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°
- 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 Didn’t my Seeds Germinate?
Why didn’t my seeds germinate? This is a question often asked by novice and experienced growers alike. Some people think that it’s because they bought old seeds or badly made seeds, but it’s generally because the germination process isn’t done properly. Cannabis seeds have a 99% germination chance, even after being in a box for up to 5 years.
Cannabis seeds are life matter, and if germination isn’t done correctly then the seeds are worthless. Cannabis plants are generally quite sturdy and they grow quite fast, but they’re extremely fragile before they begin their growth spurt. You need to germinate in humid places with a decent temperature, and make sure that the seeds have enough humidity for the 2-10 days it can take for them to germinate. Just because it hasn’t shown any roots in four days doesn’t mean that the seed isn’t going to open, you just have to wait and have some patience.
One of the most common errors is just leaving them in some damp kitchen paper on a plate, as they’ll dry up before they can root. You need to make sure that the paper isn’t dry, if it’s dry you’ll need to give them a bit more water, some people give them too much water in case they dry out etc. These practices are what cause seeds to dry out or to drown in too much water; it’s not the seed’s fault, but generally the grower’s.
Another big mistake is germinating in a glass of water. The issue with this method is many people don’t take into account the water temperature. If the water’s too cold then the seeds will sit there for days until they eventually rot due to the low temperature in the water. This method’s okay for warm summer months when there’s a decent temperature and the water doesn’t get too cold. This still isn’t the seed’s fault.
One of the biggest mistakes is germinating straight in a jiffy or soil. The issue here is that the seeds will most likely take much more than 48h to germinate, and by then the upper layers of soil will have dried out, and if it doesn’t die off due to that then it will probably die if you try and water it to keep humidity up; in these cases, the seed tends to come to the surface or they can sink even further into the soil. Once again, this is the grower’s fault.
The only way to be sure that your plants are going to get a chance to grow is to germinate them before putting them in the desired medium. The only way to make sure that they germinate is to make sure that the temperature never goes below 20º and that the paper doesn’t dry. How? By using a simple plastic kitchen container. If you germinate your seeds in a plastic container with some damp kitchen paper and you keep it closed, the water from the paper won’t evaporate and dry out. Even if it takes 10 days it will still germinate. Once the seeds have opened, you’ll need to place them in a properly watered pot because you won’t be able to water again until the seedling pops through the surface, although this should only take one day indoors and maybe 2 outdoors. With this system you can germinate hundreds of seeds in a small Tupperware container. If it’s summer and it’s warm, you can just stick them anywhere out of direct light. If it’s the winter and it’s colder you can place the container on top of your TV or internet box to give it that extra bit of heat. If it’s going to be somewhere where light can get to it, cover the box in tin foil.
So, now you know the best way to germinate your seeds. You might have been doing it one of the “wrong” ways and you’ve been lucky so far, but the only way you can germinate and blame the seeds if it doesn’t work is if you use the correct method we mentioned last. Happy growing!
Reasons Cannabis Seeds don’t Sprout
Top Reasons Your Seeds Aren’t Sprouting – And What You Can Do About It
Seeds are designed to sprout, but that doesn’t mean it’s easy. Some seeds sprout just about anywhere, whereas may need very specific conditions before they will crack. When it comes to marijuana seeds, sprouting should be easy, but there are times when the germination rate just isn’t what it should be. When this happens, it’s crucial to look at every part of the setup to determine what went wrong and what can be done to get the seeds to sprout.
Diseases or Mold Killing the Seeds Before They Get Started
Seeds can suffer from diseases and mold just like the plant can once it starts growing. Diseases can kill the seed before it gets the chance to start growing, and mold can cause the seed to die during the germination process. Fungi can also be an issue, as it can cover the seeds and prevent them from being able to sprout. Once diseases, mold, or fungi start to grow, there isn’t much that can be done to save the seeds.
What to Do About It:
Seeds can be soaked in diluted hydrogen peroxide for a few hours before planting. This kills any diseases that could be growing outside the seed so they have the best chance to grow. Watering should be done only as needed to prevent the growth of mold and fungi. The humidity in the room should also be carefully monitored to prevent the growth of mold and fungi and growers should ensure they have good ventilation if they are growing weed from seeds indoors.
Bugs or Other Pests Eating the Seeds or Seedlings
When growing outdoors, it’s easy for pests to devour the seeds. Bugs like to eat the seeds, and birds will often look through the garden and pick out any seeds they can find. Birds are often one of the biggest pests when planting seeds, even though they will be beneficial once the seeds have sprouted by eating caterpillars and bugs that might like to eat your sour deisel seeds or gelato seeds marijuana plant. Birds can destroy an entire crop of marijuana before it even gets started because they will search the area carefully and eat all of them once they know the seeds are there.
