Low Internodal Spacing

Low internodal spacing refers to the physical distance between leaf nodes along a plant's stem—in this case, a relatively compact arrangement. Cannabis plants exhibiting this trait typically develop nodes closer together, resulting in denser foliage and a more branched, bushy structure rather than tall, stretched growth. Breeders working in this category often select for this trait to improve canopy density, light penetration, and cultivation efficiency in indoor and space-constrained environments. Low internodal spacing is frequently associated with indica-type genetics, though it also appears in many balanced hybrids. This structural characteristic can influence training methods, nutrient distribution, and overall yield architecture in breeding programs.

Commercial cultivators and breeders value low internodal spacing for its potential to maximize light interception per plant and simplify canopy management in controlled environments. Selection for this trait is common in breeding lines developed for indoor cultivation, where vertical space optimization directly affects production economics.
