best way to store weed seeds

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.

Cannabis seeds should be stored somewhere cold and frigid. Whether you store your seeds in a freezer, refrigerator, or even a cabinet or drawer, it’s important to leave them there until it’s time to germinate. Rapid temperature variations will destroy the genetic integrity of your seeds.

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

THE ATMOSPHERE IS KEY – COLD, DRY & DARK

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.

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.

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 best way to temporarily store weed seeds (several days, weeks or months) is to place the seeds in a dark, lockable (plastic) container in the refrigerator.

Please note: once you have decided to use the marijuana seeds, place the seeds in the box for 6 hours outside the refrigerator, so the seeds calmly reach room temperature.

To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.

Storing cannabis seeds for a short term

When storing cannabis seeds properly, your seeds remain fresh and viable. Curious how to take care over storing cannabis seeds, and how long you can preserve your weed seeds? Read on and learn how to store weed seeds!

Cannabis seeds can withstand very low temperatures, but air humidity and fluctuations in temperature should be avoided at all times. Keep in mind that marijuana seeds are living organisms. When the seed makes contact with water, the nutrients in the seed that trigger the germination process will be released.

Of course, it’s also possible that you have bought several cannabis seeds and that you want to keep a part for, for example, next year. The best way to store cannabis seeds for a long term is to freeze the seeds. Make sure you vacuum pack the seeds, place the seeds in a dark lockable (plastic) container and put them in the freezer. If done right, you can store your seeds for years.

Once you have received your ordered cannabis seeds, most growers start their grow right away. After all, your seeds are fresh, and you want to prevent the cannabis seeds from germinating in an uncontrolled way. However, if you can not or do not want to start with your cultivation immediately, it is important to store the seeds properly.

To keep humidity low, it is ideal to have some sealable containers on hand. To do this, a highly recommended option is to use Eppendorf tubes, a standard piece of laboratory equipment used for the preservation of liquid samples, and the very ones in which we provide our customers with our seeds.

Another threat that can ruin all your efforts are insects. Just one in your container is enough to render all the seeds inside useless. To prevent this it is advisable to spread diatomaceous earth where you store them. D.E. is a kind of sand with a fossilised algae base. It is inert and non-toxic, and functions as an invaluable natural insecticide. If you keep your seeds in your fridge with other foods, this will not be a good place to use this type of substrate. However, if you have a refrigerator just for this purpose, or a simple closet, you will be able to use this trick.

Humidity control via micro conservation in Eppendorf tubes

If you do not have any of these containers, you can always use some opaque and airtight plastic bottles, which will also do the trick. Inside, along with seeds, it is a good idea to place some dry rice or silica crystals, separated from them by means of a cotton ball or paper. These elements will absorb moisture from the atmosphere, which, depending on one’s location, can be around 25% or higher.

Note these two temperature limits to calibrate the range in which you operate. Keep in mind that the ideal temperature to store seeds is around 6 to 8° C. Hence, the most expert growers have a refrigerator just for this purpose, with low temperatures being constantly maintained. The same is true with regards to humidity: if you do not want your seeds to suffer any damage it is advisable to keep them in places with a relative humidity of around 20-30%.

They are where it all begins. The care you give your cannabis seeds will determine not only how your plants grow, but also the final results of your harvest. As we are dealing with a natural product that needs to develop, the conditions under which it is stored will have an impact on their subsequent yield. Thus, though marijuana seeds are quite robust and autonomous, if you want to avoid unwanted setbacks when you plant them, you should take steps immediately after obtaining them.
