The phenotype of cannabis is a term used to describe the plant's physical characteristics. This includes height, colour, aroma, potency and the plant’s level of resin production.

The phenotype, or physical characteristics, of cannabis is determined by a combination of two main factors: the environment in which it is grown, and its genotype, or genetic coding. Physical expressions like aroma, appearance, height, potency and production of resin are all dictated by the plant's phenotype.
