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.
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.
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.
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.
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.
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.
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!
Soak the seed with H²O²
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.
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.
Left underwater for too long
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.
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!
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.
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.
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.
Using Old or Unsterilized Pots and Soils
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.
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.
Wrong Temperature and Humidity
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.
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.
