For short-term storage, place the seeds in a container with desiccant. Seal it, and place it in a cool, dark place.
If you purchase marijuana seeds and intend to use them almost immediately, you should have no issues. Even so, it is probably best to keep them away from direct light. In the short-term, a dark cupboard is sufficient as long as the temperature and humidity are reasonable.
Also, you should note that modern fridges have low humidity levels. If the humidity is too low, your seeds will begin using up nutrients.
Make sure your seeds remain away from light, as it can directly trigger germination.
If you don’t begin with great seeds, you can forget about producing a harvest of high-quality marijuana. A lot of growers seem to forget one simple fact: Your seeds are alive! Although cannabis seeds are fairly durable, improper storage can ruin them. If you’re paying $10-$20 a seed, losing a full batch is an expensive mistake.
To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.
Note: seeds that are stored in the freezer should be germinated immediately after you take the seeds out of the freezer. Do not let the seeds thaw first.
Storing cannabis seeds for a short term
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.
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.
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.
