UFO-G, also sold as U.F.O.G, is an indica-dominant hybrid from Supernatural Seeds, released as feminized photoperiod seeds. It stacks three OG and Kush lines from three different breeders: Alien OG, Star Killer and Skywalker Kush.
The potency claims are steep. North Atlantic Seed Co., Breeders Collective and Her Seed Bank all list UFO-G at 30–32% THC, and the Supernatural Seeds UK storefront sells it to collectors chasing extreme potency and classic OG character.
Alien OG, Star Killer and Skywalker Kush
Alien OG comes from Cali Connection, crossing Tahoe OG with Alien Kush. Leafly calls it a heavy hitter, pairing strong body effects with a psychedelic cerebral buzz, and lists a 7–9 week flowering window.
Star Killer is a Rare Dankness creation, made by crossing Mazar × Blueberry OG with the breeder's own Rare Dankness line. It runs about 70% indica, flowers in roughly 65 days and builds dense, purple buds. Star Killer won Best Hybrid Flower at the 2016 Colorado Cannabis Cup.
Skywalker Kush comes from DNA Genetics, a cross of Skywalker and OG Kush. Leafly averages it at 23% THC and points to the heavy resin production that hash makers value. Its effects open with an uplift before easing into a calm body feel.
OG Kush runs through the family
With Tahoe OG behind Alien OG and OG Kush behind Skywalker Kush, UFO-G sits deep in the OG family. The same OG Kush backbone shows up in MK Ultra, the T.H. Seeds cross of OG Kush and G13 that took first place for indica at the 2003 High Times Cannabis Cup and second in 2004.
It also anchors Fire OG, which Leafly lists as OG Kush crossed with SFV OG Kush and files as an indica-dominant hybrid.
Seed sellers describe UFO-G's profile in OG terms. North Atlantic Seed Co. and Her Seed Bank list a bitter lemon and pine OG profile, backed by camphene, D-limonene and linalool. The UK storefront names limonene, myrcene, caryophyllene and pinene as the dominant terpenes.
Growing UFO-G from seed
Flowering estimates vary by seller. North Atlantic Seed Co. gives 65–75 days, Breeders Collective lists 9 weeks and the UK storefront quotes 8–9 weeks. That range sits close to the 65-day average Leafly gives for Star Killer.
The yield figures are generous. North Atlantic and Breeders Collective both list 500–550 grams per square meter indoors and 550–700 grams per plant outdoors. The UK storefront describes dense, resin-heavy flower, and its buyers report big harvests.
North Atlantic sells the seeds in pick-and-mix packs of 1, 3 or 5, and markets them as 100% organic. Her Seed Bank carries a 3-seed pack for $45, and Breeders Collective lists a pack at £29.99.
The Supernatural Seeds operation
The Supernatural Seeds UK storefront describes a female-owned seed brand run by female gardeners, registered under Tastebudz Collective LTD in Mildenhall, England. It sells feminized photoperiod and autoflowering seeds, sorted by flavor profile, as souvenir seeds.
The brand says it spent years refining pesticide-free organic cultivation. Seeds are hand picked, packed in recyclable packaging and kept in a humidity- and temperature-controlled room. Sellers describe the UFO-G high as powerful, euphoric and relaxed.
