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.

Why Won’t My Marijuana Seeds Germinate
So, you have tried germinating your marijuana seeds, unsuccessfully. You might have tried using water, soil, peat, paper towel, or one of several other methods out there, but your seeds still did germinate and grow into a huge kush plant as you hoped. What the heck is going on here? (we recommend ILGM for quality seeds)
Well, there are various reasons why your marijuana seed won’t germinate. Marijuana seeds need pretty specific care and conditions to germinate properly. There could be a problem with too little or too much moisture, the wrong temperature, the weed seed could just be a dud, or there might be another problem too.
Let’s take a closer look at this issue of your weed seeds not germinating. Why won’t my marijuana seeds germinate?
Why Seed Germination Is Essential
Remember guys, all seeds need to be germinated, not just weed seeds. Of course, in nature, this often happens on its own, but if you want to grow your own marijuana plants, you will to germinate them manually. Seed germination is the act of bringing the seed to life.
By supplying it with some moisture and the right conditions, you are causing the interior of the seed to eat through its food, use up that glucose, crack through the shell, and become a little plant sprout.
Just think of it like the sprout being the yolk of the egg, which will grow into a chick, when it eats the egg white or food, which in the case of a weed seed, is the glucose stored inside of it.
A weed seed is not all that much different from a chicken egg waiting to hatch.
Why Won’t My Weed Seeds Germinate? (Using Paper Towel, Peat, or Water As The Medium)
There are in fact several reasons why your weed seeds might not be germinating. Some of these issues are caused by the people doing the germinating, and some simply cannot be helped.
Why are my weed seeds not germinating when I am using paper towel, peat, or water as the germination medium?
1. The Seeds Are Dead Ducks
The first reason why your weed seeds may not be germinating is simply because they are bad seeds. When you get weed with seeds in it, or you purchase seeds, they should look a certain way.
Generally speaking, a healthy marijuana seed is going to be a moderate to dark green in color, and should be fairly round.
If you have a weed seed that is really flat and/or light green or super pale in color, it probably won’t ever germinate. Sometimes seeds are just no good. It happens and there is nothing you can do about this.
However, on the other hand, your seeds might have been good at one point, but were then improperly stored.
Weed seeds need to be kept in a cool and dark environment until it is time for germination. If the weed seeds are not properly stored, they will degrade, die, and they will not germinate
2. Not Enough or Too Much Moisture
Another reason why your marijuana seeds might not be germinating is due to issues with moisture. For one, a lot of people end up drowning their weed seeds outright.
Yes, some people germinate their weed seeds in nothing else but water, but this tends to not have the best success rate, and it is because the seeds end up drowning.
This can also happen if you use soil, paper towel, or peat for germination. It’s not too difficult to drown them, so spritz them with enough water to be moist, but there should not be any dripping going on. Too much water can actually rot your seed outright.
On the other hand, if the weed seeds are too dry, and your germination medium is too dry, the seeds just won’t get enough water to germinate.
Water is an essential part of marijuana seed germination, and without it, nothing is going to happen.
3. Too Much Light
Now, this is not always the case, but generally speaking, germination needs to happen in a dark environment.
If your weed seeds are getting way too much light, there is a chance that they will not germinate. Like we said, this is not always the case, but it can definitely be a contributing factor.
However, what is interesting is that as soon as the seeds pop open, they can do fine with some light, but just not too much.
There is a really fine line here and it can be hard to gauge. It does somewhat depend on the quality of the seed in question.
4. Temperature & Humidity Issues
Your marijuana seeds need a specific level of temperature and humidity in order to germinate properly, or to germinate at all.
Whatever germination medium you are using, whether water, peat, or paper towel, the temperature needs to be a steady 26 to 28 degrees.
Any hotter or colder than that, and the seeds probably won’t germinate. On that same note, a 70% humidity level is what you are aiming for.
If you are off by too much with either of these factors, the seeds aren’t going to pop open and come to life.
Why Won’t My Pot Seeds Germinate? (Using Soil As A Germination Medium)
Now, although we do not recommend using soil as your germination medium, many people go this way.
Of course, using soil as the medium has the benefit that your seed pops and sprouts in the same place you want it to grow, therefore eliminating the need to transfer the seed from the germination medium into the soil.
However, there are some problems that can arise when using soil for weed seed germination. Keep in mind that some people do plant their seeds directly in the dirt without first germinating them, but this is not a great idea and often results in failure.
Germinating a marijuana seed right in the soil is actually pretty hard and is not recommended. Why won’t my weed seeds germinate when using soil as the medium?
1. You Planted Them Too Deep
One reason why your weed seed might not have germinated in soil is because you planted it way too deep. What is interesting about planting your seed directly in soil for germination, is that it will need a bit of sunlight.
This is because when germinating directly in soil, the seed needs to both germinate and then be able to sprout and grow up past the dirt.
The issue here is that yes, a weed seed needs to have relative dark to germinate, but then needs light in order to grow through the dirt and sprout of the top.
If you bury the seed too deep, once it does open up, the sunlight won’t be able to reach it, and the sprout will therefore quickly die.
So, without just a bit of light, even if the seed does germinate in soil, it still won’t grow up past the dirt.
2. The Soil Has Mold, Fungus, or Insects
Ok, so mold, fungus, and insects of all sorts can easily kill a weed plant in just a couple of weeks. This is a big problem which many growers face, especially indoor growers.
Simply put, if the soil you are using for seed germination has any trace of mold, fungus, or burrowing insects, your seed will most likely die.
It probably won’t ever open up and sprout. However, on the off chance that it does still somehow germinate, it probably won’t live long enough to grow and sprout up past the surface of the soil.
3. The Soil Loaded With Too Much Fertilizer
Perhaps the biggest and most common issue that arises when attempting to germinate your weed seeds in soil is that the soil has too much fertilizer.
Yes, your weed plants will need some fertilizer and nutrients as they grow, but the young sprouts and seeds are extremely delicate.
Generally speaking, even small amounts of fertilizer can burn, destroy, and kill both the seed and the sprout.
4. Other Issues
- Moisture & Temperature – Once again, you might have drowned the weed seed in too much water. On the other hand, if you have not supplied enough moisture, just add some into the soil, and the seed may still germinate.
- Seed Quality – Whether you are using soil or any other medium, the seed may still just be defective on its own.
- Packing Down Too Hard – Now, packing the soil down on top of the seed should be done very lightly. Once the seed goes to germinate, if the soil is packed too tightly, it can prevent the seed from opening up, and if it does open up, the sprout might not be able to force its way up through the tightly packed soil.
Weed Seed Germination – A Quick Guide & Tips
Let’s just very quickly give you a couple marijuana seed germination tips for a fast step by step process.
you want to grow and get some seeds, ensuring that they are fairly round and a good, dark green in color.
- Choose your germination medium, which can be paper towel, water, soil, peat pellets, or similar things to peat pellets.
- Insert the soil into the medium, ensuring that the temperate is steadily around 27 degrees, with a humidity level of 70%, and place this in the dark. for the seed to germinate. Do not wait for longer than a day after the seed has cracked and the first sprout has started to come out to plant it.(if you have not used soil as the germination medium). Waiting too long to plant a germinated seed in soil can cause it to die.
As you can see, there are a number of factors which can affect weed seed germination, with there being a good few issues that can cause them to not germinate. It should be a fairly easy process, but there are some things that can get in the way. We would recommend using peat pellets or the paper towel method for this, as both soil and water as germination mediums usually don’t work too well.

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.
