Some people who live in regions where there is a lot of cannabis activism and reform are currently stockpiling seeds of their favourite strains to grow when it’s legal in the future. Whatever your reason may be for having seeds, remember that taking care of them is one of the most important things you can do for your harvest.
A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.
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.
THE ATMOSPHERE IS KEY – COLD, DRY & DARK
With the correct method of storage, cannabis seeds could remain viable for 5-10 years! Read more about how to store seeds the best way!
Furthermore, seeds should never be exposed to direct sunlight and should be kept in a dark, dry place. Excess light and humidity can lead to premature germination. Ideally, 9% or less humidity is preferred.
When cannabis seeds are properly stored, most growers find the majority are still full of life after five years. Many growers have even grown high-grade cannabis with seeds up to 10 years old.
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.
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.
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.
How to store weed seeds?
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.
To prevent unused cannabis seeds from germinating or getting damaged, you have to store weed seeds in a cool, dark and moisture-free place.
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!
You must keep your seeds in a location that is cool, dark, and dry. It is best if you keep the seeds in their original packaging. When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients. This is a disaster because they ultimately won’t have the nutrients to germinate.
Once you enter medium-term storage (a few months), it is time to use an airtight container. Examples include a mason jar or Ziploc bag. Place this sealed container in the fridge. Remember that opening your fridge can cause significant temperature fluctuations. As a result, it is ideal if you have a second fridge that is seldom used.
What’s the Right Storage Temperature?
Once the goal is to store cannabis seeds for months rather than days or weeks, everything changes. You need an airtight container, which you should store in a fridge. Include a vacuum-sealed container if you plan to store the seeds for several months or longer.
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.
The best temperature to store your cannabis seeds at is between 43- and 47-degrees Fahrenheit. The lower the temperature, the less likely your seed is to germinate unexpectedly. Experienced growers tend to have special refrigerators to store their seeds. Ideally, your fridge is a no-frost model. If you can place the seeds in the fruit and vegetable section, that is even better.
