Altitude Selection
Altitude Selection refers to cannabis populations developed or maintained at specific elevations, where environmental pressures—including UV exposure, temperature fluctuation, and oxygen levels—shape genetic expression and plant architecture. Breeders working in mountainous regions have long documented that plants naturally selected at higher elevations often exhibit compact growth, enhanced resin production, and distinct terpene profiles compared to lowland counterparts. Lineage records from traditional growing regions in the Andes, Hindu Kush, and Himalayan foothills frequently report strains carrying these altitude-adapted traits. This classification is primarily of breeding interest, as it describes both a selection method and a set of phenotypic characteristics tied to environmental adaptation rather than a discrete genetic marker.

Breeders intentionally work with altitude-selected genetics to introduce hardiness, UV resilience, and efficient flowering under variable conditions. These populations provide valuable genetic diversity for developing cultivars suited to high-elevation or challenging outdoor environments.
