What Is Cannabis Ruderalis?

Cannabis ruderalis is a subspecies that evolved in the harsh climates of Central Russia and Central Asia. It adapted to short summers by developing the ability to flower based on plant age rather than light cycle changes. Pure ruderalis plants are very small (1-3 feet), low in THC, and fast-finishing. While not useful on their own for recreational or medical purposes, ruderalis genetics are invaluable in breeding, they are the source of the autoflowering trait found in all modern autoflower strains.

Frequently Asked Questions

What is ruderalis cannabis?
Ruderalis is a wild cannabis subspecies from Central Russia. It flowers automatically based on age, not light. While low in THC by itself, ruderalis genetics are the foundation of all modern autoflowering cannabis strains when crossed with indica or sativa genetics.
Can you smoke ruderalis?
Pure ruderalis has very low THC content and is not typically consumed recreationally. However, when crossed with indica or sativa genetics, the resulting autoflower hybrids carry the autoflowering trait alongside high THC levels and quality effects.
