Node Spacing Internodal Length

Node spacing, or internodal length, refers to the distance between successive nodes (leaf attachment points) along a cannabis stem. This is a structural trait controlled by genetics and environmental factors, not a terpene, but it significantly influences plant morphology and breeding strategy. Shorter internodes produce bushier, denser canopies; longer internodes create more open, elongated structures. Breeders select for specific node spacing to optimize yield potential, light penetration, and ease of cultivation. Internodal length is commonly associated with indica-leaning genetics (shorter nodes) versus sativa-leaning genetics (longer nodes), though the trait exists on a spectrum across modern cultivars.

Breeders use internodal length as a key phenotypic marker when stabilizing cultivars for commercial indoor or outdoor production. Selecting parent plants with desired spacing patterns allows control over final plant architecture, canopy density, and flower site distribution.
