Short Internodal Spacing

Short internodal spacing refers to the distance between leaf nodes on a cannabis plant stem being notably compact. Plants exhibiting this trait tend to develop a bushier, more horizontally-oriented structure with multiple branch points occurring in close proximity along the main stem. Breeders have worked with this characteristic for decades, as it can influence canopy density and light penetration within the plant structure. Lineage records frequently report this trait appearing in certain landrace populations and stabilized in various modern cultivars. The phenotypic expression is influenced by both genetics and environmental factors including light spectrum and growing conditions. Understanding internodal spacing is foundational to crop planning, canopy management techniques, and selective breeding programs.

Breeders working with short internodal spacing select for improved canopy architecture and space efficiency in controlled environments. This trait is often combined with other structural genes to develop cultivars suited to specific growing systems and yield targets.
