Extended Internodal Spacing

Extended internodal spacing refers to the increased distance between successive nodes (leaf attachment points) along a cannabis plant's stem. This structural trait is commonly associated with sativa-dominant lineages and equatorial origins, where taller, more vertically-oriented growth patterns may have offered adaptive advantages. Breeders working with extended internodal spacing often report longer flowering cycles and greater vertical stretch during the transition to bloom. The trait influences canopy architecture, light penetration, and pruning strategies in cultivation planning. Extended spacing contrasts with compact or tight-nodal phenotypes more frequently seen in indica-dominant and high-latitude landrace genetics.

Breeders select for or away from extended internodal spacing depending on grow space constraints, desired plant height, and light distribution goals. This trait is frequently crossed or stabilized in breeding programs targeting specific canopy structures or production environments.
