Leaf Ratio Phenotypes
Leaf ratio phenotypes describe the visual proportion of leaf surface area relative to flower density and bud structure within cannabis plants. Breeders categorize strains along a spectrum from "leafy" phenotypes—characterized by larger fan leaves and more vegetative expression—to "dense" phenotypes with compact flowers and reduced foliage. This trait is often polygenic, influenced by both genetic inheritance and growing conditions including light intensity, temperature, and nutrient availability. Lineage records frequently report that Sativa-dominant crosses tend toward higher leaf ratios, while Indica-dominant lines commonly exhibit tighter, less leafy structures. Understanding leaf ratio is relevant for cultivation planning, trimming labor, and breeding selection criteria.

Breeders working in this category use leaf ratio phenotypes to optimize yield efficiency and harvest processing. Selecting for denser phenotypes can reduce post-harvest trimming labor, while maintaining some leafy expression supports photosynthetic capacity during growth.
