Plant Structure Internodal Spacing Wide

Wide internodal spacing refers to genetics where nodes (leaf attachment points) are spaced far apart along the main stem and branches. This structural trait is commonly associated with sativa-leaning lineages and photoperiod-responsive cultivars that express elongated vegetative growth patterns. Plants exhibiting this characteristic typically develop taller frames with more vertical distance between successive branching points. Wide spacing can influence canopy architecture, light penetration, and branch load distribution during flowering. Breeders working with this trait often select for it when developing cultivars intended for specific training methods or vertical garden systems.

Breeders leverage wide internodal spacing to create tall, open-structured plants suited to higher-light environments or SOG/screen-of-green cultivation. This trait is frequently crossed back into dense-structure lineages to improve airflow and reduce microclimatic pressure in controlled environments.
