Short Phenotype

Short phenotype refers to cannabis plants that express naturally compact, reduced-height growth characteristics, typically reaching 3-5 feet in mature height depending on growing conditions and cultivar. This trait is often polygenic, influenced by multiple genes rather than single-locus inheritance, making expression variable across seed populations. Breeders and cultivators document short phenotypes in both photoperiod and autoflowering genetics, though the trait appears more consistently stabilized in certain regional landraces and modern cultivars selected for indoor cultivation. The expression can be influenced by environmental factors including light intensity, nutrient availability, and growing medium, adding complexity to phenotype prediction and breeding selection.

Short phenotype selection is valuable for indoor growers managing canopy height and vertical space constraints, making it a key trait in breeding programs targeting commercial greenhouse and controlled-environment cultivation. Breeders working with compact morphology often cross short-phenotype parents to develop cultivars suited to space-limited production environments while maintaining yield pot
