What is Jet Fuel?
Jet Fuel (a.k.a. G6) is a Sativa-dominant hybrid bred by 303 Seeds, crossing Aspen OG with High Country Diesel. Testing at 17-22% THC, Jet Fuel earned its name from a sharp, gas-station-pump diesel aroma that hits the moment a jar opens. The strain has built a strong following in the Pacific Northwest and Colorado. Royal King Seeds carries feminized Jet Fuel across regional stores.
Reported effects
Jet Fuel lives up to its name with a fast-onset, high-energy cerebral burst that experienced consumers describe as "go-time." The high is motivating, focused, and clear — a daytime strain best suited to active tasks, exercise, or creative work. Effects taper after 2 hours into a mild relaxation rather than full body sedation. Caryophyllene + pinene profile delivers the diesel-pine character.
These are consumption effects reported by growers and consumers for this cultivar. Nothing here is medical advice or a claim that this plant treats, prevents or relieves any condition.
Growing Jet Fuel
Jet Fuel stretches 1.8-2.2x in flower — train aggressively with topping, FIM, or SCROG for canopy control. Flowering takes 9-10 weeks. Nutrients: EC 1.6-1.9 mid-flower. Indoor yields 400-500 g/m². Outdoor in dry Mediterranean climates yields 500-700 g per plant; harvest by mid-October. Diesel terpene profile is sensitive to drying conditions — slow-dry at 18°C, 60% RH for 10-14 days preserves the gas note.
