How to Store Cannabis Seeds Long-Term? [Complete Guide]

They may not seem to be doing much, but seeds are still alive. Until you’re ready to cultivate them, treat them gently and store them safely. Don’t worry if you don’t know how to properly store cannabis seeds; we’ve got you covered.

Many people underestimate how much work goes into keeping marijuana seeds safe and secure. To put them in the elements and high temperatures will kill them.

Below, we’ll go through the best ways to store marijuana seeds, how long they last, and what impact environmental elements play in the  Germination process. We are ready to go now.

How to Store Cannabis Seeds

Living organisms exist in the form of seeds. Your pets can perish if you neglect them. It is possible to store cannabis seeds for a long amount of time if you use the appropriate ways for doing so.

First, you need to confirm that the environment is compatible with your chosen strategy. There are a number of things to keep in mind:

  • Light 
  • Humidity levels
  • Temperature fluctuations

When any of the above factors aren’t correct, it can cause your seeds to germinate early or wilt. 

Light Exposure

The first thing to think about when deciding how to preserve cannabis seeds is how much light they will be exposed to. When you store seeds in a dark environment, they are less likely to germinate. Roots can sprout if your seeds are kept near a window that is exposed to the sun’s rays.

Seeds that receive an excessive amount of light may be forced to expend their nutrients in order to live before germination. The seeds get weaker as a result of the exposure and will not grow if you sow them.

Humidity Levels

In terms of humidity and seed storage, it is important to keep the two factors in balance. Your seeds are subject to pests if your RH levels go below 8%. Fungi can grow at humidity levels above 10%, whereas levels above 60% cause wilting and mortality.

For short-term storage, a percentage of 21–30 per cent is recommended. A dryness of 8–10 per cent is required for the longer-term storage of seeds. The seeds are affected in diverse ways at various levels.

 Humidity level                                      Effects
Below 8%At these levels, any pests or insects around the seeds become active, reproducing and damaging them.
8–10%The risk of pests still exists, but it’s the optimal relative humidity (RH) for long term storing of cannabis seeds. 
12–14%Fungi flourish in these conditions, which harms the seeds and affects their ability to germinate later.
18–20%The seeds may sweat, and heating can cause them to rot.
20–30%These levels are ideal for storing cannabis seeds for short-term use.
40–60%When you increase the RH to 40–60%, seeds start germinating. These are also the optimal levels for cultivating most strains of cannabis.
80–100%These levels are too high for storing marijuana seeds. Within 12 hours, they’ll start drowning, wilting, and dying.

Temperature Fluctuations

The ideal temperature for storing marijuana seeds is 43°–47°F. You’ll have a harder time germinating your seed if the weather is colder. A “no frost” refrigerator is used by many gardeners. Fruit and vegetable aisles are the finest places to keep them.

Prior to sealing them, they must be vacuum-sealed. When it comes to cannabis seed storage, it’s safe to state that conditions like cold, darkness and low humidity are best. Some farmers employ a freezer or a dark location at room temperature in addition to refrigeration.

Your seeds are in jeopardy if these conditions change. It is imperative that you maintain your containers sealed until you are ready to plant them. The seeds are more susceptible to germs and pests when opened.

Choosing Containers: The Best Way to Store Marijuana Seeds

Choosing the right container is essential if you want to keep your cannabis seeds safe. Depending on how long you want to keep the items, you can choose from a variety of storage choices. Among the options available to growers are:

  • Ziplock bags
  • Mason jars
  • Plastic containers
  • Mylar bags
  • Vacuum sealable containers

How to Store Cannabis Seeds in The Long Term

Vacuum seal containers are the best way to keep cannabis seeds for longer than six months. Make certain that it’s dark in colour and that it blocks out as much light as possible.

In the back of your fridge or freezer, put it. Again, be certain that the relative humidity (RH) is at an optimum level. Maintain the moisture level and absorb ethylene with a desiccant. Uncooked rice or silica gel packs are common substitutes.

How to Store Cannabis Seeds in The Short Term

The simplest way to store marijuana seeds is in a sealed container for a limited period of time. A cool, dark cabinet or drawer is an option. Make certain that the temperature in the area remains constant. Containers must be airtight in order to function properly.

Foam canisters, plastic containers, and mylar bags are commonly used by cultivators. Because they need to restrict oxygen and water molecules from entering, this is the most important consideration.

Cannabis seeds should be kept in an airtight container for the foreseeable future, such as a mason jar, ziplock bag, or vacuum sealable jar.

You may make your seeds last longer by storing them in the refrigerator. Keep an eye out for low humidity levels, as some refrigerators may not have enough.

Method for Storing Cannabis Seeds

Drying the buds is the first step if you plan to collect seeds from them. Harvested buds should be kept for 14 hours in a humidor before being transferred to brown bags for 2-3 days.

For another week, put them back in the humidor box, and the mature seeds will begin to fall off. Long-term seed quality preservation is made easier with this drying and curing process. For those who bought their seeds from an established seed bank, this step is optional.

The Steps for How to Store Cannabis Seeds Are:

Step 1: Make sure all of your containers are clearly labelled for later use. As an added benefit, it reduces the amount of light being absorbed.

Step 2: Insert a desiccant and separate the seeds with a layer of cotton wool. So that the moisture may be absorbed and the seeds are not harmed, this step is necessary.

Step 3: Afterwards, remove and discard the cotton barrier and seal the container with your cannabis seeds inside. Till you’re ready to plant it, leave it where it is until you are.

How Long Can You Store Cannabis Seeds?

A few days to a few years is the range of time that you can keep cannabis seeds in your possession. Controlling environmental parameters with precision is essential, and the better you are at doing it, the longer they’ll live.

The length of time you may safely store marijuana seeds depends on a variety of factors, including the type of container you choose, the temperature, and the humidity.

How to Germinate Stored Cannabis Seeds

First, you need to make sure that the cannabis seeds you’ve stored are in good condition and are still viable. We want them to look dark and spherical and smooth at all times. You may not be able to get them to sprout if they are pale, white, and shrivelled.

To see if they work, simply drop one into a glass of water. It is more likely for seeds to germinate if they sink to the bottom. Even if a root does form on a floating plant, the marijuana it produces will be of inferior quality.

In the case of stubbornly preserved seeds, there are a few methods you can use.
