Fire OG is a hybrid from The Cali Connection, the California seed company behind a long run of OG Kush lines. It crosses Raskal's OG Kush with SFV OG Kush and has only ever been sold as regular seed.
The name comes from the look of the flower. Leafly describes frosty red hairs that make the buds appear to be on fire. Users there have left 1,260 ratings, averaging 4.4 stars.
Two Cali Connection OGs as parents
Both parents come from The Cali Connection. Leafly lists Raskal OG, also called Raskal OG Kush, as a cross of OG Kush and SFV OG Kush. Its buds are dense, light and dark green, sticky yet soft when broken apart.
SFV OG takes its name from California's San Fernando Valley and descends from OG Kush. Leafly notes four phenotypes, three leaning sativa and one more indica. The plant prefers a dry outdoor climate and thrives when grown large. Motorbreath and Larry OG are among its offspring.
Because SFV OG sits inside Raskal's OG as well, Fire OG carries that Valley cut on both sides. Leafly shortens the family to OG Kush × SFV OG Kush and files the result as an indica-dominant hybrid.
Regular seeds and a late swell
Seedfinder lists Fire OG as a 50/50 hybrid that flowers in 9–10 weeks, around 70 days. It grows indoors, outdoors or in a greenhouse, and yields run moderate to heavy. THC falls in the 20–24.99% band.
The breeder pitches Fire OG to intermediate and expert growers and calls for running it full term. Bud swell and resin production double at the end of week 10. Flipped at 12–14 inches, plants finish around 3.5–4 feet tall.
Weedmaps adds that the sticky, resin-heavy buds need careful humidity control. The plant stays compact with the dense structure typical of OG genetics and does well in warm, dry, Mediterranean-style climates.
Other breeders, other Fire OGs
The Cali Connection version is the reference point, but the name has traveled. Weedmaps notes that Humboldt Seed Company crossed the same lineage with its Humboldt OG for a heavier indica lean. Purple Caper Seeds went another way, pairing a 5K OG Kush cut with Fire Lady.
Seedfinder counts about four Fire OG entries across breeders. It also lists crosses built on Fire OG, including Emerald Fire OG from Humboldt Seed Company and Angel Cake from RedEyed Genetics.
The Cali Connection itself works as an umbrella for breeders from Southern and Northern California. Seedfinder credits it with 88 strains, including Tahoe OG Kush, SFV OG Kush, Raskal's OG Kush and Alien OG.
A parent to Animal Cookies and WiFi
Fire OG's reach shows in its offspring. Leafly lists Animal Cookies as a cross of GSC and Fire OG, with dense, frosty green buds tipped in purple and a 9–10 week flower. Animal Cookies went on to parent Apple Fritter and Animal Mints.
The other branch is White Fire OG, a cross of Fire OG and The White. It also goes by WiFi OG, WiFi, White Fire and WiFi Kush. Leafly averages it at 22% THC and lists White Durban and Wifi 43 as its children.
Fire OG users on Leafly most often report feeling relaxed, tingly and euphoric. Leafly calls the effects potent and long-lasting, with lemon, earth and pine on the palate.
