Internode Spacing Long

Long internode spacing describes cannabis plants that develop greater distance between successive leaf nodes along the stem. This trait is often associated with sativa-dominant genetics and equatorial landrace lineages, where extended branching patterns may have offered adaptive advantages in competitive growing environments. Plants exhibiting this structure typically require more vertical space and may take longer to fill a canopy compared to compact phenotypes. Breeders working with long internode spacing must account for structural support needs and adjust training or support systems accordingly. This architecture is frequently observed in heirloom and heritage lines, particularly those with documented Southeast Asian, African, or South American origins.

Breeders selecting for long internode spacing often target sativa-leaning hybrids where vertical growth and lower branch density are desirable traits. This phenotype can influence training methods, flowering time estimates, and final plant height projections in cultivation planning.
