Seed Storage

Seeds carry on life processes, at a low rate, whilst dormant. Moisture they absorb from the air combines with stored nourishment within the seed to form a soluble food, which then combines with oxygen from the air to release water and heat. Too much moisture in the air will cause the seed to burn up its stored food too quickly producing excess heat which will further lower the seeds ability to germinate. The need is to keep these exchanges to a minimum during storage to prolong life in the seed.

6-9% moisture is ideal for long term storage of hemp seeds. A test for moisture levels shows that hard shelled seeds like hemp seeds shatter instead of mashing at around 8% moisture when placed on concrete and struck with a hammer.

Silica gel, often used in the drying of seeds, can also be used to help maintain stable moisture levels within a permanent storage container. Equal weights of silica gel to seed are used. In general hemp seeds weigh between 0.01 and 0.02 grams and our silica gel sachets contain 0.5g. We recommend seeds are kept in aluminium zip-lock bags and stored inside seed jars along with the correct amount of silica gel to maintain low moisture levels. Be aware that you can seriously damage seeds by reducing moisture levels too much, so do not use too much dessicant.

Temperature

Seeds can survive temperatures that would kill the parent plant as long as they are thoroughly dried. Excess moisture in seeds that are then frozen can potentially freeze, damaging the seed.

Seeds need to be stored in a cool or cold place. Therefore, locations at floor level are preferable to those nearer the ceiling which can be significantly warmer. However, for long term storage, placing seeds in the fridge or freezer is ones best bet, as long as moisture content of the seed and storage container is low and the container is air-tight. The ideal temperature in a refrigerator is around 4 o C.

A freezer is best for long-term storage of seeds although you need to make sure:

  1. You do not take the seeds out too much or for long enough for the temperature change to affect the seeds.
  2. When you want to remove seeds from the freezer, you leave the container closed whilst the seeds warm to room temperature or otherwise condensation will form on the seeds.

Light

Similar to moisture and temperature, light can help stimulate and support the germination process. And, just as many foods, pharmaceuticals and chemicals rapidly deteriorate when exposed to light, so also is seed viability and vigour affected by being exposed to light during storage.

Seed Storage Problems

Mildew/Mould

Seeds which have not been dried to the correct moisture content before being sealed in containers, can and frequently do rot. A simple test: after “drying” and placing in closed glass jars, the appearance of condensation on the inside of the jar within a few hours indicates the need for further drying. Silica gel should help with this.

Insects

Insects that may have escaped notice can wreak havoc on stored seeds. A few pinches of diatomaceous earth (DE) is a safe, inexpensive and non-toxic way of protecting seeds against insect damage. It doesn’t take much; just be sure to lightly coat all seeds before final sealing and storage. DE is available at most garden centres.

Rodents

Seeds which are not stored in glass or metal can provide a veritable banquet for mice and other small vermin. Make sure all seeds are kept in well labeled metal or glass containers.

Seed Storage 101: How to Store Cannabis Seeds

Not all of the seeds that you purchase always end up in the ground for planting the season that you purchase them, which means the left overs require storage. However, if they aren’t stored correctly, you risk losing that seed to environmental factors that could affect your crop – or maybe it won’t grow at all. This article is about how to correctly store your seeds until next season.

So you’ve just received your latest shipment of 25 seeds from your favourite seed bank—and you only plan to plant 5 or 10 of them this season; or you’ve just finished this season’s harvest and you’d like to store the seeds you’ve collected for your next crop … Proper storage of cannabis seeds is an essential aspect of ensuring the viability of future marijuana crops.

There are two types of seed categories:

  • Orthodox Seeds – these seeds enter a dormant stage and will survive drying;
  • Recalcitrant or Unorthodox Seeds – seeds that will not survive drying and are susceptible to desiccation injury.

Cannabis seeds are the orthodox type, or desiccation-tolerant, and can be prepared for long-term storage without risking instability.

Key factors to consider when storing seeds are environment and container. Environment is important because moisture levels, temperature, and light exposure all play a role in the stability of your seeds, along with oxygen and ethylene concentrations. The container you choose for storage plays an important role in that the proper environment will be maintained if you use the proper receptacle. Hand-in-hand, these factors help ensure the viability of your seeds for either long- or short-term storage periods.

