Why are my seeds not germinating? With our germination troubleshooting guide, you can get to the bottom of why your weed seeds aren’t popping. Avoid these germination mistakes and get your grow off to a great start!
When planting directly into the soil, don’t bury your seeds too deep. If they’re too far down, they won’t have access to enough oxygen, and moisture in the soil can overpower them and cause them to rot.
WHY YOUR CANNABIS SEEDS AREN’T GERMINATING
Just like food, seeds are living organisms that need to be stored properly, otherwise they’ll degrade, die, or won’t germinate. When storing your seeds, keep them away from light, extreme temperatures, and humidity. A dark cupboard with stable temperatures is fine. For long-term storage, place seeds in a sealed container and store them in the fridge.
Keeping the above in mind, seeds do need moisture to germinate. Keep your soil moist but not damp. The best approach is to use a hand sprayer with a fine mist setting. Use a transparent germination hood or cling film to keep the soil from drying out.
If you allow your seeds to germinate for too long, transplanting them safely will become difficult. The reason for this is that the longer the roots are exposed to air and light, the more likely they are to become damaged. Moreover, the longer the taproot, the higher the risk for accidental damage when transplanting.
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.
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.
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 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.
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.
