Inter Nodal Spacing

Inter-nodal spacing refers to the distance between nodes (leaf attachment points) along a cannabis plant's stem. This trait is genetically influenced and varies considerably across different cultivars and strain families. Compact inter-nodal spacing produces dense, bushy plants with closely-stacked branches, while wider spacing results in taller, more open plant structures. Breeders often classify plants as 'tight-nodded' or 'loose-nodded' based on lineage records and observed phenotypes. This architectural trait has no direct relationship to cannabinoid or terpene content, but significantly influences canopy density, light penetration, and cultivation management decisions.

Breeders working in controlled-environment cultivation frequently select for tighter inter-nodal spacing to maximize yields per square meter and reduce stretch during vegetative growth. Conversely, outdoor breeders or those targeting high-yield phenotypes may work with looser spacing to improve airflow and reduce disease pressure in dense canopies.
