K.O. is a modern hybrid-indica whose exact origins are undocumented. While its lineage includes Nicole Kush, the broader ancestral history remains incomplete and no breeder information has been publicly confirmed. This lack of clear provenance is common for the variety, as consistent, verified records regarding its initial development or intent do not exist.

The terpene profile of K.O. is confirmed to be comprised of limonene, myrcene, caryophyllene, linalool, beta-pinene, pinene, humulene, bisabolol, camphene, ocimene, terpinene, and terpinolene, in that specific order of dominance. Its cannabinoid content features an estimated 11.9% THC, along with an estimated 0.08% CBG and negligible CBD levels. These compounds inform the sensory profile, though users should note that the potency values and chemical ratios are based on averaged data rather than batch-specific testing.

Physically, the plant reaches maturity in 55 days of flowering and offers a high yield, demanding a moderate level of grower expertise for successful cultivation in both indoor and outdoor environments. Consumers typically report effects that are both relaxed and focused, making the strain suitable for applications involving pain, stress, and sleep. No notable offspring have been recorded to date.
