There are plenty of If you have some cannabis seeds but are not ready to plant them yet, you need to know how to store them properly. Here's our complete guide. Knowing how to properly store your cannabis seeds is essential for any grower, beginner or expert. Here are a few tips from Seedsman.

6 Effective Ways To Store Cannabis Seeds The Right Way

Following the legalization of Cannabis , many people are now opting to use it for recreational and medicinal purposes. There are plenty of Cannabis products users can purchase to serve their needs in the market.

Notably, some users prefer growing their Cannabis instead of purchasing it because it helps them watch how the seeds germinate and saves them the expense of buying Cannabis frequently. You can get various kinds of Cannabis seed strains depending on your tastes and preferences. However, you may decide to purchase female cannabis seeds but not plant them immediately. For beginners, they may lack knowledge on effective ways of storing seeds, but there are plenty of ways which include;

Glass jars

Buyers who want to store their seeds for long-term purposes can use glass jars because they don’t allow any amount of water to get inside. The jars come in large sizes, making them suitable for storing the gorilla zkittlez auto flower with 20 thc in large quantities. You can place a desiccate pack inside the jar to regulate humidity. Moreover, you can also use cotton balls to separate the pack from the seeds and absorb excess moisture that may damage the seeds.

You need to seal the jar using a tight cap or wrap the jar with an opaque cloth; this method allows you to store your seeds for many years.

Paper envelopes

If you want to store your Cannabis seeds for a short time, you can place them in envelopes. You can use a standard mailing envelope. However, you should ensure the envelope is thick to protect the seeds from light.

You can keep the seeds in a dark place where there is no light which is an agent of germination, to make the seeds stay dormant and prevent them from sprouting . Moreover, you can label the envelope with the strain’s name, the storage date, and the number of days you are storing the seeds.

If you want to ensure your seeds are incredibly safe in the envelope, you can sprinkle grains of rice or get a desiccant pack to regulate humidity. You must ensure you keep the envelope indoors to prevent bad weather from affecting it.

Mylar bags

If you don’t want to use a glass, you can use Mylar bags to store your seeds for a long time. However, you should ensure the bags are thick and get a desiccant pack to ensure the seeds are in the proper humidity and no light can penetrate inside. The bags are resistant to bad temperatures, making your seeds safe.

Vacuum sealed bags

Alternatively, you can store your Cannabis seeds in Vacuum sealed bags. They are completely sealed and prevent any Oxygen from getting into contact with seeds. The vacuum-sealed bags are suitable to store many seeds.

You can decide to use the vacuum-sealed bag on its own, or you can place it inside a small container. Both methods are effective, and your seeds will remain dormant for the set time.

Refrigeration

You can store your seeds in the refrigerator for a long time. However, you need to ensure your refrigerator does not spoil your seeds. Before placing your seeds in the refrigerator, you need to put them in plastic bags resistant to cool temperatures.

Notably, users need to ensure their refrigerator does not allow any light to penetrate inside since it may be harmful to the seeds.

Storage pot

You can store your Cannabis seeds temporarily in a storage pot with an airtight lid. There are a variety of pot sizes that can fit all your seeds. Moreover, you can label the pots with the name of your strains so that you can easily distinguish them.

Preferably you need to place the storage pot in a cool place to prevent heat from harming your seeds. You can also use a desiccant pack and cotton to protect your seeds from humidity. No air should get into the pot since it will prevent the seeds from getting dormant.

Other ways you can store your Cannabis seeds

  • Burying your seeds. Although it may sound strange, you can store your seeds by drying them before planting them. The temperature underground is cool, enabling the storage process to be smooth.
  • Plastic bags. You can use Ziplocs in storing your Cannabis seeds for a short period.
  • In a dark basement: If you lack a refrigerator, you can store your seeds in a cool dark underground basement.

Conclusion

If you’re not planning on storing feminized weed seeds for a long time and will use them soon, there won’t be much of a problem with storage. But it is still better to store them away from direct light. In that case, a dark closet will be enough if the temperature and humidity are acceptable. You can use all the above ways in storing your seeds to enjoy all the benefits of Cannabis and its farming in the future. However, you need to ensure that heat, light, and humidity factors do not affect your seeds. You can research other alternative methods you can use in preserving your seeds. Cannabis farming experts can also help you know the suitable way of storing the strain you want.

How to Properly Store and Preserve Cannabis Seeds [Explained]

If you don’t begin with great seeds, you can forget about producing a harvest of high-quality marijuana. A lot of growers seem to forget one simple fact: Your seeds are alive! Although cannabis seeds are fairly durable, improper storage can ruin them. If you’re paying $10-$20 a seed, losing a full batch is an expensive mistake.

Before your marijuana seeds germinate, they are in a similar state to animals when they hibernate. Like all living organisms, your seeds can die if you don’t take care of them correctly. The good news is that cannabis seeds can last for five years after harvest with proper storage.

