King Louis OG
Also known as: King Louis XIII, Louis XIII Kush, King Louie
Breeder: Unknown (SoCal clone-only)
King Louis OG is a legendary indica-dominant hybrid that has reigned as one of Southern California's most revered cultivars since the early 2000s. Named after the French monarch, this strain rules the indica world with deeply sedating effects, extraordinary resin production, and a pungent gas-and-pine aroma that announces its presence from across the room. King Louis OG emerged from the Southern California cannabis scene during the 2000s as a clone-only selection within the OG Kush family. While the original breeder remains unknown, the most widely accepted lineage is OG Kush crossed with LA Confidential (itself an Afghani-rooted indica popularized by DNA Genetics). Some sources describe the cut as a distinct OG Kush phenotype rather than a deliberate cross, which accounts for the near-identical terpene fingerprint it shares with its OG parent—dominated by myrcene, caryophyllene, and pinene with secondary limonene. The "XIII" moniker references King Louis XIII of France and lends the strain its regal branding, though the connection is purely nominal. Zamnesia later stabilized the variety into feminized seed form using the OG Kush × LA Confidential cross, giving home growers access to the genetics without hunting the historically clone-only lines. THC content typically ranges 20–28%, with minimal CBD (<0.1%), and the effect profile is heavily sedating—full-body relaxation, pain relief, and sleep induction. The terpene blend produces a loud pine-diesel-earth aroma that fills a room and is immediately recognizable to anyone familiar with OG genetics. King Louis remains a benchmark for classic West Coast "gas and pine" cannabis, demonstrating enduring demand for traditional OG profiles even as newer exotic hybrids dominate dispensary menus.
Lineage & Genetics
Cross: Undisclosed x Undisclosed
OG Kush originated in Florida in the early 1990s (Chemdawg x Lemon Thai x Hindu Kush), contributing fuel-kush backbone and heady euphoria. LA Confidential from DNA Genetics (OG LA Affie x Afghani) contributes dense indica structure and deep sedation.
Lineage Dispute
Most dispensary resources describe this as OG Kush x LA Confidential, but the exact lineage is unconfirmed. Seedfinder.eu lists it as an OG Kush clone-only selection. Provided to Prime Cuts by one of their clients.
Terpene Profile
Myrcene — 0.7–1.2% — earthy, musky, herbal; drives the heavy sedating body effects
Caryophyllene — 0.5–0.9% — spicy, peppery, woody with anti-inflammatory properties
Pinene — 0.3–0.7% — sharp pine providing the signature forest-floor freshness
Aroma: Overwhelmingly pungent — dense pine forest over earthy musk and fuel. Sharp coniferous resin backed by heavy musky-earth base with classic OG gas notes.
Flavor: Sharp blend of spicy pine and sour citrus on the inhale with a woody forest-like finish. Exhale reveals deeper fuel/diesel notes with earthy-herbal quality.
Effects & Experience
Onset: Immediate and powerful within 1–3 minutes — warm cerebral wave quickly cascading into full-body immersion.
Opens with euphoric head rush, then within 5–10 minutes a heavy wave of physical relaxation descends. Full-body sedation follows with deep couch-lock and strong appetite stimulation.
Duration: 2–4 hours; residual sedation persists 4–6 hours
Commonly Reported Uses
Grower's Notes
King Louis OG is a classic SoCal clone-only indica that grows with textbook OG Kush morphology: compact, bushy architecture with tight internodal spacing and dense lateral branching. Expect moderate vegetative vigor rather than explosive growth. The stretch during the flip is restrained—typically 1.5× at most—making it well-suited for indoor rooms with limited vertical space. Topping early in veg is strongly recommended to break apical dominance and open the canopy, as the naturally tight structure traps humidity once flower sets begin stacking.
Yield
Structure and yield lean toward quality over quantity. Indoor gardens pull roughly 450–500 g/m² under optimized conditions, while outdoor plants in dry Mediterranean climates can reach 600 g per plant by mid-October. The plant develops a dominant central cola flanked by thick secondary branches; SCROG and SOG methods both work well with clones, and flipping early keeps a perpetual rotation efficient. Support stakes or trellis netting become necessary by week six of flower as the dense, rock-hard colas gain weight and can snap branches without reinforcement.
Flowering Time and Harvest
Flowering runs 56–63 days (8–9 weeks) for most phenotypes. Some growers push to 10 weeks chasing amber trichomes, but the consensus is that overextending flower degrades the pine-forward terpene profile this cut is known for. Harvest when trichome heads are predominantly milky with roughly 10–15% amber for peak potency and terp expression.
Nutrient Management
Feeding is moderate. King Louis responds well to a balanced nutrient program—heavy enough on CalMag and phosphorus through mid-flower, but taper nitrogen aggressively in the final two to three weeks to preserve terpene clarity and avoid harsh chlorophyll notes post-cure. In hydro, target EC 1.2–1.8 in veg and 1.6–2.2 in peak bloom; in soil or coco, err slightly lower. Excessive feeding dulls the terpene profile noticeably. The strain thrives in hydroponic setups, coco-perlite, and living soil alike. Supplemental CO2 (1,200–1,500 ppm) demonstrably increases bud density and final weight.
Environment and Climate
Environmental control is the make-or-break factor. Maintain daytime temps at 68–80°F (dropping 5–10°F at night in late flower can coax out subtle purple hues). Humidity targets: 60–65% RH in veg, 45–50% in early flower, dropping to 40% or below in the final two weeks. The dense bud structure is a magnet for Botrytis and powdery mildew if humidity creeps above 50% past week five—run oscillating fans through (not just above) the canopy, and defoliate strategically during weeks one and three of flower to maintain airflow to the interior. Lighting at 600–1,000 PPFD during flower drives resin production; the standard 18/6 veg and 12/12 flower cycle applies.
Wash and Extraction
Bud structure is dense, conical, and pine-cone shaped with tight calyx stacking. Flower color runs lime to deep olive green with fiery orange pistils and a thick, greasy blanket of milky-white trichomes. Cooler nighttime temperatures in weeks seven through nine can pull out dark purple undertones in the calyxes and sugar leaves. The resin coat is heavy enough to make the strain a candidate for solventless extraction; commercial washes from quality cuts using 73–149µ bags produce respectable returns, though King Louis is not considered an elite-yield washer on par with purpose-bred hash cultivars like GMO or Papaya. Expect roughly average OG-family wash returns—the value is in terpene quality (pine, gas, earth) rather than sheer volume.
Pest and Disease Resistance
The strain carries moderate natural pest resistance, but regular scouting for spider mites and thrips is essential, especially in indoor environments. Powdery mildew is the primary disease concern in addition to Botrytis in the colas—IPM programs with preventive sulfur or potassium bicarbonate applications during veg and early flower are recommended. Avoid any foliar sprays past week three of flower.
Drying should be slow
hang whole branches in a dark, climate-controlled room at 60–68°F and 55–62% RH for 10–14 days until stems snap cleanly. Cure in glass jars at 58–62% RH for a minimum of three to four weeks, burping twice daily for the first week, then once daily through week two, then every few days thereafter. The pine-fuel-earth terpene profile develops significantly during a proper cure—rushed drying produces a harsh, hay-like smoke that squanders the cultivar's signature bouquet.
History & Origin
Emerged from Southern California's OG Kush ecosystem in the early-to-mid 2000s, gaining recognition through Sun Valley Caregivers dispensary in Los Angeles. By the late 2000s it became a SoCal fixture and standard for heavy indicas.
