Pheno Documentation

Pheno documentation refers to the systematic recording of phenotypic traits across cannabis plants grown from the same genetic line. Breeders and cultivators track observable characteristics—plant structure, leaf morphology, flowering time, resin production, aroma profile, and color variations—to understand how environmental factors and genetic expression interact. This practice is foundational to selective breeding, as it creates a repeatable baseline for identifying stable cultivars and understanding genetic potential. Documentation typically includes grow logs, environmental data, and detailed observations across multiple generations. Accurate pheno mapping helps breeders isolate desirable traits and inform future cross-breeding strategies.

Breeders rely on pheno documentation to distinguish phenotypic plasticity (environmental response) from true genetic variation. Detailed records across multiple seasons and grow environments enable breeders to identify which traits breed true and which require environmental control, directly informing line stabilization and cultivar selection.
