Flower Density Classification

Flower density classification refers to the compactness and mass distribution within cannabis inflorescences, typically categorized along a spectrum from loose/airy to dense/compact. This physical trait is determined by internode spacing, bract arrangement, and trichome concentration per unit volume. Breeders assess density as a structural characteristic influenced by genetics, light exposure, and environmental conditions during flowering. Dense flowers commonly present higher material yield per volume, while looser structures may facilitate airflow and reduce certain cultivation challenges. Density classification serves as a practical descriptor in breeding records and cultivation planning, alongside other morphological traits like bud size and calyx-to-leaf ratio.

Breeders select for density phenotypes based on cultivation goals and market preferences. Dense-flower genetics are often prioritized in breeding programs targeting high volumetric yield, while airier structures may be retained in lines bred for specific environmental resilience or processing characteristics.
