Canopy Phenotypes

Canopy phenotypes refer to the structural and architectural expressions of cannabis plants—how they grow vertically, branch density, leaf spacing, and overall form. These traits are heavily influenced by both genetics and environmental conditions, with breeders selecting for specific canopy structures to suit cultivation methods, from compact indoor grows to sprawling outdoor gardens. Canopy morphology affects light penetration, airflow, yield distribution, and pest/disease susceptibility. Lineage records frequently report canopy characteristics alongside flowering time and terpene profiles, as plant architecture is a critical breeding consideration. Understanding canopy phenotypes helps cultivators predict space requirements and optimize growing environments. Common descriptors include "bushy," "stretchy," "columnar," and "compact."

Breeders working in controlled-environment agriculture often select for compact, lateral-branching canopies to maximize light efficiency and space utilization. Conversely, outdoor breeding programs may favor more expansive canopy structures that develop robust secondary and tertiary branching.
