Why Are Your Cannabis Seeds Not Germinating?
Many first-time growers and inexperienced planters often experience this problem when trying to cultivate cannabis seed. They end up languishing and wondering why their effort is not yielding since a cannabis seed has a pretty high germination rate (99%). However, many things might not promote the germination process.
Generally, cannabis seeds are powerful and grow pretty fast. If the seeds do not germinate, there is likely a problem with the germination method. This article will explore many things that can go wrong when trying to cultivate cannabis seeds.
The chances of having a viable seed increase significantly if the genetics is good. This is pretty important as it can avoid wasting energy and effort trying to germinate a bad seed. When you buy good quality seeds from trusted banks, you can breathe a sigh of relief, knowing that your actions will not be wasted.
As a result, it is not a good idea to grow seeds that you stumbled on inside a cannabis bag you got. Such seeds could be infertile and may not germinate. If it eventually germinates, you might not like cannabis. Make sure to buy the right seed from reputable stores and increase the chances of germination.
Direct Soil Germination
This is one of the top reasons your cannabis seed is not germinating. If you do not water the substrate before sowing the seeds and water afterward, there is a high probability that the seeds will not grow. This is not surprising as the seeds could be buried too deep, and adding water after sowing worsens this.
You can obtain good results by germinating the seeds in jiffy pellets, peat plugs, or using kitchen paper and later transplant them to a pot or the soil when the small seedlings come out. Make sure to care for your tender plant at this stage. Limit irrigation, support the right temperature and use Northern lights when growing indoors.
Wrong Temperature and Humidity
The ideal temperature for germinating cannabis seeds is high humidity and high-temperature levels. It is essential for people in tropical countries to provide external support of heat to get the temperature within reasonable and acceptable ranges. This is where heated greenhouses come in. Not only do they provide the right temperature, but they can get the humidity level to the ideal range essential for germinations. A cannabis seed needs 70% relative humidity and an average temperature of about 270C for germination.
If the temperature and relative humidity ranges are lower than the ideal value specified, the growth rate will be slow and unsuccessful. Excessive range, on the other hand, can lead to fungal problems.
Seeds Planted too Deep.
The amount of energy available to a germinating cannabis seed is limited. As a result, if planted too deep, it might not have the required energy to make its way up. A seed planted underground will have no light and is not producing food yet since no photosynthesis. Planting seed too deep creates extra stress for the seedling as migration to the surface becomes an issue.
As a result, you should plant your cannabis seed around 2 to 3 cm down or half inches deep. With this, they have enough room to grow taproots. This might be one of the reasons your cannabis seed didn’t grow.
Using Old or Unsterilized Pots and Soils
A fungus is one of the greatest enemies that might affect the germination of cannabis seed. If you reuse soil and it is not sterilized, there is a high chance of mold and other unhealthy organisms like insects and bacteria. As a result, the seeds may not sprout at all. Even if they grow, these organisms might kill them after a couple of days. For instance, a sprouting seedling might suddenly bend and change color to brown in a process known as damping off. This is common when you supply the seed with too much water when there is poor drainage or the aeration is poor.
Due to this, consider planting seedlings in a sterilized pot as the tendency of containing harmful organisms is low. Also, make sure the containers are clean as it can reduce the tendency of fungus.
Planting lots of Seed in one Pot
Planting a lot of seed in a single container might seem like a good idea due to the ability to save cost. This is like shooting yourself in the leg, as it might lead to a wasted effort. Even if the seeds germinate, they will compete for limited space, nutrients, and water. A cannabis plant needs enough space for its root to travel down without restriction to prevent severe intermodal distance.
Limited space translates to severe competition not only for nutrients but light as well. This is not a good idea if you want to get the best from your cannabis seed. If the seed eventually germinates, they will be weak, which will affect the plants and overall output.
Cannabis Seed left underwater for a long time.
Some growers prefer to soak their cannabis seeds before planting them. This is an essential step to break the dormancy and soften the shell to prepare the seed for planting. With a softshell, the taproot will easily break the body and push its way out of the shell. Typically, the seed will be put inside a glass of water and left until it sinks before the grower plants it. However, this is not as simple as it sounds.
