vacuum packed marijuana seed for storage

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.

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.

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.

THE ATMOSPHERE IS KEY – COLD, DRY & DARK

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.

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.

A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.

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.

If you provide the perfect conditions, marijuana seeds can be stored for up to 5 years and still be viable. If you give them decent conditions and maintain those conditions (i.e. no major fluctuations in the environmental conditions), you can expect the seeds to still be good after a year or two.

When putting desiccant in the container with the seeds, it is best to keep the two separate. You can create a boundary between the weed seeds and the desiccant by using wool or cotton.

That is why it is best if you have a refrigerator specifically dedicated to the storage of seeds. Or at least a second fridge that rarely gets opened.

How Long Can You Store Cannabis Seeds?

A glass jar is an ideal container, but your seeds may also already be in a great container. If you bought them online and had the seeds sent in the mail, chances are they are already sealed up tightly. Unless you need to open the container with the seeds, you can just leave them in there.

It is always a good idea to label your seeds, especially if you are storing a number of different ones. But even if you are only storing a few seeds and they are all the same strain, we still recommend you label them. You may not remember what they even are a year from now. And if there are others in the house, it’s a good way to let them know not to disturb the seeds.

If you ordered your seeds from a top online seed bank, they probably arrived in sealed packaging. If you haven’t opened it yet, it is best to just leave them sealed in that package.

If a seed gets a steady supply of fresh oxygen, respiration can occur. This may lead to premature germination. To prevent this, store seeds in an airtight container. Inside a vacuum is ideal, but just somewhere that is sealed off is sufficient.
