Plant Sex

Plant sex in cannabis refers to the biological reproductive capacity of individual plants, with three primary categories: male, female, and hermaphrodite. Female plants produce the resinous flowers sought in breeding and cultivation, while males generate pollen essential for sexual reproduction. Hermaphrodite plants display both male and female reproductive organs, a trait that can occur naturally or be induced by environmental stress. Understanding plant sex is foundational to cannabis genetics, as it determines breeding strategies, seed production methods, and cultivation outcomes. Breeders carefully control pollination to create stable lineages, while growers typically select females to avoid unwanted seed development in harvested material.

Breeders use sex identification and sex control (through feminization techniques, environmental manipulation, or genetic selection) to manage crosses deliberately and develop consistent strains. Hermaphroditism is sometimes selected for in breeding programs but is typically avoided in commercial cultivation due to self-pollination risks.
