Open Nodal Spacing
Open nodal spacing refers to cannabis plants that develop internodes—the stem segments between leaf nodes—with noticeably larger distances between them. This trait is influenced by genetics, light exposure, and growing conditions, though some cultivars consistently express wider spacing across environments. Breeders working in this category often observe open nodal spacing in sativa-dominant and equatorial landrace lineages, where extended stem length between branch points is common. The opposite trait, compact or tight nodal spacing, is frequently seen in indica-influenced genetics. Both expressions affect plant architecture, canopy structure, and cultivation logistics.

Breeders select for open nodal spacing when designing cultivars intended for tall-growing, vertical-canopy strategies or specific environmental conditions. Conversely, compact spacing is prioritized in breeding programs targeting limited-height operations or dense canopy management.