Environment

Environmental factors that affect the viability of cannabis seed are:

  • Moisture – reducing moisture exposure ensures seeds won’t prematurely germinate or become mouldy.
  • Temperature – fluctuations in temperature can lower a seed’s longevity significantly.
  • Light exposure – light is required for germination; over-exposure may cause seeds to come out of their dormant stage and encourage tissues to mutate.
  • Ethylene concentration – ethylene is an important natural plant hormone; seeds begin to produce ethylene immediately after exposure to water or moisture (another reason low moisture conditions are necessary during storage).
  • Oxygen concentration – lowering oxygen exposure will reduce or prevent seed respiration during storage, thus deterring premature germination.

Frequently Asked Questions About Cannabis Seeds

It is important to dry your seeds gradually and thoroughly before storing them—although not to 0% moisture, as this can result in the death of a seed. During ripening and drying, cannabis seeds will prepare for dormancy by slowing or stopping most physiological processes. Ideal moisture percentage is 2-3% and can be achieved by placing a desiccant in the storage container with your seeds. (A desiccant is a hygroscopic substance that induces or sustains a state of dryness in its vicinity (draws out water). Commonly found pre-packaged desiccants are solids that adsorb water, e.g., silica gel packs. These can be found at Wal-Mart, Uline.com, or your local florist!). Rice is also known to be an effective desiccant, but should be replaced periodically. The use of a desiccant when drying seeds greatly improves their stability.

Keep cool, keep dark, and keep dry! Maintaining a constant environment with little or no fluctuation is vital to ensure the stability your stored seeds.

Storage Methods

The jury is still out on the best location for optimum storage results—each having pros and cons; here are the most common recommendations:

Cannabis Seed Storage Containers

If you need the store small to medium quantities of seeds or concentrates, you’ll want to invest in the best seed container you can get. Like other types of cannabis packaging, the myriad of options can be dizzying. Thankfully, 420 Packaging makes it simpler to get the right cannabis seed storage containers at a great price.

Your seed container must be air-tight. For long-term storage, glass packaging for seeds is the industry standard. Plastic seed storage containers can be an excellent choice for short- to medium-term storage. A water molecule can sneak through the pores in plastic cannabis seed storage containers. This factor only becomes an issue if other important factors aren’t attended to or if seeds are kept in the plastic seed container for too long. And Ziploc baggies are poor for storing marijuana seeds because they aren’t entirely air-tight and allow light and temperature fluctuations.

It’s also essential to have the seed holders and lids made from the same material. Glass and plastic expand and contract at different rates, letting in moisture and temperature changes.

It’s important to remember that cannabis seeds are alive and need to be kept safe and handled with care until they’re planted. Marijuana seeds are also expensive, so it’s imperative to ensure you have quality cannabis seed packaging. To protect your investment, you’ll need to know how to store them safely. If exposed to the elements and extreme temperatures, seeds will die.

How Do I Store Cannabis Seeds?

Cannabis seeds are natural, living things and should be handled with care. When stored correctly in quality seed storage containers, you can expect your cannabis seeds to remain viable for about five years or longer. After five years, germination rates tend to drop. However, some have had success growing plants from seeds that were ten years old or more.

Proper labeling is crucial for efficient cannabis seed storage if you’re storing several seed strains. Labels also add another protective layer to your cannabis seed packaging to help keep light exposure to a minimum.

Storing cannabis seeds with a desiccant inside your seed holders will maintain 2-3% moisture levels inside your air-tight seed container. Desiccants also absorb the

excess ethylene produced naturally during the aging process, extending the life of the seeds. Rice can be an effective desiccant, but it needs to be regularly replaced because it’s organic. Silica gel packs are reusable, saving you time and money.

Some folks place a layer of cotton or wool between the desiccant and the seeds to create a physical boundary between them. Our foam inserts for seed storage containers are even better. They help absorb any initial excessive moisture and ensure seeds are not physically disturbed.

