motivation. Creative thinking is heightened without the scattered or anxious edge that high-THC sativa-leaning strains can sometimes produce. This makes Green Crack (Fast) well-suited to morning or early afternoon sessions, productive work, and social settings where engagement and conversation are the priority. The body remains relatively clear throughout, without significant sedation.

Growing Profile

Green Crack (Fast) performs well both indoors and outdoors. Indoor flowering completes in 8 to 9 weeks from the switch to 12/12 lighting, making it one of the faster photoperiod options available at this THC range. Indoor yields reach approximately 500 to 550 grams per square metre under optimised conditions, including consistent light intensity and managed canopy height. Outdoor plants finish by mid to late September in most northern hemisphere climates and can produce generous per-plant yields when given sufficient root space and direct sun exposure.

The plant structure is moderately compact with good internodal density, responding well to LST (low-stress training) and ScrOG setups that spread the canopy and improve light penetration to lower bud sites. Topping is straightforward on this strain and helps manage height in confined grow spaces. Difficulty level is suitable for growers with one or two previous grows under their belt, though the forgiving genetics mean first-time cultivators can achieve solid results with attentive feeding and environmental control.

Who This Strain Is For

Green Crack (Fast) suits growers who want a reliable, fast-finishing photoperiod strain with a functional daytime effect profile. It fits naturally into a Sea of Green or ScrOG setup and works for anyone running multiple harvests per year who cannot afford the longer timelines some photoperiod strains require. Consumers who rely on cannabis for focus, creative output, or sustained energy without sedation will find this strain consistently delivers those qualities across phenotypes.

For growers who value efficiency and consumers who value clarity, this is a strain that performs exactly as expected — every run.
