Plant Structure Overall Plant Height

Overall plant height refers to the vertical dimension of cannabis plants from base to apical tip at maturity, typically measured in centimeters or inches. This trait is governed by multiple genetic and environmental factors, including internode length, growth rate, and photoperiod sensitivity. Height classification systems commonly range from dwarf varieties (under 60 cm) through standard (60–150 cm) to tall phenotypes (over 150 cm). Breeders document height as a heritable characteristic influenced by both parental genetics and cultivation conditions such as light intensity, nutrition, and growing medium. Understanding plant height is essential for indoor cultivation planning, canopy management, and breeding programs targeting specific grow environments.

Breeders select for height to match production systems: compact plants suit space-limited indoor grows, while taller plants may improve yield potential in outdoor or greenhouse settings. Height correlates with internode spacing and branch architecture, making it a key structural trait in modern crop optimization.