What to Do About It
The best option to protect seeds from pests is likely to germinate the seeds indoors. Once the seedlings are a couple of inches tall and they have their first set of true leaves, they can be transplanted in the garden and the birds will leave them alone other than to check and see if there are any bugs on the plants that they can eat. Another option is to use row covers. These can be inexpensively made and will cover the seeds completely until they start to grow. There are plenty of options for keeping birds away from the garden to protect the seeds, depending on what’s already on hand and what is more effective.
Seeds Aren’t High Quality
When seeds are low quality, they’re not going to have a high germination rate. Very few of the seeds are going to sprout and those that do may grow a plant that dies quickly or that suffers from issues while it’s growing, leading to a reduced crop. Buy cannabis seeds, purchased from a reputable seed bank, are designed to have higher germination rates and lead to much healthier plants. They have been tested for higher germination rates, so growers have one less thing to worry about when they’re starting the seeds.
What to Do About It
There likely isn’t much that can be done about low-quality seeds to get them to sprout. It may be possible to soak them in water to soften the shell so they will sprout, but the resulting plant might not be healthy either. Even with that trick, it can be difficult to get low-quality seeds to sprout at all. Instead, it’s best to always purchase high-quality
cbd seeds or thc seeds from a reliable seed bank to ensure the germination rate is as high as possible.
Seeds are Too Old
Seeds should be planted soon after they’re purchased, but many people will order seeds early and wait to plant them. Depending on how long they wait, the seeds will likely be fine. However, seeds will become less likely to grow if they are stored for years before being planted. If you find old feminized weed seeds or other random unlabelled pot seeds in an old cupboard that have been stored for a significant amount of time, the germination rate simply isn’t going to be what it would be if the seeds were planted earlier. High-quality seeds can be stored longer, but still may not sprout.
What to Do About It
Seeds should ideally be planted within a year or two of purchase to ensure the best germination rate. The length of time before a seed is no longer viable can vary, but most seeds will still have at least a decent germination rate if they are stored properly and used within two to three years. The germination rate will decrease further with time. Proper storage means the seeds are kept in a cool, dark place and away from moisture until they will be planted.
Too Much or Too Little Water During Germination
Water is necessary for seeds to sprout, but too little or too much can make a huge difference in the chances of success. Too little water means the shell will be too hard, so the seedlings won’t be able to push their way out. Too much water for seeds started in soil can lead to the growth of mold. Seeds can be started in water to help them sprout faster, but once they begin to sprout, they should be planted in soil to prevent issues.
What to Do About It
Water only when needed. If the soil starts to feel dry, go ahead and water it to ensure there is water for the seeds. Never let the soil dry out completely before watering it again. If the soil still feels moist, there is enough water for the seeds, so wait another day or two to water. Keep a close eye on this during the summer months especially to ensure the soil doesn’t completely dry out during the hottest days.
Seeds Are Getting Too Much Light
Marijuana Seeds should be not just be dropped in the soil and covered with just a light layer of soil on top of them. This not only welcomes seed-hungry pests like birds into yoru garden, but also doesn’t give you much control over the consistency of water and light that they are provided. You wan’t to mimic the conditions that nature provides for idea seed growth: moisture, warmth, and darkness.
What to Do About It
Follow our i49 germination guide and sprout yoru seeds in a damp paper tower. This setup should be kept in a awarm and dark place like a cupboard inside your laundry room or in a box on top of your fridge. If possible some ventilation is helpful rather than a tightly enclosed space, and it is also a good idea to rinse yoru seeds periodically to prevent the development of mold. As soon as you see a taproot emerg, you can remove from the paper towel and transplant to a small amount of growth medium.
The Weather Isn’t Right for the Seeds
When your autoflower weed seeds are planted directly in the soil outdoors, the weather can have a huge impact on reducing the germination rate. If the seeds are planted too early, it may be too cold for them to sprout. If the seeds are planted too late, it could be too hot. Marijuana seeds prefer a warm temperature to sprout and may not start growing if it’s below 60 degrees or above 80 degrees Fahrenheit. Some seeds may start to sprout despite the temperatures, but the germination rate will likely be far below what is expected if it is too hot or too cold for the seeds.
What to Do About It
Always germinate your i49 seeds using our recommended germination methood. This will help give the seeds the best chance to grow. Indoors, the temperature can be more carefully controlled and once the seedlings are large enough and the temperature outside is warm enough, the plants can be transplanted to the outdoor garden.
The Bottom Line
If you’re planning on growing marijuana in the USA, use the tips here to ensure your seeds are more likely to sprout and that you’ll have a higher germination rate. The proper preparation can make a huge difference in how successful you’ll be and can help you cut down on many of the potential problems and frustrations that could lead to seeds failing to sprout.