A cannabis seed needs to be continually breathing, and a fully submerged seed will not get the necessary air supply. This might kill the seed if left for long inside the water. Once the seed sinks, take them inside the paper towel as soon as possible.
There are many intricacies involved in germinating a cannabis seed. Getting it wrong with any of the systems might not make the cannabis seed grow. You can arm yourself with these essential tips to ensure that your cannabis plants germinate. Use these tips as a guide when trying to germinate your cannabis seed. Also, if your seed does not germinate, this guide can help you troubleshoot.

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!
Cannabis Seed isn’t Germinating
Cannabis seeds are very easy to germinate, within a few days after being exposed to water, and warmth, most seeds would have germinated. After a week, if your cannabis seed isn’t germinating, there may be problems. There could be a few reasons why your cannabis seed isn’t germinating, in this guide we will discuss why your seed hasn’t germinated, and ways you can get it started. By the end of the guide, you should be able to pop that stubborn seed, and see signs of your plant growing within a week! Good luck!
Germinating Cannabis seeds
Germinating cannabis seeds is relatively easy, as long as you know what you’re doing. Providing the seed with the optimal conditions will improve your chances of a successful germination, so you waste less seeds. This guide is on what to do when a cannabis seed isn’t germinating. The first thing you can do is make sure you have germinated your cannabis seeds correctly. To know what the problem is, it is good to understand possible reasons why a cannabis seed doesn’t germinate.
Why your Cannabis seed isn’t germinating
95% of the time, cannabis seeds will germinate easily, and quickly, just by adding some water, and some warmth. A seed can germinate and show a shoot above ground in just a few days. At the most it should take no longer than a week for a cannabis seed to germinate, and show signs of shoot above the medium, if you do not see a shoot after this long, there may be a problem. There can be a number of reasons why cannabis seed isn’t germinating, let’s explore some of them.
Genetics is half the battle towards a good crop. This can’t be stressed enough, though you can get good plants from random genetics, buying good quality seeds from good seed banks will increase your chances of germination, and a quality end product. Some growers may be tempted to use seeds they found in a bag of cannabis they bought from somewhere. These seeds may not germinate at all, they may be infertile, or if it does grow, it could grow into a hermaphrodite cannabis plant. Improve the chances of your seeds germinating by buying good genetics. You won’t regret it!
Age of the seed
Inside of a cannabis seed there are some stored up nutrients. When a seed gets wet, a small amount of water will make its way inside, and this is a signal for the plant to begin germination. These food stores can become less and less nutritious as time goes on, and if cannabis seeds are not stored correctly, these stores can be used up, without the seed germinating at all. Your seed will need this food store to grow a tap root, and push a shoot above the medium, if it is used up, your seed isn’t viable, and it will not germinate.
The Older a seed is, the harder the outer casing will be. So, if you know your seed is old, you should soak it for a little longer before planting it to soften the shell a little. This will make it easier for the tap root to get out and start to grow.
Incorrect storage methods
If a cannabis seed is stored incorrectly, they will lose viability. To keep cannabis seeds viable for longer, they need to be stored correctly. Incorrect storage is a big factor in germination, and could be the reason why your cannabis seed isn’t germinating. Cool temperature between 5 and 10°c and humidity levels no higher than 25% is a great way to store your cannabis seeds. A dark cool place with very few temperature fluctuations is ideal. A refrigerator is perfect, but do not use refrigerator that you use often. Opening and closing the door will change the environment in the fridge. A stable environment is what a cannabis seed needs. If they have been stored incorrectly, they may not germinate at all. Store your seeds in a light proof container, in the back of the fridge, and your seeds could stay viable for years.
Left underwater for too long
Some growers like to soak their cannabis seeds in water before germinating them. This softens the shell, and prepares the seed for planting. If the shell is soft, the tap root will not have to work so hard to push its way outwards. The seed is placed in a glass of water, and usually, the grower waits until the seed sinks before planting. But this can be a problem. A Cannabis seed needs air to breath, and once the seed has fully submerged it cannot get air any more. This can kill a seed, as it can drown. Do not leave your seeds fully submerged for more than a couple of hours. Once they sink move them into paper towels or your chosen medium.
