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!

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.
