Optimal Storage Conditions
- Store seeds in airtight containers to prevent moisture entry.
- Keep containers in a cool, dark environment, ideally 40–50°F (4–10°C).
- Use desiccants like silica gel packets to maintain low humidity (around 20–30%).
- Avoid repeated temperature fluctuations; consistent cold storage is key.
- Label containers with strain name and harvest date for easy rotation.
Long-Term Storage Tips
- Vacuum-sealing seeds can significantly extend shelf life.
- Freezing is possible for long-term storage, but ensure seeds are fully dry to prevent ice damage.
- Check seeds periodically for signs of mold or decay.
- Keep seeds away from light and heat sources to prevent premature aging.
