Ruderalis

Ruderalis is a third type of cannabis (alongside indica and sativa) characterized by its auto-flowering trait — flowering based on age rather than light cycle. Ruderalis is rarely consumed alone (low cannabinoid content) but is widely crossed with indica and sativa strains to create autoflower hybrids that suit home growers.

Example: Most autoflower seeds contain ruderalis genetics.

Etymology: From Latin 'ruderalis,' meaning growing in disturbed soil.
