What to do if your cannabis seeds do not germinate: 3 practical tips
Cannabis seeds are real living organisms and as such are susceptible to many environmental factors, such as light, humidity and temperature. If you’re wondering what to do if the seeds don’t germinate, maybe you need to freshen up on what European law says about it.
The sale and possession of seeds are legal in our country, as they do not contain any trace of THC. However, if the weed seeds germinate, they would give birth to a plant capable of producing inflorescences with a high rate of tetrahydrocannabinol, turning your culture into an administrative offence.
The marijuana seeds that you can buy online in shops like Sensory Seeds are purely collector’s items and can be used for purposes that do not involve germination, such as collecting. However, in other countries, the cultivation of hemp seeds is legal for personal use, such as in some cities in Spain.

Here are 3 practical tips to protect the health of the seeds to be germinated (where cannabis home cultivation is allowed).
1) Which seeds do not germinate? Here is how you can recognise them before it is too late
There are many reasons why marijuana seeds do not germinate, and it is not always easy to recognise the cause. However, there are signs that you may be able to identify those specimens that are likely to cause problems. Improper storage is one of them and can be the cause of your seeds not germinating because they are already dead.
It can happen if you have bought your cannabis seeds from unreliable sites that sell off old items as discounted products. Seeds that do not germinate may have changed colour and become significantly darker or have a white patina on the rounded end; moreover, if you open the seed, you will notice that the embryo has become soft.
For this reason, we recommend that you always check the health of the seeds as soon as they come into your hands, mainly if you are used to buying your weed seeds online. In this case, you should only turn to reliable shops like Sensory Seeds, which guarantee the health of the products in your shop window.
2) Do you want to try to germinate an old seed? Here’s what you can do
If you have an old marijuana seed in your hands or you have tried to plant it, and nothing at all has happened, you can try to make a desperate attempt to resolve the situation. There are 4 ways you could proceed, and they are as follows:
- Soak the seeds with enhanced water
- Seed shell rubbing (scarification)
- Cut the joint that closes the seed
- Dissect the seed
The first attempt to do among these is undoubtedly to soak the unsprouted cannabis seeds in a container with sparkling water or, better still, enriched with fulvic acid or growing booster. Keep the solution at a temperature of 20°-22° and away from light for 12 hours: in this way you may be able to get moisture into the dehydrated shell and give the embryo the starting input, but be careful not to exceed 24 hours of soaking.
If after this attempt the seed does not show signs of life, you can move on to scarifying the shell, i.e. its abrasion to create grooves that facilitate the passage of moisture to the embryo. Insert sandpaper into a container, tape it up and put the cannabis seeds in it: after closing the lid, shake the container for a minute or two and then try again to soak the seeds in water for a few hours.
Still nothing? Take a knife with a smooth, sharp blade and slide it along the kerb of the two halves of the seed shell until it is removed: a very thick shell can make it difficult to open the seed to get the rootlet out. If the first 3 attempts are unsuccessful, dry the seed, cut the shell with a sterile scalpel along the groove under the shell and try to germinate it.
If you haven’t managed to win the battle in this way either, you will, unfortunately, have to feed the seeds to your budgies…
3) All you have to do not cause the cannabis seeds to fail to germinate yourself
There are many causes for a hemp seed not to germinate, including fungal infection. This type of mould can attack your seeds in the following cases:
- Poor quality soil
- Excess humidity
- Too much watering
- PH inappropriate
- Poor ventilation
- Temperatures too low
The guidelines for storing seeds before planting are stringent:
- The temperature of 6°- 8° C
- Humidity between 20% and 30%
- Keeping in the dark
- Avoid oxygenation
- Maintain the stability of the previous parameters
If you clumsily follow these directions, you might run into the problem we’ve been talking about. Besides, if the extreme methods of achieving germination have not been successful, you may find that the embryo is infected with liquid-looking, yellowish fungi.
Other problems can arise from using chlorine-laden tap water (it is best to let it evaporate 24 hours before use) or from breaking the semen shell due to pressure, which you should always be very careful of.
