Yeti OG: The Loompa Farms Leviathan
Yeti OG: The Loompa Farms Leviathan
Strain Overview
Type: Indica-Dominant Hybrid (70% Indica / 30% Sativa)
Breeder: Loompa Farms
Lineage: Loompa’s Headband (Underdog OG cut) Backcross (BX)
Market Status: The "Cult-Classic Heavyweight"; Yeti OG is a legendary piece of Northern California breeding history. Originally released by the highly respected underground breeders at Loompa Farms under the name Headband BX, the strain was later rebranded to "Yeti OG" to stand out in a market flooded with generic Headband knock-offs. It is famous for taking the elite, face-melting potency and sour-gas flavor of Loompa's famous Headband cut and beefing it up into a towering, massive-yielding monster that produces some of the greasiest, most resin-soaked OG buds in existence.
THC Content: Very High (22% – 26%+)
Dominant Terpenes: Caryophyllene, Myrcene, Limonene, Humulene
Key Effects: Intense "Headband" Pressure, Narcotic Body Stone, Euphoric Haze, Severe Munchies
Yeti OG lives up to its mythical namesake.
It is a massive, hairy beast of a plant. It abandons the finicky, low-yielding nature of typical OG Kush cuts, rewarding growers with huge, chunky colas that reek of sour lemon, diesel exhaust, and damp pine forest. It is a connoisseur-grade powerhouse that delivers a high starting with an intense, vice-like grip around the temples, eventually pulling you down into a deep, inescapable couch-lock.
History and Lineage: Rebranding a Legend
To understand Yeti OG, you have to understand the legacy of Loompa Farms.
The Mother (Loompa’s Headband / Underdog OG): In the elite circles of NorCal, Loompa’s cut of Headband (often referred to as Underdog OG to distinguish it from Sour Kush crosses) is considered one of the holy grails of the "Gas" era. It is devastatingly potent, with a distinct sour-lemon-hash profile. However, like many elite OG clones, it could be a low yielder and finicky to grow.
The Project (Headband BX): Loompa set out to lock the traits of this elite clone into seed form. They took the Underdog cut and backcrossed it (BX) to a select male from the same genetic line, aiming to increase vigor, yield, and stem strength without diluting the legendary potency.
The Synthesis (Yeti OG): The resulting seeds were so massive, hairy, and frost-covered that the name "Headband BX" simply didn't do them justice. The strain was dubbed Yeti OG. It captured the exact sour-gas flavor and the famous "headband" effect of the mother, but grew with terrifying, monstrous vigor.
Terpene Profile: Sour Gas and Forest Floor
The aroma of Yeti OG is incredibly "dank." It smells like an old-growth forest that just had a fuel spill.
Dominant Terpenes
Caryophyllene (The Fuel): The dominant terpene. It provides the aggressive diesel fumes, black pepper, and sharp spice that make your eyes water when you open the jar.
Myrcene (The Earth): Highly present. It grounds the sharp gas with a heavy, musky, damp potting soil base. It gives the strain its "Boreal Forest" vibe and drives the heavy sedation.
Limonene (The Sour): Adds a biting, astringent sour lemon cleaner note that slices right through the heavy musk.
Humulene (The Hash): A background note that adds a dry, woody, cedar-like finish, often translating to a rich "hashy" flavor on the exhale.
Flavor Notes:
The Aroma: It is loud and lingering. It smells of sour lemon, spilled gasoline, wet pine needles, and spicy hash.
The Smoke: Incredibly thick and greasy. It tastes of sour citrus and diesel fuel on the inhale, with a heavy, earthy pine finish on the exhale that coats the mouth.
Strain Effects: The Avalanche
Yeti OG is not for beginners. It possesses the intense cerebral start of a Chemdawg/Headband descendant, followed by the crushing weight of a pure Indica.
The Experience
The Grip: The high hits instantly with the trademark "Headband" effect—a literal feeling of tight, rushing pressure around the crown of the head and right behind the eyes. It is intensely euphoric and slightly disorienting.
The Haze: For the first 30 minutes, your brain is in a foggy, blissful haze. You might find yourself staring blankly at the TV or losing your train of thought mid-sentence.
The Avalanche: As the cerebral rush settles, a massive wave of physical gravity drops into your shoulders and back. Your limbs feel numb, heavy, and completely relaxed.
The Hibernation: The appetite stimulation is ferocious. After you empty the fridge, the narcotic traits take over, pulling you into a deep, restorative sleep.
Best For: Severe insomnia, chronic pain, migraines (due to the pressure-relieving headband effect), appetite loss, and high-tolerance OG veterans.
Growing Yeti OG: The Hairy Monster
This strain is beloved by commercial and craft growers alike because it fixes the biggest problem with OG genetics: the yield.
Growth Structure
The Size: Massive. Yeti OG is a stretcher. It has explosive vegetative vigor and will easily double or triple in height during the first three weeks of flower.
The Yield: Extra-High. Unlike the wispy golf balls of standard OGs, Yeti produces thick, chunky, grenade-sized colas that stack heavily down the branches.
The Support: Absolutely Mandatory. Despite thicker stems than the mother cut, the buds get so heavy and greasy that they will snap the branches if not heavily supported with a SCROG net or stakes.
The Resin: Greasy. The trichomes on Yeti OG are notoriously oily and greasy, making it an absolute dream for hash makers and rosin pressers.
The Time: It requires a bit of patience, usually finishing in 9 to 10 weeks (63–70 days) of flowering.
Grower’s Tip: Yeti OG loves a heavy feed, particularly Calcium and Magnesium, during the stretch phase. Because the colas are so large and dense, you must ensure pristine airflow. It can be susceptible to powdery mildew or bud rot if humidity spikes in the final weeks of flower. Defoliate heavily beneath the canopy.
Similar Strains / Lineage Relations
If you enjoy the profile or growth of Yeti OG, you might also appreciate these three genetically related or similar strains:
Samsquatch OG (Mephisto Genetics): The Autoflower Offspring.
Why: As detailed in the previous review, this is Mephisto's auto version created using the Yeti OG clone. It offers the same massive yield and earthy/sour profile in a fast, 80-day autoflower format.
Loompa's Headband (Underdog OG): The Mother Cut.
Why: If you want to experience the purest, original sour-gas potency that started it all, and don't mind a slightly smaller yield, tracking down the legendary mother clone is a must for genetic collectors.
Motorbreath (#15 Cut): The Modern Heavyweight.
Why: A cross of Chemdog D x SFV OG. If you want a similar towering, high-yielding OG that leans even heavier into the industrial chemical/fuel gas profile, Motorbreath offers a very similar face-melting experience.
Final Verdict: The Loompa Farms Leviathan
Yeti OG is a masterclass in thoughtful breeding. Loompa Farms managed to take one of the most elite, closely guarded clones in Northern California and stabilize it into a format that yields heavily, grows vigorously, and retains every drop of that boutique sour-gas flavor. It is a strain that commands respect, offering a cerebral rush that transitions into a devastating body stone. If you want to grow an OG that actually fills the jars, the Yeti is the beast you want in your tent.
You should choose Yeti OG if:
You love Sour Lemon/Gas/Earth flavors.
You want Massive OG Yields.
You enjoy the "Headband" Cerebral Pressure.
You make Hash or Rosin.
