Thin Leaf Phenotype
The Thin Leaf Phenotype describes cannabis plants expressing notably narrow, elongated leaflets compared to broader-leafed counterparts. This trait is commonly associated with sativa-dominant genetics and plants adapted to higher-light, equatorial growing regions. Thin leaves often correlate with increased internode spacing and a more open plant architecture. The phenotype appears across multiple strain families and is frequently observed in landrace populations from Southeast Asia, Colombia, and Central Africa. Growers and breeders recognize thin-leaf expressions as a structural marker, though leaf morphology alone does not determine cannabinoid or terpene profiles.

Breeders working with sativa-lineage genetics often select for or against thin-leaf traits depending on cultivation environment and desired plant structure. Thin-leaf phenotypes typically require longer flowering times and more vertical space, influencing breeding decisions for indoor versus outdoor production systems.