Final considerations on unsprouted marijuana seeds
Poor germination is not always your fault, as there may be external factors that make it difficult or sometimes impossible. In some cases, the soil used may have been a fungus carrier or its type was not the right one; other times the fault is due to a malfunctioning or poorly calibrated conductivity meter.
Falling into a failure to germinate is sometimes almost inevitable: in some unlikely circumstances, you may have done nothing wrong, but your seeds will still not germinate.
To make a summary, cannabis seeds that do not germinate may be defective due to external causes or inadequate storage. If the seeds do not germinate immediately, you can try using the techniques we have mentioned in this article and hope that they work.

Why Won’t My Cannabis Seeds Germinate?
If you’re growing cannabis from seed, life begins at germination. But what happens if your seeds won’t germinate? Are you just doing it wrong?
It’s possible, but other factors contribute to the successful germination of seeds. Let’s look at what to do right, what can go wrong, and how to minimise the risk of germination failure.

What is Cannabis Seed Germination?
Germination is when the outer shell of a seed cracks open, and the first sprout pops its tired head out to see daylight for the first time. From there, your seed is awake, alive, and ready to grow into the superb cannabis plant it dreamed of becoming. The first initial sprout to break the surface of the seed is known as the taproot. That’s the root from which all other roots made by your plant will sprout. Once the shell breaks open and the taproot emerges, you can plant it in soil. With time and the right conditions, you’re well on your way to growing a healthy marijuana plant. If you’re wondering why your cannabis seeds won’t germinate, there are some important things to know.
Cannabis seeds need three things to germinate:
Each is a vital cog in the germination process, and if just one is missing – or inadequate – you’re looking at a bust. Therefore, it’s crucial to know how to germinate your seeds correctly.
Three Ways to Germinate Cannabis Seeds
As sure as there’s more than one way to skin a cat, there’s more than one way to germinate a weed seed. Which way is your choice, and how you choose is entirely up to you. Some methods are more straightforward, and some are slightly more scientific. The main thing, however, is simply knowing what’s involved in your preferred seed germination method and following the instructions to the letter. Doing this allows you to rule individual errors out of the equation if things go wrong. Here’s a quick and easy guide to three popular methods of germinating cannabis seeds.
The Wet Paper Towel Method
Without a doubt, the simplest method, and probably the most common method among home growers, the paper towel method, has been around forever.
All you need is four paper towels or kitchen paper, two plates, and some distilled water. Begin by dampening the paper towels with distilled water. Place two of your damp paper towels on a plate, then grab a utensil like a set of tweezers or tongs, and use them to place the seeds on the paper towels. Carefully place the other two damp towels on top of your seeds, and cover with the other plate.
Cannabis for Beginners
Keep your newly-crafted ensemble in a spot where the temperature is between 20 and 30°C, checking on them daily. After just a couple of days, if you see the taproots have emerged, congratulations! Your seeds have popped and are ready for the next stage.
The Glass of Water Method
It’s said that this method is less effective than the wet paper towel trick, but some people prefer to drop their seeds in a glass of room-temperature water and wait 3-5 days until the seeds pop and the taproots emerge. It’s probably even more straightforward than the paper towel method. Whatever floats your….seeds….
The problem with this method is that it seems directly counter-intuitive to the philosophy of seed germination 101 – too much water will drown your seed. Yet somehow, people have success with it.
The Soil Method
You want to limit the handling of your seeds as much as possible, so what better way than to drop them straight into the soil and let them germinate there? Put some soil in a small pot and water it, then make a small hole about 15mm deep in the centre, and carefully place the seed (one seed per pot) in the hole. Cover with a light dusting of soil, then mist with water. This method takes longer, so you’re waiting between four and ten days for the seed to germinate. The beauty of this method is that the taproot emerges into the soil, meaning no further handling, and the roots can get to work developing in the substrate.
My Cannabis Seeds Won’t Germinate
It’s not uncommon, but as long you’ve followed our germination guidelines correctly, you know at least it wasn’t your fault. So what went wrong?
Here’s a list of common reasons why your seeds may not have sprouted:
Poor Quality Seeds
Where did you acquire your seeds? There are plenty of disreputable sources for cannabis seeds out there, be they online retailers, back-alley head shops – or even just a jiffy bag of random undefined seeds from a friend. The genetics aren’t assured, quality control is non-existent, and as for after-sales care? Forget about it.
