Browse 507 classic cannabis seeds 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 classic cannabis seeds
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.
