Plant Structure Open Structure
Open structure describes cannabis plants with loose, airy branching patterns and wider spacing between nodes, creating a less dense canopy. This phenotype contrasts with compact or bushy growth forms, allowing greater light penetration to lower branches. Open structure plants often exhibit longer internode distances and may develop taller, more vertical growth habits. Lineage records frequently report this trait in sativa-influenced genetics and certain landrace populations. Environmental factors including light intensity, humidity, and nutrient availability can modify expression of structural phenotypes during vegetative growth.

Breeders working with open-structure plants often prioritize them for outdoor cultivation where air circulation reduces mold pressure, or for canopy management in high-density indoor setups. This architecture can simplify pruning and maintenance protocols compared to dense-canopied varieties.
