Cannabis seed germination problems

In addition to the germination rates we also control other important factors of quality such as a high level of healthy seedlings. Seedlings should not appear crippled, feeble, tiny, with dehydrated leaf tips, etc. However, this is a biological product and despite the best production methods a minor % of seedlings (calculations based on 100+ seeds) may not appear healthy and need to be removed. It is therefore always best to germinate an extra seed or two as a back-up, especially if you are only growing a few plants.

There are 3 possibilities:

Cannabis seed germination problems

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.

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.

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.

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 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.

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

Thick shell

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.

Planted too deep

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.
