storing cannabis seeds long term

If, for example, you live in an area with very warm daytime temperatures and cool nights, try to protect your seeds from these changes and don’t store them outside in a shed or garage.

Older seeds often have an extra tough outer shell. Gently scratching this shell with some sandpaper can help moisture and warmth enter your seed at the time of germination. Try gently scarring your old cannabis seeds just before soaking to help them sprout.

EFFECTS OF HUMIDITY ON CANNABIS SEEDS

Before germinating your old seeds, try soaking them in carbonated water enriched with fulvic acid, germination booster, hydrogen peroxide, or gibberellic acid. For best results, use room temperature water and soak your seeds for 12 hours in a dark place.

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.

Cannabis seeds have three main enemies:

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.

As mentioned above, seeds require cold temperatures so they don’t lose their essence. Either freezing or refrigeration will do. However, when keeping seeds in the refrigerator, keep them as far back as possible so they won’t be exposed to any temperature changes when the door is opened.

WHY IS PROPER SEED STORAGE NECESSARY

If only being stored for a few months, cannabis seeds should do fine in a grip-seal bag, placed in a mason jar or some other type of airtight container. For more long-term storage, a vacuum-sealed package is a much more popular option. Many seasoned seed-savers like to add a food-grade desiccant to their package as well.

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.

Frequent inquiries from new growers are often related to cannabis seeds. How can they be stored safely? How long will they last in storage? Will they retain the same qualities as newer seeds? When stored appropriately, yes, you can grow prime cannabis plants with decade-old seeds, just as you could with seeds that are only a few months old.
