Autoflowering Trait
The autoflowering trait refers to a plant's ability to transition from vegetative growth to flowering independently of photoperiod (day/night length), rather than requiring specific light cycles to initiate reproduction. This trait originates primarily from Cannabis ruderalis subspecies, which evolved in high-latitude regions with inconsistent seasonal light patterns. Autoflowering varieties flower based on age—typically 3–4 weeks after germination—making them distinct from photoperiodic (long-day or short-day) cultivars. Modern autoflowering genetics result from decades of backcrossing ruderalis germplasm into established indica and sativa lineages. The trait is controlled by recessive alleles at multiple loci, meaning homozygous autoflowering parents reliably produce autoflowering offspring.

Breeders incorporate autoflowering genetics to create cultivars suited to short growing seasons, consistent indoor environments without light control, and outdoor production in variable climates. Stabilizing the trait while maintaining desired cannabinoid profiles and terpene expression requires multiple generations of selection, as early ruderalis contributions often came with reduced potency and