To give yourself the best chance of success, only buy your cannabis seeds from a quality seed bank like Seedsman.com. The variety and quality of cannabis seeds are second to none, and they come with the peace of mind of knowing your seeds will have a much higher germination success rate. Better yet, you get the added value of knowing those seeds will grow into cannabis plants of the highest quality, with bountiful yields. You don’t have to break the bank to purchase top-grade marijuana seeds. From competitive prices on the latest strains to regular special offers, Seedsman.com offers premium cannabis seeds to suit any budget.
Improperly Stored Seeds
Not everyone realises that seeds have to be stored correctly to remain viable. If you’ve unfortunately got your hands on some old seeds, there’s a high chance they might not have been stored properly. If your seeds have been sitting in a bag on a window ledge, chances are the heat has sucked any chance of germination out of them completely. Treat your seeds like you would treat food. Whether you store in a cool, dry place or in a refrigerator in the correct container, you need to preserve them correctly to ensure they don’t spoil.
Over-Handling or Incorrect Handling
Treat your seeds with the utmost care at every step. If you over-handle them, use bare or dirty hands or use the incorrect tools to lift and lay your seeds, there’s a good chance you’ll damage their viability. Bare hands are harbours of all manner of bacteria, so it’s a good idea to use medical-grade gloves if you’re picking them up. Failing that, always wash your hands before and after handling cannabis seeds – but be careful what you use as soap!
The less you handle cannabis seeds, the lower the risk of damage. Sure, cannabis seeds seem hardy enough with that tough outer shell, but it would surprise you how easily they can be damaged. The same rule applies if using tools to lift and place seeds – tweezers and so on should be cleaned before and after use. Resist temptation to apply too much of a squeeze, as that can damage the seed shell.
Incorrect Planting Techniques
If you’re planting your seeds straight into the soil, place the seed carefully and gently into that 15mm hole mentioned earlier. Cover lightly with soil, and do not be tempted to push the seed further down into the soil. Don’t compress a large amount of soil over the top of the seed, either. This will do more harm than good because your seed won’t have the oxygen it needs. Likewise, excess moisture can scupper the chance of germination.
Everything from handling tools to pots and soil has to be spotlessly clean and sterile. Otherwise, you limit your seed’s chances of making its big breakthrough. Ensure you sterilise your pots; otherwise, there’s a good chance there will be residual mould and pathogens. Likewise, only ever use clean, new soil to accept your seeds.
Incorrect Water/Moisture Levels
Too much moisture in your soil and your seeds will suffer from a lack of oxygen. If that’s not bad enough, excess water will encourage fungal growth.
Too little moisture is just as bad – remember, moisture is one of the three critical components in the seed germination process. If using the paper towel method, ensure those towels are damp and not soaked. When potting in soil, make sure to mist the soil with a spray bottle. Don’t pour copious amounts into the soil, thinking the more, the merrier. If you’re overwatering the soil at this stage, neither you nor your seeds will be particularly merry.
You Germinated for Too Long
It can happen – if you take your eye off the ball, your seeds will have germinated, and that taproot has been exposed to air and light for too long before being planted in a safe growing medium. Don’t keep them out in the open beyond 2cm. If you do, handling and transporting the sprouted seed increases the risk of damage. Get them in soil or your preferred substrate as soon as possible.
Seeds germinate best when the temperature is between 20 and 25C. High temperatures increase the risk of drying out the soil. Any lower exposes the seed to conditions that could effectively stunt development or halt germination altogether. For this reason, we recommend carrying out germination indoors, where you can control the temperature.
After successful germination, allow your cannabis seedlings to develop indoors in pots. Wait until the outdoor temperature is high enough that your young plant will thrive (if you’re planning to grow your plants outdoors, of course).
Too Much Light
Cannabis plants love light – well, photoperiod ones, certainly. But seeds? Not so much. Light is not essential to seed germination; in fact, it’s not conducive to seed germination. Keep your seeds away from light as much as possible if you want them to have a chance at popping. Carry out germination away from windows and any other light sources, or you’ll hinder the likelihood of success.
