How long do marijuana seeds last?

Marijuana seeds last the longest in the refrigerator. They should be stored in a cool, dark place and can be used within 16 months. If you're going to wait more than 16 months, it's best to put them in the freezer for future use. However, some suggest that seeds can last for years if stored in a cool, dark place.

The short answer is several years or up to 5 years, depending on the circumstances. Even though seed banks recommend planting weed seeds within a year of purchasing them, they can have a shelf life of up to five years if stored properly. Yes, that is, you store them in a stable environment without changes in temperature, high humidity and light. Or in other words, a cool, dark and dry place.

The ideal is to store them in an airtight opaque container, but you can also freeze them if you want. Old seeds take longer to germinate, but as long as their shell isn't damaged and they continue to look healthy, they should be good to use. Refrigeration can preserve seeds for several years or longer, but it's probably best to use them before this time passes. Freezing the seeds is possible, but it is necessary.

The germination rate of marijuana seeds naturally decreases over time. However, if properly stored, the seeds can last up to 5 years. However, in order for them to last that long, they must be of good quality and stored in a cool, dry, dark place. If you plan to store your seeds longer, you'll need a few more steps to protect the long-term viability of the seed.

Putting a cotton ball with the seeds before storing them can help absorb any additional moisture (which is why you often see small pieces of cotton in seed breeder packages). This method isn't foolproof (sometimes the seeds just don't want to germinate), but it's the most reliable way to know if your precious cannabis seeds are still alive and viable. Make sure your offer won't cost you and ensure the viability of your seeds when it's time to sow with proper seed storage. They will keep marijuana seeds out of the light and dry, so all you have to do is store them in a cool place.

However, you'll notice that older seeds take longer to germinate than fresh seeds and some of them may not sprout at all. Most seed producers agree that an average of three to six years is a maximum for viability, and each day the seed is stored decreases the chances of it germinating just a little. If you are storing seeds from a seed package where you didn't use all of the seeds, keep the package and put it in a Ziploc bag. If you're going to go to the trouble of storing cannabis seeds for the long term, then you need to make sure you store only good seeds.

Storing marijuana seeds is a great way to ensure that you always have your favorite strains on hand, as well as to keep yourself stocked with plants for the long term. Some seed banks deliver the seeds in a vacuum-sealed package that you can store them until they are ready to sow. Keep in mind that humidity and temperature are the two most important agents for having a quality marijuana seed storage system. Despite these challenges, it is still possible to successfully grow a plant from a cracked marijuana seed.

However, by keeping seeds at 38 degrees Fahrenheit stable and around 5% moisture, as well as airtight and out of light, your seeds can last up to 5 years or longer.
