Cultivation Phenotype Drift

Cultivation Phenotype Drift refers to observable changes in a cannabis plant's physical characteristics, aroma profile, and chemical composition when grown under different environmental conditions, even from the same genetic line. Factors such as temperature, humidity, light spectrum, nutrient availability, and growing medium can influence terpene expression and volatile compound production, resulting in phenotypic variation. This phenomenon is well-documented in cannabis breeding records and research, where identical genetics may produce noticeably different aromatic profiles across seasons or cultivation methods. Understanding phenotype drift is essential for breeders attempting to stabilize traits and for cultivators seeking consistent results. The trait is not inherent to the plant itself but rather reflects how genotype interacts with environmental variables. Careful environmental c

Breeders working to stabilize aromatic and morphological traits across multiple generations typically conduct side-by-side grows under controlled conditions to distinguish genetic stability from environmental influence. Recognizing and documenting phenotype drift helps identify which lineages maintain consistent expression versus those requiring stricter environmental parameters to reliably reprod
