King Louis XIII
The undisputed king of OG Kush phenotypes—celebrated for its pungent pine-gas aroma and heavy-hitting narcotic effects.
What is King Louis XIII?
King Louis XIII is a legendary Southern California staple that represents the pinnacle of OG Kush breeding. Unlike many modern crosses, King Louis is a "clone-only" cut, meaning true versions of this strain can only be propagated via cuttings from a mother plant. It is widely considered one of the most potent and aromatic expressions of the OG lineage.
Naming a strain after a French monarch known for luxury is fitting—this cultivar offers a "royal" experience characterized by extreme resin production and a flavor profile that combines earthy musk with an aggressive jet-fuel finish. While its exact origins are debated, its dominance in the SoCal cannabis scene for decades has cemented it as a must-have for any serious OG enthusiast.
Terpene Profile
The King Louis XIII terpene profile is loud and unmistakable. It hits the nose with a sharp, astringent pine scent followed by deep, damp earthiness. The "gas" factor is high, leaving a lingering petrol-like aftertaste that OG lovers crave.
Growing King Louis XIII
Growing the "King" requires some experience. Like most OGs, it can be finicky, exhibiting a "viny" growth habit with significant stretch during the first three weeks of flower. It requires sturdy trellising to support its dense, golf-ball-sized nuggets that can easily weigh down branches.
Key Growing Tips
-
SupportDouble trellising is mandatory to prevent branches from snapping under the weight of the resinous flowers
-
FeedingIt is a heavy feeder but sensitive to nitrogen burn; focus on Cal-Mag and Phosphorus during flower
-
AirflowDue to extreme bud density, maintain low humidity and high airflow to prevent botrytis (bud rot)
This strain thrives in a Mediterranean climate. If growing indoors, keep your day/night temperature swings tight to maintain the classic lime-green OG color.
Flower Quality & Resin
King Louis XIII is a **connoisseur's flower**. While its yields may not compete with commercial "cash crops," the quality of the resin and the shelf-presence of the finished flower are unrivaled. The buds are typically bright lime green with thick, orange pistils and a frost coating that looks like it was dipped in sugar.
Effects & Experience
The **King Louis XIII effects** are legendary for their ability to "shut down" the day. This is a classic indica-dominant experience—physical, heavy, and deeply relaxing. It is widely recommended for evening use as it typically results in a powerful "couch-lock" and eventually, deep sleep.

Frequently Asked Questions
Technically, no. The true King Louis XIII is a "clone-only" strain. Any "seeds" sold under this name are either S1s (selfed seeds) or crosses made by breeders attempting to replicate the original profile.
King Louis is generally considered more "pine-forward" and physically sedative than SFV OG or Tahoe OG. It also tends to have a tighter, rounder bud structure compared to the chunkier Ghost OG.
Due to its high terpene content and expansion in the lungs, it is best enjoyed via clean glass or a dry herb vaporizer to truly experience the pine and fuel notes without the mask of paper.
Only for the most experienced users with high tolerances. For most, King Louis XIII will cause significant lethargy and is better suited for post-work relaxation or bedtime.
