“How do I store my cannabis seeds?” is one of the most frequent questions we receive at DispenseroO. Whether due to the onset of winter or limited grow space, sometimes you need to store your cannabis seeds until the right time. Fortunately, DispenseroO seeds can retain their viability for years with proper storage.

When it’s harvest time, think of cannabis seeds much like your buds—improper storage can lead to disaster. Unlike buds, however, the deterioration of cannabis seeds is less visible; yet, incorrect storage can lead to a significant reduction in their genetic potency.

Cannabinoid and terpene profiles can become compromised, reducing both flavour and effects. By following these storage techniques, you’ll ensure that your seeds stay ready for a reliable yield years later. Neglect proper storage, and you risk losing valuable genetic material packed inside each tiny seed.

1. Store your seeds in darkness, shielded from light

Two primary threats to your seeds are light and moisture. Let’s start with light. Exposure to light can initiate premature germination and interrupt the dormancy of seeds. A little ambient light here and there won’t ruin them, but they should never be in direct sunlight.

Sunlight contains UV rays that can damage the DNA stored inside the seed. Place your seeds in a lightproof box and store that box in a dark cupboard or drawer for added protection.

In nature, mature seeds are often kept in dark settings, such as buried under fallen leaves or stashed by animals like squirrels. Even birds consume seeds, temporarily concealing them from light in their stomachs. These natural storage environments remain dark, helping to protect the seeds from premature germination.

2. Keep your seeds dry and free from moisture

Humidity is one of the top killers of seed viability. Moisture and darkness combined can prompt seeds to sprout prematurely. Even slight dampness in your storage area can trigger unwanted germination, causing irreversible damage.

To control humidity around your seeds, use a dark box in a dry, enclosed area. To further reduce moisture, consider placing silica packets nearby. For every three seeds, a 0.5-gram packet is generally sufficient.

Some seed enthusiasts even use food-grade silica for extra safety, although this might be overcautious unless you’re applying it directly onto seeds, which isn’t recommended.

If you’re harvesting your own seeds from fertilised plants, make sure they’re completely dry before storing. Either remove the seeds from the buds and allow them to air dry on a paper towel with a fan, or dry them within the buds themselves.

3. Maintain a cool, dry environment

For optimal storage, keep your seeds at a temperature between 8 and 12 degrees Celsius (45–55 degrees Fahrenheit), as recommended by the DispenseroO FAQ. This temperature range is typically below regular indoor room temperature, so refrigeration is often required.

At DispenseroO, we use dedicated refrigerators set precisely to 8 degrees Celsius, exclusively for seed storage. While a standard home fridge is typically cool and dark, it can introduce excess moisture due to food storage, which can harm seeds.

If storing in your fridge, keep seeds away from any items that might emit moisture, such as fresh produce, and avoid placing them in the vegetable crisper, which is designed to retain humidity.

4. Ensure a consistent temperature

If you don’t have a dedicated refrigerator, place your seeds in the coolest, driest part of your home and avoid moving them frequently. Consistency in temperature is often more important than achieving a specific range.

Fluctuations in temperature can cause water molecules within and around the seed to expand and contract, which may damage the seeds over time. By maintaining steady conditions, you help preserve seed quality and viability.

5. Keep your seeds clean and pest-free

Cannabis seeds, like many other types, are edible, which makes them appealing to pests. While DispenseroO customers generally don’t order seeds for consumption, it’s essential to remember that insects and rodents find them equally tasty.

To protect seeds from pests, store them in a clean area without any items that could attract insects or rodents. Diatomaceous earth, a non-toxic powder, can be sprinkled around the storage area to deter insects. For rodent protection, use a metal container with a secure latch, preventing most rodents from accessing your seeds.

By following these steps, you’ll ensure your dispenseroO cannabis seeds stays viable and ready for a successful harvest whenever you’re ready to plant. Proper storage not only preserves your seeds but also protects the investment you’ve made in their unique genetics.
