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. Louis XIII OG represents The Cali Connection's effort to make one of LA's most prized clone-only cuts available in seed form while improving upon the original's yield limitations. The Louis XIII clone — sometimes referred to as King Louis XIII — has been a staple in SoCal dispensaries since the early 2010s, prized for its pure OG expression with an unmistakable lemon-fuel-kerosene nose. By crossing it with Tahoe OG Kush S1 (itself a backcross of one of the most potent OG Kush expressions), The Cali Connection created a production-friendly version that maintains the lineage's intense effects and classic terpene profile. THC levels consistently reach 30%+ in optimized grows, with a 60% indica / 40% sativa phenotype that delivers profoundly relaxing, happy, and sedating effects. The dominant terpenes are caryophyllene and myrcene, contributing the earthy, spicy, lemon-fuel character that defines the OG Kush family.
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
Grower's Notes
Louis XIII OG by The Cali Connection is a pure California OG Kush expression that pairs the famous Louis XIII clone — a legendary LA/SFV/Sun Valley/Hollywood Hills cut renowned for its amazing structural genetics — with Tahoe OG Kush S1 to create a larger-yielding OG variant with enhanced bud production while maintaining the classic lemon-fuel-kerosene terpene profile that OG purists demand. The Cali Connection specifically designed this cross to address one of pure OG's common shortcomings: modest yields.
Growth Structure and Training
The plants develop a medium-to-tall structure with thick stems, larger leaf architecture, and robust lateral branching — all improvements over the typically lanky, lower-yielding pure OG phenotypes. This vigorous structure makes Louis XIII OG an excellent candidate for indoor training methods. SCROG is particularly effective, as the long, flexible branches are ideally suited for weaving through a screen to create a flat, uniform canopy. Topping, lollipopping, and trellising all produce strong results. The improved stem thickness compared to many OGs means the plants can support their heavy colas more independently, though support netting is still recommended for the densest phenotypes.
Flowering Time and Harvest
Flowering runs 65-70 days (approximately 8-10 weeks), a moderate timeline that allows the buds to fully develop their dense structure, prolific resin coating, and intense terpene expression. As flowering progresses, the colas bulk up significantly and often require support to prevent branch sag under the flower weight. The finished product is rich in aroma and covered in frosty trichomes — the combination of Louis XIII's structural genetics and Tahoe OG's resin production creates exceptional bag appeal and concentrate extraction potential.
Environment and Climate
Indoor growers should target temperatures of 68-80°F during the day with slightly cooler nights. The plants respond well to both HID and high-quality LED lighting, with light intensity being a key driver of resin production. Humidity management follows standard OG protocols: 50-55% in early flower, stepping down to 40-45% in the final three weeks to protect the dense colas. The OG lineage benefits from consistent airflow — position fans to keep air moving through the canopy, as the dense bud formation creates natural humidity pockets.
Nutrient Management
Nutrient demand is moderate to heavy. Start with balanced NPK in veg, transition to bloom formulations at the flip, and maintain steady feeding through mid-flower when bud weight accumulation peaks. The OG genetics can be sensitive to pH fluctuations — maintain 6.0-6.5 in soil and 5.5-6.0 in hydro/coco. Flush for the final 10-14 days to preserve terpene clarity. Indoor yields are reported as high by breeder standards, with optimized setups producing 500-550 g/m2. Outdoor plants perform best in warm, dry Mediterranean climates with ample sunlight, finishing in mid-October in the Northern Hemisphere with yields of 250-400 g per plant. The feminized version crosses Louis XIII to a Tahoe Kush S1 reverse male; regular seeds use SFV OG Kush IBL as the pollen donor, offering a slightly different expression for breeders interested in pheno-hunting.
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.
