Plant Structure Short Internode

Short internode plant structure refers to cannabis plants exhibiting compact spacing between leaf nodes along the main stem and branches. This trait produces denser canopies with less vertical stretch, resulting in stockier, bushier phenotypes. Short internodes are commonly associated with indica-leaning genetics, though some sativa and hybrid lines also display this characteristic. Breeders working in this category often value the trait for indoor cultivation, where vertical space is limited, and for facilitating even light distribution across the plant canopy. The trait can be influenced by both genetic lineage and environmental factors such as light intensity and temperature.

Cannabis breeders intentionally select for short internode spacing to develop compact cultivars suited to controlled environments and space-restricted growing systems. This structural trait often correlates with flowering time, plant maturity rates, and yield distribution patterns, making it a practical selection marker in breeding programs.