Where you’re storing marijuana seeds can impact their viability and longevity. Your refrigerator is cool and dark, but moisture fluctuates whenever the door is opened and closed. Storage in the back of a fridge (where there is less moisture), with a desiccant in an air-tight seed container, is a viable option for seed stability and may adequately deter mold production.

Contrary to popular belief, freezing seeds destroys cells within the seed. There is special laboratory equipment that slowly brings down the temperature of the seeds to prevent damage, but it’s expensive, and most growers do not have this equipment. If you are determined to use the freezer, put the seeds in air-tight cannabis seed storage containers or vacuum-sealed bags with a food-grade desiccant satchel.

Storing marijuana seeds short-term is the easiest to accomplish. Select a cool, dark drawer or cupboard and ensure that the spot has a consistent temperature. The seed packaging still needs to be air-tight.

Many growers opt for foam canisters, mylar bags, or plastic containers for seed holders. The primary consideration is that the packaging keeps oxygen and water molecules out. Storing seeds for a few years in air-tight seed packaging at room temperature in a closet or closed cabinet is fine.

The best seed packaging for medium-term storage is an air-tight container like a mason jar, ziplock bag, or vacuum sealable container.

What Cannabis Seed Storage Containers Are Available?

420 Packaging offers a wide selection of hemp seed packaging options. We have a variety of hinged lid containers, small plastic tubes for concentrates and seeds, and child-resistant packaging for seeds.

Many customers prefer hinged lid cannabis seed storage containers simply because they don’t want to risk misplacing a screw-top lid.

Our hinged lid plastic vials for concentrate & seeds come in a wide variety. We offer sizes from 0.2ml to 1.5ml. You can also choose cannabis seed storage containers that are clear or from various colors.

How Do You Test A Seed Storage Container For Child Resistance?

Child-resistant plastic seed containers are tested and certified by the American Society for Testing Materials and CPSC. To qualify as child-proof seed vials, it must be “significantly difficult for children under five years of age to open within a reasonable time,” but “not difficult for normal adults to use properly.” The definition of “a reasonable time” is:

  1. Attempting to open the packaging takes enough time that the child gives up.
  2. The attempt to open takes enough time that a parent would find them and intervene.

That definition is from the Poison Prevention Packaging ACT of 1970. To be certified child-resistant by the ASTM, each seed storage container must undergo extensive testing with young children attempting to open the products. Our child-resistant packaging meets ASTM standards.

What Should I Keep in Mind for Cannabis Seed Storage?

Seeds are living organisms, and if not correctly cared for, they can germinate prematurely or die. Using the right seed holder for storing cannabis seeds means that you can preserve seeds for extended periods until ready for planting. Damaged seeds can’t germinate, but you also don’t want them to germinate while in storage.

To be effective, a cannabis seed storage container must be air-tight, moisture- and humidity-proof, and resistant to temperature fluctuations.

Eliminating exposure to light is the first and easiest consideration for your seed containers. Seeds are unlikely to germinate when stored in dark places. They can’t grow if they’re kept near a window too exposed to the sun. The nutrients get depleted, the seeds can’t develop once planted.

It’s best to store marijuana seeds is in cool conditions – 43°–47° Fahrenheit. The cooler it is (without freezing), the less likely your seed will be to germinate. Many growers use a “no frost” refrigerator.

The ideal environment for cannabis seeds is cold and dark with low humidity. Any fluctuations in these conditions put the seeds at risk. It’s best to keep air-tight seed storage containers sealed until the seeds are ready for planting. Exposed seeds are at risk to bacteria and pests.

When storing cannabis seeds, you need to carefully control relative humidity (RH) levels. If you have RH levels below 8%, your seeds become vulnerable to pests. Humidity levels above 10% can result in fungi developing. Levels above 60% cause wilting, drowning, and death.

The ideal RH range for short-term storage is 21–30%. Preserving seeds for extended periods means keeping them as dry as possible at 8–10%. Maintaining the proper RH level reduces the risk of pests while maintaining optimal humidity. RH levels below 8% drastically increase pest and insect activity around the seeds. Harmful fungi flourish in 12-14% RH levels and can begin to rot as it climbs to 18-20%. At 40–60% RH, seeds start germinating. These are the optimal levels for cultivating most strains of cannabis.
