Inter Nodal Length

Internodal length refers to the distance between successive nodes (where leaves and branches emerge) along a cannabis plant's stem. Breeders recognize two primary phenotypes: compact growth with short internodes, and stretch growth with elongated internodes. This trait is highly heritable and influenced by both genetics and environmental factors like light intensity and photoperiod. Compact cultivars are often favored for indoor cultivation due to reduced vertical space requirements, while some breeders maintain longer-internode lineages for specific garden environments. Internodal length variation appears across most modern strain families and remains a fundamental selection criterion in breeding programs.

Breeders actively select for internodal length to optimize plant structure for target cultivation methods. Shorter internodes enable higher plant density and more efficient canopy management indoors, while longer internodes may improve air circulation in dense outdoor or greenhouse settings.