Planted too deep
Don’t plant seeds too deep! A seedling will only have a certain amount of energy it can use. To make its food, it needs light. Whilst a seed is underground, it will get no light, and without it, the plant cannot photosynthesize and make the food it needs to grow. If you plant your seed too deep, it will not have the energy it needs to break through the surface. Plant cannabis seeds about 1/2″ deep (2-3 cm) and this will give them plenty of room to grow a tap root, and then shoot above the surface. Planting your seed to deep may be the reason why your cannabis seed isn’t germinating
Too much nutrients in the medium
Sometimes, cannabis seed will germinate beneath the medium, and of course, you will not see it. The tap root will grow and come into contact with the medium. If the medium has a lot of food in it, it can severely shock your seedling and it can kill it. When you are germinating cannabis seeds, be light on the nutrients, and if you’re planting into soil, make sure you’re using a potting mix. A potting mix will have less nutrients in it than normal soils, and this can be better for young plant to grow into, before moving them into strong mediums.
What to do when a Cannabis seed isn’t germinating
After you have tried to germinate your cannabis seed, but had no success, you shouldn’t just give up there. There are ways you can still get your cannabis seed to germinate, it may just take a little more work. The main objective is to soften the shell, and provide the tap root with as much help as possible it is emerging from the seed. Sometimes all it takes is a slight break in the shell, and the seed can germinate.
Soak the seed with H²O²
If you’re seeds are old, you may want to do this on the initial soaking, before you try germinate your seeds, but it is also a great method to try and crack stubborn seeds. H²O² will make the water a little more reactive, but only use a few drops in a glass. Hydrogen Peroxide will help soften the shell, making it easier for water to get inside the shell, and for the tap root to emerge.
Add some microbes to the seed
Roots love microbes! If your cannabis seed isn’t germinating, try rolling it in a rooting power and plant it again. When exposed to moisture these powders will begin to grow colonies of friendly bacteria that works in conjunction with the root zone. These can help soften the shell, and produce some nutrients for when the tap root emerges from the seed. If your cannabis seed isn’t germinating, some beneficial bacteria can be very helpful.
Using 2.5ml per cup of water of fulvic acid can also help weaken the shell of your seed and help it germinate. Fulvic acid is an organic acid, that is found in soils, and comes from the decomposition of organic matter. This will help break down the outer shell of your seed, as the organic molecules break down the casing.
Carbonate water has CO°2 dissolved into it. This takes it from being still water to being fizzy. The bubbles in carbonated drinks are formed on nucleation sites. This is where the CO²2 can latch onto a place, and turn into a bubble. The bubbles then form and float up through the water. This makes the water more reactive, and can help soften the shell of your seed if it isn’t germinating.
If none of the above techniques have worked for you, there are some last resorts you can turn to if your cannabis seed isn’t germinating. These are harsh, but they can work, you just have to be gentle. The whole idea of these techniques is to either soften or crack the shell, so water can get into the seed, and the tap root can get out. This can be difficult if the seed is old, or has been stored incorrectly, so we have to give it a helping hand sometimes.
Take some sandpaper, of a very fine grain, and gently scuff at the outer shell of your seed. Now be careful, you’re not trying to removing the whole layer of the seed. Just scuff the surface in a few places, and begin the germination method again. This will weaken areas of the seed, which can now be softened and penetrated by the water. But sometimes this still isn’t enough. You can also use a nail file to scuff the edge of your seed, just make sure its fine grain as you do not want to remove big pieces of shell.
Cracking the shell
The very last case scenario, and your last resort is to actually crack the seed manually. This can be done by holding the seed between your finger and thumb, and using your other hand to pick of a bit of the casing with your thumb nail. By putting a small crack in the seed, you can be sure water will get in, and the germination process should begin. Do not soak the seed for too long, and it may be better to go straight into the medium after you have cracked the seed. Too much water can drown it, and you don’t want to kill your seed after going through all this trouble to germinate it.
Final thoughts on Cannabis seeds that won’t germinate
If your cannabis seed isn’t germinating, then you should just be a little more patient, most of the time, they will pop without any extra help, they just need a couple more days. If you have waited for longer than a week, than you should start using these methods. Buy your seeds from a seed bank with a good reputation, and your seed should germinate first time every time, as long as you germinate them correctly. Thanks for reading!