The ‘Wrong’ Water
Avoid using tap water in the germination process. Tap water contains chlorine, fluoride and other additives that can harm seeds and potentially stop them from sprouting. Instead, use distilled water. Bottled water is fine.
They Can’t all be Winners
As you can see, there are plenty of reasons why your seeds may not germinate successfully, and it’s a lot to consider. Keep this guide handy if you’re new to growing cannabis from seed, and follow the steps outlined above until you’re experienced enough to go it alone.
Always remember that, even if you do everything by the book, some seeds just won’t germinate. Frustrating though that is, sometimes it’s just bad luck. But by taking control of all the factors mentioned above, you significantly increase your chances of successfully germinating your cannabis seeds every time. Over many grows, an 100% germination success rate is unheard of. By obtaining good quality cannabis seeds from a reputable source like Seedsman.com, and following the guidelines, you can get pretty close. Good luck!

Cannabis seeds do not germinate, what now?
Weed seeds don’t germinate: It’s every grower’s nightmare: You’ve ordered some nice seeds and they don’t germinate. Or even worse, you’ve had them for a long time, stored in the best conditions but still nothing happens.
How can this be?
Cannabis seeds do not germinate for various reasons. We give you the 10 most common explanations for non-germination:
- Temperature too low. Young cannabis plants do not grow in too cold an environment. If the seeds germinate, the development of the plants will not be regular. The seedlings are also susceptible to diseases. A seed that has not yet germinated can even die as a result of too low a temperature. You can avoid too low a temperature by germinating indoors. Once germinated and with roots, you can move the young plant outside. Be careful not to do this too early in the year when it is still too cold.
- Too high a temperature. If a cannabis seed gets too warm, it can be damaged. The soil in which you have planted the seed can also dry out if the temperature is too high.
- Earth too wet. Water plays an important role in the germination of a cannabis seed. If your cannabis seed does not germinate then this could be the result of giving it too much water! Generally speaking, water will activate a hormone in the seed that triggers germination. Too much water prevents air and oxygen from reaching the seed. And a too wet soil is also the perfect breeding ground for mould related plant diseases.
- Soil that is too dry. Since seeds need water to germinate, a soil that is too dry will also be a reason if you notice that your cannabis seeds are not germinating. It is essential that the soil is kept moist. Dried out soil doesn’t give the seed the moisture and nutrients it needs.
- The seed is planted too deep. A rule of thumb for planting (cannabis) seeds is: twice the size of the seed is the depth at which it should be planted. The cannabis seed has a limited amount of nutrients that are used up when the seedling reaches the surface. So if the seed is buried too deep, it will never rise above the soil. Temperature also plays a role here: the deeper, the cooler. And cannabis seeds do not like the cold!
- The seed is not planted deep enough. If the seed is not planted deep enough, it will probably dry out.
- The soil has been compacted too much. If the soil is too compact, the much-needed oxygen cannot reach the seed. Also, the drainage of compacted soil is not good.
- The soil is too airy. If the soil is too airy, there may be too much air circulation around the seed. It will then dry out and dried out cannabis seeds will not germinate.
- The soil has a fungus. Fungi develop in the soil when there is too much water and not enough air circulation. If mould grows in the soil, then the seed may germinate, but the roots cannot get a grip. Eventually, the seed will still die.
- A dead seed. A dead seed will not germinate, of course. Even if all conditions are perfect. To make sure your seeds don’t get damaged or die you have to store them in the right way. If you do not do this then the weed seed will slowly die.
These are the 10 most common reasons why a cannabis seed does not germinate. Fortunately, the solutions are fairly simple to implement. What are your experiences with non-germinating cannabis seeds?

What is the best way to germinate cannabis seeds?
1. Put the cannabis seeds in water for 24 hours, so that the skin softens and the seed can germinate more easily.
2. pack a coffee filter and a grip bag as shown below
3. wet the coffee filter with spa blue so that the value of the water is good, or measure the ph value.
4. put the seeds in and then put the coffee filter in the grip bag as shown below.
5 Hang the bag with a clothes peg or tape (make sure it is between 22 and 27 degrees).
After 1 or 2 days you will see the seed appear with the root downwards as soon as the root is 1.5 cm, you can start planting the seed.
