Flower Structure

Flower structure refers to the physical morphology and density characteristics of cannabis inflorescences—how tightly or loosely the floral clusters pack together, bract arrangement, and calyx-to-leaf ratio. This trait is largely determined by genetics, though environmental factors like light intensity and air circulation influence final expression. Breeders working in this category often select for either dense, compact flowers valued in indoor cultivation, or more open structures that support airflow in humid environments. Structure affects drying time, trim efficiency, and breeding stability across generations. Understanding flower morphology is essential for developing cultivars suited to specific production methods and environmental conditions.

Breeders stabilize flower structure traits through selective crossing to achieve consistency in harvest quality and processing efficiency. Dense flower phenotypes are commonly selected in modern indoor breeding programs, while open structures are maintained in lines bred for outdoor or high-humidity conditions.
