Plant Structure Overall

Plant structure overall refers to the fundamental morphology and architecture of cannabis plants—encompassing height, branch density, internode spacing, leaf blade shape, and growth pattern (indica-dominant, sativa-dominant, or hybrid expression). These traits are influenced by genetics, photoperiod sensitivity, and cultivation conditions, and serve as primary phenotypic markers in breeding programs and seed variety identification. Breeders select for specific structural traits to optimize yield per square meter, canopy management, flowering time, and environmental resilience. Understanding plant structure is essential for predicting how a cultivar will perform in different growing systems—from dense indoor canopies to outdoor field crops. Structure classifications remain foundational to modern cannabis genetics documentation, even as cannabinoid and terpene profiling have become increas

Cannabis breeders deliberately select for plant structure to match cultivation goals: compact, branching plants for SOG (sea of green) or SCROG systems; tall, open structures for outdoor production or air circulation; and specific internode lengths for space efficiency. Structural phenotypes are among the earliest visible markers used in F1 hybrid development and backcrossing programs.
