Thin Leaf Pheno
Thin Leaf Pheno refers to cannabis plants expressing noticeably narrow, elongated leaflets—a morphological trait influenced by genetics and environment. This phenotype is commonly observed in sativa-dominant lineages and certain landrace populations, particularly those from equatorial and tropical regions. Thin leaves are often associated with faster water transpiration and lighter canopy density compared to broad-leaf phenotypes. The trait appears across many modern hybrids but is most consistent in pure or stabilized sativa lines. Breeders working with thin-leaf genetics often report these plants respond well to high-light environments and longer photoperiods.

Breeders select thin-leaf phenotypes for specific cultivation goals, including improved light penetration in dense canopies and reduced fungal pressure in humid climates. The trait is frequently crossed into hybrid programs targeting tropical or outdoor-adapted cultivars.
