Top 5 Germination Mistakes To Avoid When Growing Weed

Germinating cannabis seeds is necessary in order to sprout seedlings that develop into mature, healthy cannabis plants. However, complications with light, humidity, heat, and more could result in cannabis seeds failing to sprout. Find out what to avoid to ensure successful germination.

Germination is where the magic begins. Cannabis seeds must first germinate in order to sprout and begin their journey as living, breathing plants. However, if the germination process is done incorrectly, or is thwarted by some other variable, seeds can fail to sprout, leaving you with useless, spent seeds instead. Here are the top five mistakes to avoid when germinating cannabis seeds.

GERMINATING BAD SEEDS

One of the most common reasons seeds fail to germinate is because they are simply duds. Typically, healthy cannabis seeds should look a specific way and be of a specific colour. Viable seeds will appear round, not flat, and should be a beige to dark brown colour with subtle tiger striping. Seeds that have been flattened or are pale in colour may have a tough time sprouting into healthy cannabis plants.

Seeds that have been improperly stored may also fail to germinate. These tiny packages of DNA prefer to be kept in a cool, dark place with moderate humidity. Exposing them to heat, light, or extreme humidity levels (both high and low) could result in seeds losing their viability. As long as you source your seeds from reputable seedbanks and store them appropriately, you shouldn’t have to worry about bad seeds ruining your chances of successful germination.

TOO MUCH LIGHT

Generally speaking, seeds require a dark environment in order to germinate. After all, in nature cannabis seeds find their home in the dark embrace of soil. It can be hard to determine exactly how much light is too much for your seeds; however, err on the side of caution and germinate out of direct light. There’s no need to use your grow lights until after germination has occurred.

It is also likely that the quality of your seeds will affect their ability to handle direct light. Seeds that are already having a tough time germinating will have an even worse time doing so if they are exposed to excess light.

TOO MUCH OR NOT ENOUGH WATER

The amount of water you supply your seeds during the germination process will also affect their ability to successfully germinate. Some growers attempt to germinate by “drowning” them in a glass of water. While this ensures they will not go thirsty, it can actually be more harmful than helpful.

Once they pop, seedlings are very delicate and must be watered carefully. When germinating, your medium should be damp, but not overly wet for best results. On the other hand, a dry environment is basically a death sentence for your seeds. They need a constant source of moisture to sprout, otherwise they’re good as duds.

TEMPERATURE PROBLEMS

Cannabis seeds require a specific temperature range in order to germinate. Regardless of the germination medium you are using (soil, paper towels, etc.), the temperature in the environment should consistently sit in the 26–28℃ range. Seeds need to be kept warm during the germination process. At no point during germination should seeds be exposed to temperatures below 20℃.

There are some techniques that can be used to ensure your seedlings remain in this temperature range. Some growers choose to use special warming mats that can be set to a specific temperature and placed underneath the seedling containers. Another strategy is to place a timed heater close to your seedlings to warm them up occasionally. Once your seeds have sprouted, they will be much more resilient to fluctuations in temperature.

GERMINATING IN SOIL

Many people choose to germinate their seeds using paper towels. However, others choose to do so directly in soil. Of course, germinating your seeds in soil isn’t inherently bad, but it can come with its own set of challenges, and is generally not recommended unless necessary.

For instance, the upper layer of soil can dry out within 48 hours, making it more difficult to give your seeds the right amount of water they need without overdoing it. Giving your soil too much water during germination could result in the seed rising up or dropping down further, inhibiting its viability. Moreover, seeds that are planted too deep in the soil could experience a host of complications. They could suffocate before coming into contact with enough oxygen, and be unable to access sufficient light to progress into the seedling stage of their life cycle.

Seeds may also be unable to germinate if the soil they are planted in contains contaminants. Mould and pests can easily kill a mature, healthy weed plant within just a matter of weeks. It should come as no surprise then that they could also prevent a small seed from germinating. If your soil contains traces of these contaminants, it is possible that your seed will never actually open and sprout. This also applies to fertilisers. Even small amounts of fertiliser in your soil can effectively kill your seed, making it completely useless.

Germination

You bought beautiful Premium Pro Seeds from Suzy Seeds and of course, you want to get started. First, you have to germinate the seeds. Below, I will discuss my favorite way how to germinate cannabis seeds extensively, but also suggest other good methods. Suzy Seeds exclusively sells feminized cannabis seeds, so you don’t need to remove male plants, which applies also to autoflower cannabis seeds. It’s good to know that a cannabis seed does not need light to germinate. What is important, though, is a humid environment and an ambient temperature of around 20 °C. In general, there are three ways to germinate cannabis or marijuana seeds:

– In a cup of water

– On a damp surface

– In soil

How long does it take cannabis seeds to germinate in general? Or how do we germinate autoflowering seeds? The time of germination of marijuana seeds depends on the method of germination we apply, but autoflowering seeds germinate in the same way and time as feminized or regular cannabis seeds. My favorite way to germinate the seeds is to put them in a cup of water and then between a damp paper towel or tissue. This goes well in 99% of the cases. That is why I will more extensively describe this first way.

We recommend not to touch the seeds or the seedlings with your hands. If you do anyways, make sure your hands are clean and if possible use plastic gloves.

Suzy’s Tip: Try your germintion method on a couple of seeds (maximum 3). This way, you can test if your method works well. Often a wrong germinating method is used and the seeds don’t germinate. Do you want to germinate your seeds in a different way? Continue reading.

Germinating cannabis seeds in a cup of water

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Use a clean room and area for the germination process. Fill a cup with water and put the cannabis seeds in it. After 3 to 5 days, the seeds should pop open and a tiny root should come out. As soon as the sprout is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Planting the germinated seed has to be done with lots of care and attention. Put them 0.5 to 1 cm in the soil with the root down. This way, the root (the white sprout) will more easily grow downwards.

Germinating cannabis seeds on a damp surface

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Put the cannabis seeds on a surface that holds moisture, like wadding, paper towel or tissues on a saucer. Moisten the surface well, but avoid making it too wet. The moisture evaporates quickly at room temperature, so check during the period that the seeds will germinate if the surface is still damp enough. You can also cover the seeds with damp wadding or tissues and another saucer on top. Because of the moisture that gets into the seeds, they are activated and start to germinate. As soon as the germ is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Put them 0.5 to 1 cm in the soil with the root down. This way, the root will more easily grow downwards.

Germinating cannabis seeds in soil/compost

Direct germination of marijuana seeds in the soil is a commonly used method. You don’t have to handle the fragile plant, so it is not disturbed in its growth process. However, the chances that the seeds will germinate are lower than when applying the other methods. When using this method, it is important to use good soil. You can inform yourself about the different types of soil at your local grow shop. Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or not optimally germinate. Put the cannabis seed about 1 cm deep in the soil. Cover the hole with some soil and gently press. The soil needs to be light so that the plant can easily grow to the surface. Solid soil is hard to penetrate for the roots and will cause a delay. The weed seeds will germinate under the ground and will come to the surface after 4 to 10 days. There are also more germination methods that can be applied.
