Gorilla Glue #4 (fast) feminized seeds deliver the full resin output and high-THC character of the original GG4, compressed into a flowering window of just 45 to 50 days. This fast-flowering phenotype was selectively bred to preserve the source strain's potency — 18 to 25% THC — while cutting weeks off the standard harvest timeline. The result is a hybrid that performs reliably under both controlled indoor conditions and variable outdoor environments.
Genetics & Lineage
Gorilla Glue #4 originates from a three-way cross of Chem's Sister, Sour Dubb, and Chocolate Diesel, a combination that produced one of the most resin-dense phenotypes of its generation. The fast-flowering version from PPS introduces early-finishing genetics to that foundation — typically achieved by crossing the original with a fast or autoflowering line — while maintaining fully photoperiod-dependent behaviour. The hybrid ratio sits at roughly 60% indica, 40% sativa, giving it a growth structure and effect profile that bridges both categories without sitting firmly in either.
Aroma, Flavour & Effects
The terpene profile is led by caryophyllene and myrcene. Caryophyllene delivers the strain's sharp, spicy-diesel edge and is notable for binding to CB2 receptors, making it one of the few terpenes with direct cannabinoid-adjacent activity — associated with anti-inflammatory and stress-relieving properties. Myrcene adds the earthy, resinous base beneath the fuel top note. In the final two weeks before harvest, aroma intensity increases significantly; adequate ventilation in the grow space is not optional at this stage.
On the palate, expect a thick diesel exhale layered with resinous pine and a faint chocolate-earth finish — a flavour profile that reflects the Chocolate Diesel parentage clearly. Effects onset is relatively fast and begins cerebrally before settling into the body. The sativa component keeps early effects clear and functional; the indica influence builds over 30 to 60 minutes into a heavy, relaxed state. With THC in the 18 to 25% range, dosing is worth approaching deliberately, particularly for less experienced consumers.
Growing Profile
Flowering completes in 45 to 50 days indoors under a 12/12 light cycle, making this one of the faster-finishing photoperiod feminized strains available. Indoor yields average 500 to 600g per square metre under optimised conditions — adequate lighting, canopy management, and a stable environment between 20 and 26°C. Outdoors, plants are typically harvest-ready by late September in the northern hemisphere, with per-plant yields reaching 600g or more in a full-season grow with sufficient root space.
Plants grow to a moderate height — generally 90 to 130cm indoors — and respond well to LST (low-stress training) and SCROG setups that open the canopy and improve light penetration across the lower bud sites. The shortened flowering window makes this variety particularly well-suited to greenhouse cultivation, where it can exit before autumn humidity becomes a problem. Resin production is heavy; growers harvesting by hand should expect significant trichome accumulation on scissors and gloves.
Who This Strain Is For
The fast flowering time makes this strain a practical choice for growers operating in climates with shorter outdoor seasons, or for those running multiple indoor cycles per year who cannot afford a 65-day flowering period. Experienced cultivators will appreciate the resin yield and terpene complexity; beginners will find the feminized genetics straightforward to manage with basic training techniques. It suits consumers looking for pronounced physical relaxation without full sedation, and those who value a complex flavour profile over one-dimensional sweetness.
A proven genetic foundation, a meaningfully shorter flowering period, and consistent resin production make this a dependable addition to any serious cultivation rotation.