In this guide, we outline how to store and preserve your cannabis seeds. We focus on the following:

  • Light
  • Temperature
  • Humidity
  • Storage
  • Insects & Pests
  • Germinating old seeds

Keeping Light Away from Your Marijuana 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.

When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients.

Make sure your seeds remain away from light, as it can directly trigger germination.

What’s the Right Storage Temperature?

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.

Another option is to freeze the cannabis seeds. If you go down this route, please ensure that you vacuum pack them first. Then put them in a dark container. Also, it would help if you germinated these seeds immediately once they come out of the freezer. Don’t allow them to thaw first.

What About Humidity?

Here is a quick overview of what will likely happen to cannabis seeds at different humidity levels:

Your cannabis seeds need a certain level of moisture for germination. If the humidity level gets too high, your seeds will rot in storage. An extremely low level of humidity of around 8-10% is suitable only for long-term storage. If it drops below 8%, you offer any insects present in the seeds the chance to become active and start reproducing.

The Right Storage Options for Your Cannabis Seeds

You now understand that you must store the seeds away from direct light. We have also outlined the need for relatively low humidity and a refrigerator-level temperature. Different options are available depending on how long you intend to store the seeds.

Short-Term

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.

For short-term storage, place the seeds in a container with desiccant. Seal it, and place it in a cool, dark place.

Medium-Term

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.

Also, you should note that modern fridges have low humidity levels. If the humidity is too low, your seeds will begin using up nutrients.

Long-Term

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 also have the option of placing the seeds in the freezer. Remember, though; you need to germinate them immediately upon removal.

A Note on Insects & Pests

Imagine paying $100+ for seeds, going to the trouble of storing them, only to find that insects ruin them. Unfortunately, all you need is one insect in a container to destroy all of your seeds. The first consideration is to avoid exposure to ultra-low humidity. However, for long-term storage, this is precisely what you are supposed to do!

One option is to spread diatomaceous earth (D.E) where you store them. This is a type of sand that has a fossilized algae base. Crucially, for our purposes, it serves as an excellent natural insecticide. Unfortunately, you shouldn’t use D.E if you plan to store your seeds in a fridge with other food.

Imagine paying $100+ for seeds, going to the trouble of storing them, only to find that insects ruin them.

It would help if you also stored your seeds as high above the ground as possible. This reduces the possibility of a pest like a rodent coming in and feasting on the seeds.

Insects and pests also thrive in dirty storage areas. As a result, you must ensure the storage area remains clean. Otherwise, you won’t just attract pests to your seeds; microbes will form and damage the seeds. Do you want to consume marijuana from contaminated seeds?

Germination

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.

If you have old seeds not stored in ideal conditions, there are still a few ways to germinate them.

  • Remove the hard ridge with a sharp knife.
  • Soak the seeds in carbonated water with germination booster, fulvic acid, or hydrogen peroxide. Use room temperature water, and perform this pre-soak for at least 12 hours in a dark area.
  • Scratch the tough outer shell with sandpaper. Believe it or not, this process could help warmth and moisture get inside. This process is called ‘scarring’ and should happen before you soak the seeds.
  • Make a small cut into the shell as a last-ditch attempt to get it to sprout.

Final Thoughts on Storing and Preserving Cannabis Seeds

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.

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.

When storing cannabis seeds, you must ensure they are not exposed to germination conditions. This means keeping them away from direct light. Also, store in 20-30% humidity (8-10% for long-term storage) and a cool temperature. Keep the environment clean to avoid pests, and consider the tips above for germinating old seeds.

How to Store Cannabis Seeds

Knowing how to properly store your cannabis seeds isn’t rocket science, but to a beginner grower especially, there’s a lot to be aware of. The key factors in maintaining seeds are storage methods, light, temperature, and humidity. If this looks like a minefield, don’t panic!

In this article, we’ll walk you through the main dos and don’ts of storage – not just the hows, but also the whys – and those precious seeds will be good to grow when you’re ready.

Understanding the Key Elements of Seed Storage

To store marijuana seeds, it’s essential to starve them of the conditions they need to develop. Failure to do this can lead to a drop in germination rate, and you could easily find yourself opening a container of useless seeds which are no longer viable.

Consider all the variables involved in plant growth, and if needs be, carry out further research to better understand how these can impact seed storage. Since most plants see winter as the time of dormancy and spring as the time of new growth, the way you store your seeds should try to emulate the critical conditions of winter, which should keep the seeds from germinating.

The Idea Conditions to Store Cannabis Seeds

Temperature

Storing seeds at the correct temperature is vital.

This is because warmer temperature changes tell the seed that winter is over, and along with other cues, begins germination. The temperature you store your seeds at must be kept stable throughout the storage period, so avoid storing in conditions where temperature can fluctuate. A cool place is best.

If you’re storing your seeds long-term in a fridge, be aware that the temperature will undergo a slight change every time you open the door. Store seeds towards the back of the fridge, and if possible, try to use a separate fridge purely for seed storage.

