Properly storing and caring for cannabis seeds is crucial to maintaining their viability. Here’s a complete guide for beginners:
Storage:
- Avoid Heat and Light: Store seeds in a dark, cool environment. Exposure to heat and light can degrade them.
- Temperature and Humidity: Ideal storage temperatures are between 43-47°F (6-8°C) with humidity around 20-30%. Too much moisture can cause mold, while too little can dry the seeds out.
- Containers: Use airtight, food-safe containers such as mason jars or vacuum-sealed bags for long-term storage. Adding a silica gel pack helps absorb excess moisture.
Viability Timeframes:
- Short-Term: Seeds stored in a cool, dark place without moisture can remain viable for up to a year.
- Long-Term: Seeds stored in optimal conditions (cool and dry) can last up to 5 years or more, though viability gradually declines over time.
Germination Methods:
- Wet Paper Towel Method:
- Place seeds between two moist paper towels and cover them with a plate. Store in a warm, dark spot.
- Check daily to keep towels moist, and within 24-72 hours, roots will begin to emerge.
- Soaking in Water with Peroxide:
- Place seeds in a glass of water with a few drops of hydrogen peroxide. Soak them for 12-24 hours.
- This method helps soften the shell for quicker germination.
- Rapid Rooter or Root Riot Plugs:
- Place seeds directly into the moist plug. Ensure they are in a warm, humid environment until sprouted.
- Plugs offer a great oxygen-to-moisture ratio for healthy root development.
- Aeroponic System:
- Place seeds in a moist aeroponic root chamber to encourage root development in a highly oxygenated environment.
- Great for hydroponic growers, this system promotes rapid growth and prevents overwatering.
- Direct Planting into Soil:
- Sow seeds directly into a light, well-draining soil mix designed for seedlings.
- Keep the soil moist and warm (around 70-75°F), and ensure sufficient light for sprouting. Avoid heavy fertilizers in the early stages.
Best Practices:
- Temperature and Humidity Control: Ensure stable temperatures and humidity during germination. Avoid fluctuations that may damage delicate sprouting seeds.
- Gentle Handling: Avoid touching the seed’s taproot when moving germinated seeds to prevent damage.
- Patience: Seeds can take anywhere from 1 to 10 days to sprout, depending on the strain and method.
Following these guidelines will give you the best chance for your cannabis seeds stay viable and produce healthy plants for successful cultivation.
