To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.
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.
Storing cannabis seeds for a short term
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.
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.
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!
If you want to store your seeds for at least six months, use a vacuum-sealed container. You can achieve this effect by removing all the air from a Ziploc bag. There are also special vacuum-sealed containers available online. Put the sealed bag in a dark container and put it in the fridge.
You can ‘test’ your seeds once you have removed them from storage. Place them in water. If they sink, they should be fine. However, if they float, it is more likely that they are bad seeds. You can still try to germinate, but there is a greater risk of producing poor-quality cannabis, or else the seeds fail to sprout. You can keep floaters in water for approximately 72 hours to see if they sprout a tail.
Here is a quick overview of what will likely happen to cannabis seeds at different humidity levels:
Imagine paying $100+ for seeds, going to the trouble of storing them, only to find that insects ruin them.
If you only require short-term storage, a dark drawer or cupboard is sufficient. The most important thing, regardless of the duration of storage, is to avoid temperature and humidity fluctuations. Rapid variations in temperature, in particular, can destroy your seeds. If you live in a location with warm daytime temperatures and cold nights, avoid outside storage.
Also, you should note that modern fridges have low humidity levels. If the humidity is too low, your seeds will begin using up nutrients.
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.
