do cannabis seeds need to be refrigerated

For long-term storage, it’s best to keep your seeds in a sealed container inside the fridge. Remember that opening the door of your fridge can actually cause some pretty dramatic temperature shifts. If you happen to have a second fridge that gets used less often than the one in your kitchen, use that one to store your seeds.

Yes, cannabis seeds can be stored in the freezer. The lower the temperature, the slower they decline. However, it’s usually not necessary to freeze your seeds. Meet the conditions we outlined above, and you should be able to preserve your seeds for up to five years and still get a high germination rate.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

The ridge is the slightly elevated side of your seed. Like other parts of the shell, this ridge can become extra tough over time. Removing it gently with a sharp Stanley blade can help your seed sprout.

Again, whenever possible, keep your seeds in their original packaging. If you do open a pack of seeds and have leftovers, transfer the extra seeds directly into a sealed airtight container.

For short-term storage, a dark cupboard or drawer with stable temperatures is usually fine. Try to keep your seeds out of areas of your house that are susceptible to the natural temperature changes of your local environment.

Some people who live in regions where there is a lot of cannabis activism and reform are currently stockpiling seeds of their favourite strains to grow when it’s legal in the future. Whatever your reason may be for having seeds, remember that taking care of them is one of the most important things you can do for your harvest.

Furthermore, seeds should never be exposed to direct sunlight and should be kept in a dark, dry place. Excess light and humidity can lead to premature germination. Ideally, 9% or less humidity is preferred.

WHY IS PROPER SEED STORAGE NECESSARY

It’s also important to note that when freezing seeds, every time they are thawed and refrozen, they become less viable. Both freezing and refrigeration can also lead to excess moisture, so that’s something that needs to be monitored closely.

With the correct method of storage, cannabis seeds could remain viable for 5-10 years! Seed storage is important for many reasons. Someone who just created their own, high-quality genetics, may want to keep the seeds to reproduce the strain.

When cannabis seeds are properly stored, most growers find the majority are still full of life after five years. Many growers have even grown high-grade cannabis with seeds up to 10 years old.
