Growth Form Tall

Tall growth form describes cannabis plants that develop extended vertical structure with significant internode spacing between branch points. Breeders working in this category often select for sativa-dominant or sativa-hybrid lineages, which commonly express this phenotype. Plants with this growth pattern typically require more vertical space and longer flowering periods than compact varieties. This trait appears frequently in equatorial and tropical landrace genetics, where vertical growth helped plants compete for light in dense environments. Understanding growth form is essential for cultivation planning, as tall plants demand different canopy management and support systems than shorter phenotypes.

Breeders intentionally develop tall-form cultivars for outdoor production systems, breeding programs focused on sativa characteristics, and genetics designed for vertical training methods. Selection for extended internodes and upright branching helps create plants suited to specific growing environments and production styles.
