Louis XIII OG is a modern indica variety derived from its parent, Joe's OG Kush. As an easy-to-grow strain suited for both indoor and outdoor environments, it completes its flowering phase in 63 days and typically offers a medium yield. While it shares some genetic lineage with the broader OG Kush family, this specific expression is distinguished by its focused development profile.

The aromatic and flavor profile of Louis XIII OG is defined by its complex terpene composition, led by a primary dominance of myrcene, followed by limonene, caryophyllene, and humulene. This arrangement shifts into nuances provided by linalool, beta-pinene, and pinene, with further contributions from bisabolol, valencene, caryophyllene-oxide, and borneol. The sensory experience is rounded out by trace amounts of nerolidol, camphene, terpinolene, ocimene, gamma-terpinene, geraniol, and sabinene, creating a multifaceted profile.

As a THC-dominant cultivar, Louis XIII OG produces effects characterized by a sense of being relaxed, calm, and focused. These properties make the strain a common choice for managing pain, stress, and sleep difficulties. The strain's influence on the cannabis market is cemented through its notable offspring, which include Bourbon Cookies and Bourbon Sauce.
