The King Louis strain is a classic cannabis strain known for its strong Kush aroma, high THC, and relaxing indica effects. King Louis, aka King Louis XIII, King Louie, King Louie XIII, Louis XIII Kush, and sometimes King Louis OG, is part of Southern California’s OG Kush strains. Most sources describe it as a cross between OG Kush and LA Confidential.
In practical terms, the King Louis strain is usually high in THC, low in CBD, and indica-leaning. It is often reported at around 20 to 25% THC, although some batches can test higher. Flowering time is around 7-9 weeks, depending on the exact version.

The King Louis strain belongs to the old-school West Coast Kush family. Its reputation comes from its dense flowers, pine-heavy aroma, high potency, and relaxing effect that is ideal at the end of the day. The name King Louis XIII is a direct reference to the French king himself, but let's be honest, this is just branding. There is no known historical connection between the strain and the king beyond its name.
Its exact origin is less clear than many would like to suggest. The most common stated origin of the King Louis XIII strain is a cross of OG Kush and LA Confidential. King Louis XIII may also have circulated first as a rare Los Angeles OG Kush cut.
Most public sources describe the King Louis XIII strain as OG Kush x LA Confidential. That means it combines two of the greatest West Coast classics: OG Kush for pine, fuel, citrus, and earthy Kush depth, and LA Confidential for its compact indica structure and stronger physical effects.
Other sources, however, describe King Louis XIII as a clone-only OG Kush phenotype instead of a cross. That is one reason why exact indica/sativa ratios can vary between genetic versions. In general, King Louis is an indica-dominant strain associated with strong body relaxation and sleepy evening effects.
The OG Kush strain is the most obvious genetic parent. The legendary Kush line is known for its mix of fuel, pine, lemon, skunk, earth and spice, which gives a mental uplift and physical calm. Sirius currently sells related OG Kush genetics such as BF OG Kush and RQS OG Kush.
LA Confidential is the other potential parent. It is usually described as a heavy indica strain with dense flowers, deep body calm, and an Afghani landrace strain profile. If your King Louis follows the OG Kush x LA Confidential lineage, LA Confidential may contribute to its compact structure, relaxing effects, and couch-lock character.
King Louis is generally described as a high-THC strain. Exact potency depends on the grower, phenotype, growing conditions, and even curing. King Louis flower is often reported at around 20% THC or higher, with some batches reaching into the upper 20% range. A batch around 20% THC can already feel strong for casual users, while flower above 25% THC is better for experienced users with a high tolerance to THC.
CBD content is usually low, so King Louis is not normally chosen for a balanced THC/CBD experience. Some people still report using King Louis weed for stress, sleep, appetite, or body relaxation, but that is not medical proof. If you are specifically interested in CBD-focused genetics, Sirius offers CBD medical seeds in the Seedshop. If you prefer concentrated CBD products that are easy to carry and take, visit Sirius online CBDshop for CBD oils, capsules, skin care, and more.
King Louis is not a sugary candy strain. It is a classic Kush-style strain with pine, wood, earth, musk, skunk, spice, citrus, and sometimes fuel-like taste. To enjoy cannabis aroma without burning the plant material, a weed vaporizer from the Sirius Vaporizershop is a good choice. Vaporizing avoids combustion and can help preserve more of the plant's flavor and aroma.
The taste of King Louis is usually piney, earthy, woody, and musky, with Kush notes and a little citrus brightness. Some flowers may lean more toward fuel and spice, while others feel more herbal and forest-like depending on the exact phenotype variations. If you like old-school OG flavors after dinner, King Louis XIII weed is exactly the kind of profile you may be searching for.
The terpene profile varies by sample, but King Louis is most often associated with:
These terpenes help shape aroma and may contribute to the overall experience through the entourage effect, although effects still depend on dose, tolerance and the exact chemical profile.
King Louis flowers are usually dense, green and resin-heavy, with orange pistils and frosty trichomes. Buds often look compact rather than airy. The overall plant structure is harder to predict because many breeders today claim to have selected their own cut or cross, so it can vary a lot between S1 versions, reproductions, or related hybrid crosses.
The reported effects of the King Louis strain are usually relaxing, sleepy, hungry, euphoric, and body-heavy. Many users describe a calm mental state that slowly settles into the body. At higher amounts, King Louis can become couch-locking, especially if you have a low tolerance to THC. It makes more sense for quiet evenings, movie nights, or winding down than for busy daytime plans. Some users report choosing King Louis weed for stress, pain, appetite, muscle tension, or difficulty sleeping.
Disclaimer: Cannabis effects vary from person to person. Strong THC strains like King Louis strain may feel overwhelming for some users and may worsen anxiety, low mood, or other mental health concerns. Always seek guidance from a healthcare professional before using cannabis for medicinal purposes.
Because the King Louis weed strain is usually high in THC, side effects are possible:
If you want to be on the safe side, always know the THC and CBD content of your weed. Choose a trusted source where legal, or use quantitative tests at home when reliable testing is available.
Growing information is difficult because Sirius does not currently sell King Louis seeds, and the original King Louis XIII is often discussed as a clone-only or cut-based cultivar. A King Louis week-by-week journal or King Louis grow report is useful if you know exactly which cut, breeder, or seed version is being grown.
In general, growers should treat the King Louis strain like a dense, aromatic, indica-leaning OG type. Airflow, humidity control, odor control, and pruning are important. If the plant becomes too leafy, cropping and lollipopping can improve light penetration and flower quality. Sirius has a guide to cropping cannabis cultivation techniques for growers who want more detail.
Published grow reports give the following estimates, although figures can vary between seed lines:
Indoors, focus on strong lighting, airflow, climate control, and smell management. In the Sirius online Growshop, growers can find grow tents, lighting, climate-control solutions, and current Growshop offers. For dense Kush-style flowers, ventilation and stable humidity are especially important.
Outdoors, King Louis-style genetics prefer warm, sunny, and relatively dry conditions. Choose a sheltered but airy spot, check regularly for pests and avoid overcrowding. For soil support, Sirius’ organic cannabis fertilizers can help provide the right NPK balance through growth and flowering.
Sirius does not currently have King Louis autoflowering or feminized seeds available. People looking for premium autoflowering cannabis seeds or feminized cannabis seeds can explore the Sirius online Seedshop.
