Reduced Internode Spacing

Reduced internode spacing refers to a plant structure trait where nodes (leaf attachment points) are positioned closer together along the stem, resulting in a more compact, bushy plant architecture. This characteristic is often naturally present in indica-dominant genetics and select cultivars bred for controlled-environment cultivation. Breeders have selectively worked with this trait across multiple lineages, as compact morphology can influence canopy management, light penetration, and space efficiency in production settings. Internode length is primarily controlled by genetic factors, though environmental conditions including light spectrum, intensity, and plant spacing can modulate expression during growth. Understanding this structural variation is foundational for growers selecting breeding stock or planning cultivation strategies, as it directly affects plant form independent of f

Breeders working with reduced internode spacing focus on maintaining this trait across generations to stabilize compact plant types suitable for specific growing environments. This structural characteristic has been integrated into many modern cultivars to support consistent canopy architecture and facilitate trellising or scrogging techniques.
