Internode Spacing Wide

Wide internode spacing refers to the distance between leaf nodes along the main stem being relatively large, creating an openly structured plant architecture. Plants exhibiting this trait commonly develop fewer leaves per unit length of stem and often display a more linear, vertically-oriented growth pattern. This phenotype is frequently observed in sativa-dominant lineages and certain tropical cultivars where vertical growth was advantageous in competitive forest environments. Wide internode spacing can influence canopy penetration, light exposure to lower branches, and overall plant footprint in cultivation. Breeders document this trait as heritable and useful for designing cultivars suited to specific training methods or vertical garden systems.

Breeders working with wide internode spacing select for this trait when developing cultivars intended for high-density vertical cultivation, SCROG systems, or environments where airflow and light penetration are priorities. The trait's heritability makes it a stable target in multi-generational breeding programs focused on plant architecture optimization.
