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.
How to store weed seeds?
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.
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.
To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.
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.
These are small cylindrical containers with conical bottoms, made of polypropylene, and with hermetic seals. With this method of micro conservation the containers full of seeds are protected individually, in such a way that, even if there are variations in the outside atmosphere, inside the container the humidity conditions are constant.
Run from the light
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%.
To ensure this we place small pearls of silica gel inside the tubes so that, even if the outdoor humidity rises, or the temperature varies, we can be confident that the air is completely dry inside. The cap of the Eppendorf guarantees that no humidity gets in, but the silica gel also ensures that, if any were to penetrate it by accident, it would be immediately absorbed by this material.
It may seem obvious, without a doubt, but don’t forget to label the different strains you have. Once you store the seeds in their containers you should only open them to plant them. It is not advisable to open and close the container you are using, as the protection your seeds are provided is immediately lost once it is opened, and fluctuations in temperature and humidity can be highly detrimental.
