KC 45
KC 45 is a modern, automatic strain derived from Brazilian sativa genetics. As a versatile variety suitable for both indoor and outdoor cultivation, it is noted for its ease of growth, reaching maturity within a flowering period of 63 days. While its yield is considered low, the strain is recognized for its foundational role in subsequent breeding projects, serving as a parent to both Brazilian Diesel Auto and KC 48 Auto.
The chemical character of KC 45 is defined by a terpene profile dominated by myrcene, followed by caryophyllene and limonene as secondary and tertiary components. These compounds work in concert to establish the strain's aromatic and sensory profile, providing a specific experience derived from the interaction of these three primary terpenes.
Regarding consumption, KC 45 is a THC-dominant strain that produces effects characterized by relaxation, happiness, and an uplifted mood. These therapeutic properties make it a viable option for individuals addressing concerns related to stress, pain, and sleep. Its established genetic influence continues through its notable offspring, maintaining its place as a functional entry in modern cannabis breeding.

Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: increases serotonin in prefrontal cortex + dopamine in hippocampus via 5-HT1A; Johns Hopkins 2024: significantly reduced anxiety vs THC alone.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
