Climate Zones

Climate zones refer to geographical and environmental conditions—temperature ranges, humidity levels, altitude, and seasonal light cycles—that influence terpene expression in cannabis plants. Different cultivars have been selected over generations to thrive in specific climate zones, from Mediterranean-style environments to high-altitude regions. Terpene profiles often reflect the ancestral climate pressures under which a strain's lineage developed; plants bred for cooler climates may emphasize different volatile compounds than those adapted to hot, dry conditions. Understanding climate zone associations helps breeders predict which parent lines are likely to produce stable, consistent terpene expression under target cultivation conditions. Climate adaptation is not a terpene itself, but rather a framework for understanding how environmental selection shapes the full aromatic and chemica

Breeders use climate zone data to select parent plants likely to express desired terpene profiles under their specific growing conditions, and to identify geographic landrace genetics that carry climate-adapted traits. Crossing cultivars from different climate zones can introduce genetic diversity in terpene production and environmental resilience.
