Short Internode Spacing

Short internode spacing refers to the physical distance between leaf nodes along a cannabis plant's stem—specifically, when nodes occur in close proximity to one another. This trait is determined by genetic factors and growing conditions, with some cultivars naturally expressing compressed node spacing. Breeders working in indoor cultivation often select for shorter internodes to maximize vertical canopy density and light penetration in limited headroom. This structural characteristic is distinct from terpene chemistry but frequently appears as a breeding target in modern cultivar development, particularly for space-efficient phenotypes.

Breeders value short internode spacing for yield optimization in controlled environments, as it allows more flowering sites per unit height and reduces stretch during transition. This trait is often selected alongside canopy architecture traits to produce compact, bushy phenotypes suitable for SOG (sea of green) and other intensive cultivation methods.
