Louis XIII OG
Also known as: Louis XIII OG Kush, Louie XIII OG, King Louie XIII OG, King XIII OG
Breeder: The Cali Connection
Louis XIII OG is a seeded hybrid from The Cali Connection that crosses the legendary clone-only King Louis XIII cut — an elite LA/SFV OG Kush phenotype — with their Tahoe OG Kush S1. The result is a structurally improved, higher-yielding OG that retains the classic lemon-fuel-kerosene nose of the original clone while adding vigor, thicker stems, and heavier colas from the Tahoe OG side. Despite the breeder's sativa-leaning ratio, the effects are overwhelmingly physical: heavy sedation, euphoric onset, and deep body relaxation characteristic of elite OG lines. The strain produces prolific resin and dense, frosty buds that often require staking in late flower.
Lineage & Genetics
Cross: King Louis XIII x Tahoe OG Kush S1
King Louis XIII is a clone-only OG Kush phenotype from the LA/SFV/Sun Valley/Hollywood Hills area, considered one of the most potent and purely indica-dominant expressions of OG Kush. Renowned for extremely high THC (often 28%+), overwhelmingly narcotic sedation, and a pungent pine-earth-gas aroma. Tahoe OG Kush (The Cali Connection's version) is itself an OG Kush cross — Tahoe cut OG Kush x SFV OG Kush IBL — known for crushing physical sedation, sharp pine-lemon aromatics, and prolific resin production. The Tahoe parent contributes larger yields and sturdier branching to the cross.
Lineage Dispute
The Cali Connection labels this 60/40 sativa/indica, but both parents are indica-dominant OG Kush phenotypes, leading many growers and dispensaries to classify it as indica-dominant. Blimburn Seeds markets their version as 60/40 indica/sativa (reversed). Apothecary Genetics released a separate 'Louis XIII OG' using King Louis XIII x Joe's OG Kush — a different cross entirely. Frequently confused with the clone-only King Louis XIII (aka King Louis OG), which is a parent of this strain, not the same strain.
Terpene Profile
Myrcene — Earthy, herbal, musky foundation
Caryophyllene — Spicy, peppery warmth
Limonene — Bright citrus, lemon zest
Pinene — Fresh pine, forest-like brightness
Aroma: Intensely pungent lemon-fuel-kerosene nose that fills a room immediately. Sharp citrus top notes over deep earthy musk and classic OG gas. Breaking the buds releases a blast of Pine-Sol and Lemon Pledge with spicy diesel undertones. Cured flower retains the lemon-pine spike even months post-harvest when stored properly.
Flavor: Bright lemon-pine inhale with fresh citrus zest. Mid-palate transitions to earthy, woody fuel. Exhale finishes with smooth spicy diesel and a lingering sweet-sour kerosene aftertaste. Joints and blunts accentuate the pepper and wood; glass pieces highlight the zesty citrus aspects. In concentrates, the lemon-pine is amplified to near-overwhelming terpene intensity.
Effects & Experience
Onset: Fast and direct. An immediate euphoric head rush clears the mind within the first few minutes, accompanied by a wave of uplifting warmth behind the eyes.
The initial cerebral clarity quickly gives way to a heavy, full-body relaxation that deepens over 20–30 minutes. Deep couch-lock sets in as the sedation builds, often accompanied by strong appetite stimulation and a pleasant heaviness in the limbs. Despite the breeder's sativa label, the experience is overwhelmingly physical and indica-leaning. Muscles unwind completely and mental chatter quiets.
Duration: Long-lasting, typically 2–3 hours of strong effects. The sedation tail can persist 4+ hours, making this a poor choice for daytime productivity.
Commonly Reported Uses
Growing Characteristics
Grow Tips: The Cali Connection specifically notes thick stems and a larger leaf structure compared to the original clone. Colas become extremely heavy in late flower and REQUIRE staking or trellising to prevent branch breakage. SCROG and topping recommended to manage stretch and maximize light penetration. Reduce humidity to 40–50% RH during flower to protect dense buds from mold. Moderate feeder — excessive nutrients reduce terpene clarity. Well-suited for manifolding or mainlining early in veg. Harvest when trichomes are mostly cloudy with some amber for peak sedation. Resin production is prolific; well-formed trichome heads make this an excellent extraction cultivar. OG lines generally yield 3–8% ice water hash from fresh frozen material, with Louis XIII OG's heavy resin load suggesting above-average wash performance.
History & Origin
The Cali Connection created Louis XIII OG by crossing the elite clone-only King Louis XIII cut — a legendary OG Kush phenotype circulating in the LA/SFV/Sun Valley/Hollywood Hills scene — with their Tahoe OG Kush S1 male. The goal was to capture the original clone's exceptional terpene profile and potency in seed form while improving yield and structural vigor via the Tahoe OG parent. The Cali Connection's version won 1st Place Best Indica Flower at the 2015 High Times Medical Cannabis Cup in Colorado, and their 'Bhang Black Private Reserve (King Louis XIII)' — grown from these genetics by Bhang — took 2nd Place Best Indica at the 2016 LA Cannabis Cup. The strain remains a flagship offering in The Cali Connection's catalog. SeedFinder.eu tracks 37+ direct descendants of the original King Louis XIII clone across dozens of breeders, underscoring its importance as a genetic building block in the OG family tree.
