Node Spacing

Node spacing refers to the distance between leaf nodes (internodes) along a cannabis plant's main stem and branches. This trait is genetically influenced and affects plant structure, branching density, and final height. Compact node spacing produces bushy plants with closely-stacked foliage, while wider spacing creates taller, more open structures. Breeders often select for specific node patterns to suit cultivation environments—compact spacing is favored in space-limited indoor setups, whereas wider spacing may benefit from taller canopies in outdoor or greenhouse settings. Understanding a strain's characteristic node spacing helps growers predict final plant morphology and plan training strategies accordingly.

Breeders incorporate node spacing as a key morphological trait when developing cultivars for specific growing conditions or aesthetic goals. Selection for tight or loose internodal distances across generations produces stable, predictable plant architectures that influence yield structure, light penetration, and ease of canopy management.
