Canopy Density

Canopy density is not a terpene, but rather a plant structure characteristic describing the thickness and leaf coverage of a cannabis plant's upper foliage layer. Breeders working in cultivation genetics often select for specific canopy density traits to optimize light penetration, airflow, and yield potential in different growing environments. Dense canopy phenotypes are commonly associated with compact, bushy growth patterns, while open canopies allow greater air circulation and light reach to lower branch sites. Lineage records frequently report canopy density as a secondary trait influenced by internode spacing, leaf size, and branching architecture. Understanding canopy density is relevant to breeding programs focused on indoor cultivation efficiency, outdoor resilience, or phenotype consistency across generations.

Breeders select for canopy density based on target cultivation methods—dense canopies for space-limited environments, open canopies for humidity control or outdoor growing. This trait often co-segregates with growth rate and final plant architecture, making it a practical selection criterion in F2 and backcross populations.
