how long can you keep cannabis seeds

There is plenty of debate surrounding how long do marijuana seeds last before they go bad. Some people say that they can last for years if they are kept in the correct conditions, while others disagree and state that they can only be used within 6 months to 1 year after packing. So the question is, how long do marijuana seeds last?

Will Cracked Marijuana Seeds Still Germinate?

As we mentioned before, marijuana seeds can be made to last very long if they are refrigerated. Without any interference, marijuana seeds can last a few months before they go bad, even up to a year if they are kept in a cool, dry and dark place, but if they are refrigerated, marijuana seeds can last up to a decade.

How Long Do Marijuana Seeds Last Before They Go Bad?

Unfortunately, the answer to will a cracked seed still germinate is No. It cannot germinate as the valuable internal part of the seed that contains the genetic information of the plant is exposed, then the seed will no longer germinate. Great care must be taken to ensure the seeds are not damaged or crushed, including putting them in vials stuffed with cotton wool to ensure they don’t rattle around and harm each other.

When working from the start you’ll first need to pollinate the flowers on a female cannabis plant and then harvest the seeds once it’s fully matured. Once you have your seeds you’ll need to dry them out before they can be stored or even germinated – they should be ready to harvest once they’ve gone a dark brown color or start showing dark stripes. Most people opt to dry their seeds by simply drying the flowers and harvesting the seeds once they’ve dried out – it makes them much easier to remove from the flowers.

Humidity is another incredibly important factor that can determine the success rate of your seeds. Relative humidity is essentially what causes seeds to germinate, so they’re quite delicate at this stage and you don’t want them accidentally germinating; keep relative humidity low in their container.

How Long do Marijuana Seeds Last in Storage?

There are many different factors that come into play when it comes to cannabis seed lifespan, and the most important is conservation. If you’ve obtained your seeds from a seed bank and they come in their own packaging, when it comes to storage you can simply leave them in their packaging in a dark, dry spot; seed banks usually recommend planting within the year.

Once you have your seeds you’re going to want to store them correctly if you plan on using them down the line. In fact, when stored under perfect conditions, you can germinate 5 year old cannabis seeds successfully. Some astonishing cases have been reported of seeds lasting up to 10 years when stored optimally, although the germination times may vary wildly, taking much longer than a fresh seed. For homegrowers, storing and maintaining seeds is quite important, and even more so for seed banks; a badly stored seed may not germinate, and if it does it may not grow properly. There are various parameters you’ll need to follow in order to store seeds long-term.

Seed Storage: Temperature

Cannabis seeds can germinate with a RH of 40-60%, and humidity higher than that can actually drown them and kill them. However, humidity ranging from 9 – 20% may also cause a myriad of issues such as insects, fungi, and even seed sweating due to excessive heat. The ideal humidity range in which to store your seeds is between 20 to 30% RH.

If the humidity level falls below 20%, the seed may heat up and sweat, develop fungi on the outside as well as the inside. At the lowest humidity level of 10% or less, the seeds can attract insects or pests.

Healthy seeds should also be firm to the touch and have a glossy and wax-like look to the shell. If you roll the seed between your thumb and index finger and it feels firm, then it should be a good seed to plant and should store well in the right conditions.

If you are going to go to the trouble of storing cannabis seed long-term, then you want to make sure you are storing only good seeds. After all, what would be the point in storing bad seeds? Most of the time you can tell a good quality of a cannabis seed by the way it looks.

Effects Of Humidity On Cannabis Seeds

It can be a glass container with a sealing lid. Ziplock baggies are alright to store seeds in if you do your best to remove as much air as possible.

If you are a regular weed user and live in a US state where it is legal, chances are you have already tried your hand at growing your weed. If you haven’t tried it yet, well, there is a lot to learn.

How you store your cannabis seeds works in much the same way as when you store your cannabis. Humidity can play a huge factor in how well your seeds stay preserved and for how long. In fact, humidity plays a major role in the entire lifecycle of the cannabis plant, from seed to storage of the finished flower, and ending in consumption. We even have a guide to rehydrate your cannabis if you fail to keep it moist enough and even have information on freezing your cannabis, which can cause mold issues quickly. But I digress.

How Can I Tell If Cannabis Seeds Are Good?

Growing cannabis is tricky even for experienced growers. It all starts with the cannabis seed. If the seed you plant is no good, then you won’t get a plant at all. If you plant a seed of poor quality, then your plant will likely be of poor quality too.

Some people that grow their cannabis prefer to purchase their seed online, while other growers prefer to save and store seeds from their plants. How cannabis seeds are stored for later use is of the utmost importance.
