Internodal Distance Tight

Internodal distance refers to the spacing between leaf nodes along a cannabis plant's main stem and branches. A "tight" internodal distance—where nodes are closely spaced—results in a compact, bushy plant structure with shorter distances between successive growth points. This classification is often observed in indica-dominant cultivars and certain landrace populations adapted to specific growing environments. Tight internodal spacing can influence canopy density, light penetration patterns, and overall plant architecture. Breeders document internodal characteristics as a heritable trait useful for predicting mature plant form.

Breeders working toward compact phenotypes or indoor-optimized cultivars often select for tight internodal distance to reduce vertical stretch and maximize lateral branching. This trait helps achieve desired canopy structures without extensive training and can influence flowering site density and yield distribution patterns.
