Plant Height Range

Plant height range describes the vertical growth potential of cannabis cultivars, typically categorized as dwarf (under 3 feet), medium (3–6 feet), or tall (over 6 feet) phenotypes. Height expression is controlled by multiple genetic loci and significantly influenced by photoperiod, growing environment, and cultivation techniques. Breeders working in this category deliberately select for specific height thresholds to suit different production systems—compact varieties for indoor cultivation with height restrictions, while taller plants often excel in outdoor or greenhouse settings. Understanding height genetics is foundational for crop planning, as it directly impacts canopy management, yield density, and resource allocation. Historical lineages often show height consistency within certain families, making this trait useful for both breeding predictions and cultivation optimization.

Height selection is critical for developing cultivars adapted to specific growing environments. Breeders track height segregation ratios across generations to stabilize desired growth patterns and identify polygenic markers controlling vertical extension.
