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!
