Inter Node Spacing

Inter-node spacing refers to the physical distance between leaf nodes along a plant's stem—a structural trait rather than a terpene, though often discussed alongside morphological characteristics in cannabis breeding literature. Plants with tight inter-node spacing (nodes close together) typically produce denser canopies, while wide spacing creates airier structures. This trait is influenced by genetics, light conditions, and growing environment, making it a key consideration in cultivation planning. Breeders working in different cultivation styles—indoor, outdoor, SOG systems—often select for specific spacing patterns to optimize yield and air circulation. Lineage records frequently report inter-node spacing as a stable indicator across generations, helping growers predict plant architecture before growth.

Breeders deliberately select for inter-node spacing to match cultivation methods: tight spacing for high-density indoor setups, wider spacing for outdoor resilience and light penetration. This trait is often paired with height potential and branch architecture when developing cultivars for specific growing systems.
