Ruderalis Cannabis Seeds USA, Wild Cannabis Genetics
Ruderalis is the wild ancestor of autoflowering cannabis. Originating from Central Russia and Central Asia, these genetics carry the autoflowering trait that modern breeders have incorporated into popular strains. Pure ruderalis strains are compact, hardy, and flower based on age rather than light, the foundation of every autoflower in our catalog.

Browse 422 ruderalis and filter by seed-to-harvest time, strain type, difficulty, THC, expected effects and flavor. Product specifications are breeder-reported unless otherwise noted and may vary by environment and growing method.
How to choose ruderalis
Start with the factor that matters most for your setup: total growing time, available height, experience level, expected yield, cannabinoid profile or preferred flavor. Compare the complete strain specifications rather than choosing on THC percentage alone.
| Your priority | What to compare |
|---|---|
| A faster harvest | Seed-to-harvest time, not flowering time alone — they are different measurements |
| A small space | Expected height, stretch during bloom and recommended container size |
| A first grow | Difficulty rating, and how sensitive the cultivar is to feeding and training |
| A bigger yield | Indoor and outdoor yield ranges, and the environment the figure assumes |
| Potency | Breeder-reported THC and CBD |
| A particular experience | Cannabinoids, terpene profile and customer reports |
| Growing outdoors | Total lifecycle, climate suitability and your local season length |
Published THC, yield, height and finish times are estimates, not guarantees. Results vary with phenotype, environment, lighting, nutrition, container size and grower experience.
Ruderalis guide
Overview
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.
