Low Internode Spacing

Low internode spacing refers to the distance between nodes on a cannabis stem being characteristically short, resulting in a dense, compact plant structure. This trait is commonly associated with indica-dominant genetics and certain landrace populations from regions with shorter growing seasons. Breeders working in this category often select for this phenotype to increase bud site density per unit height, which can optimize canopy management and yield efficiency in constrained growing environments. The trait influences plant architecture, light penetration patterns, and overall cultivation strategy, making it a relevant breeding consideration for commercial and breeding operations. Low internode spacing frequently appears alongside other morphological markers like broader leaf structure and shorter overall plant height.

Breeders select for low internode spacing to develop compact cultivars suitable for indoor production, sea-of-green (SOG) methods, and space-limited environments. This trait is often crossed into hybrid lines to reduce vertical stretch while maintaining or increasing flower production per plant.