Put them in a suitable, light-proof container, and leave them there until you plan on using them. There are different opinions on the correct temperature but aim for somewhere in the region of 5-8°C, or 41-46°F, as this keeps the seeds cold enough to avoid cracking open. But it’s not cold enough to damage the seeds.

Humidity

Keep humidity levels in check to protect the seeds’ outer shell. If the humidity level begins to rise, the seed can interpret the moisture as a signal to burst into life and start growing. This doesn’t mean you want the storage environment to be as dry as possible. This further damages by dehydrating the seeds. A relative humidity level of 20-30% is best; any higher could effectively spark germination.

Be aware that refrigerator storage does carry some risk of variable humidity and that long-term storage calls for a lower level of humidity around the 10% range. A dry place is the best place.

Light

Outdoors, sunlight is a vital stimulant, and cultivators use artificial lighting inside to help plants grow. Meaning, light is another stimulus to be avoided when safely storing your seeds. Storing seeds in darkness at low temperatures with low humidity is vital for keeping them dormant.

Even the light bulb in your fridge could potentially pose a problem, which is why we recommend stashing them away and leaving them there. If you have a designated fridge for seeds, close that fridge door quickly, and keep it closed until you intend to take the seeds out to plant them. Avoiding too much light exposure is key.

What Should you Store your Seeds in?

The good news is that there are options, most of which are easy to get no matter where you live. There are some caveats to each of these options, which will be explained.

Envelopes

Suppose you’re storing a smaller quantity of seeds over a shorter period (weeks or a couple of months). In that case, an envelope makes an ideal storage solution, as the paper is suitably thick to protect the seeds from light and moisture, keeping them dormant over the short term. The beauty of an envelope is that you can grab a pen and write any relevant details on the pouch to remind you what you’ve stashed away and when. You may want to note the number of seeds, strain details, and date of storage on the outside. When you come to fetch them, you can see exactly what you’ve got in each envelope. If the original packaging meets this criteria, even better.

Toss a desiccant pack in the envelope with the seeds to keep the humidity level stable, or if you’re in a pinch – or if you’re just thrifty – a small handful of rice will do the same job. As long as you don’t use the kind of envelopes with an address window, you can confidently store seeds in an envelope or similar type of pouch in the back of a drawer or cupboard for a shorter time.

Glass Jars

These hold a clear advantage over envelopes in that they’re entirely airtight. We’d recommend using the kind that seal with rubber stoppers rather like a mason jar, than plastic lids, simply because most plastic lids can let in small amounts of moisture over time. Again, a desiccant pack is your friend here to absorb any additional moisture within the jar. Use a paper towel or some cotton balls to keep it separate from the seeds, then pop the stopper in the jar, and wrap or cover it in something opaque to protect the precious contents from light. This important factor will preserve your seeds for over a year and longer if refrigerated.

Desiccant Packs

Those little pouches that you find in the packaging for all manner of items, from electronics to sports shoes, make for an essential ingredient in the seed storage game. Typically containing silica gel, a substance that absorbs moisture, these sachets are your chief ally for limiting mold growth and reducing spoilage inside sealed containers. You can buy desiccant packs online and are cheap to buy in bulk. If your seeds are stored in plastic containers, mylar bags or a plastic bag – these may be essential.

Other Tools to Consider

For those really serious seed collectors, you may want to track and monitor your seeds’ climate. This can be achieved using something relatively cheap like the Govee range of sensors which can be linked to your phone via Bluetooth or your network via Wi-Fi to allow tracking of your seeds’ conditions without having to disrupt them.

Safely Store Cannabis Seeds

Ensure your storage method meets the necessary criteria beforehand, and as long as it’s clean and insect-free, it should stand you in good stead, especially for short-term storage. Resist any temptation to open your seeds to check on them or add more seeds – if you have more seeds to store, use a new container every time, or you run the risk of creating the kind of fluctuations that cause problems for your existing seeds.

While research typically yields differing opinions over the optimal temperature and humidity levels for storing seeds, one thing is clear: consistency is key. Whatever you decide upon, your main objective is to keep that as consistent as possible in the most ideal conditions. It is change that the seed recognises the most. While it’s vital to keep light out of the storage environment and keep temperature and humidity levels low enough to avoid germination – but not so low as to damage the seeds – it’s crucial to avoid fluctuation of any of these variables.

How Long can you Store Cannabis Seeds?

Well, if you follow all of the above it could be a very long time indeed. Marijuana seeds, ideally though, should be germinated sooner rather than later. If kept at room temperature in an airtight container, the answer is around 16 months (although this is debated). However, if they’re vacuum-sealed, and kept in a dark place without fluctuations in temperature, it could be years. The lifespan of a seed depends on you.

Avoiding temperature fluctuations, excess moisture and keeping them in a storage container that meets that criteria means your seed germination should be easy.
