How To Germinate Cannabis Seeds

One of the most important steps in cultivating cannabis is to understand how to germinate cannabis seeds properly. Once the seeds are in the right environment and have the right amount of moisture, they will begin to grow. They will break out of their shells (also known as the hull or pericarp) and form roots that will help the baby plants take in nutrients from the soil. Cannabis seeds will grow with their roots facing downward and their stems reaching upward. This will enable the young cannabis plants to feed from both the soil and the light.

When you are trying to germinate cannabis seeds, you have several methods to choose from. The first one is to plant them in soil or another growing medium. Seedlings need a certain amount of moisture to germinate. Too little water will prevent germination, while too much will cause the seedlings to rot. Choose the method that gives the seeds the best moisture and humidity levels for the first couple of days. When in doubt, think springtime conditions.

Germination is an essential part of growing marijuana, so it’s crucial to give your plants the best possible start. Although marijuana seeds can be difficult to germinate, these methods will make the process easier. If you’re a first-time grower, it’s vital to ensure the seeds germinate properly. After all, you only have one chance to get it right.

Jiffy Peat Pellets/Pucks

If you are a beginner grower, germination with jiffy peat pellets/pucks may be your best bet.
For cannabis seeds germination, jiffy pellets are an ideal method. They contain dehydrated peat discs that are pressed into a biodegradable mesh. When moistened, the discs swell into miniature sacks of soil. These can then be planted with cannabis seeds. These pellets contain a combination of peat moss, mesh, fertilizer, lime, and ammonium, which can help your cannabis plants grow strong and healthy. Because peat is a sterile medium, you don’t have to worry about soil diseases or fungus killing off your seedlings early on. These pellets can be used in both indoor and outdoor containers. This easy method of growing cannabis can be effective in a variety of climates. The jiffy pellet is also an ideal option for indoor growing, as it provides a controlled environment. Once you have sown the seeds, they will quickly form a root zone. The seeds should sprout tiny roots in about two to five days. Eventually, the seedlings will start to produce true leaves. These leaves are larger and resemble those of the typical cannabis plant. They are also a sign that the cannabis plant is growing and establishing itself.

Paper Towel Method

Another popular technique for cannabis seeds germination is to place the seeds between a sheet of paper towel or cotton wool. The paper towel should be moist but not too soggy. Avoid using paper towels that dry out too quickly, since this could result in the seeds never opening fully. To help maintain the moisture level, check the paper towel daily or even every few hours. This is especially important if you are growing in an area that gets a lot of sunlight or heat. Use a spray bottle to re-moisten the paper towel if it begins to dry out.

The seeds you want to germinate will need to be soaked in water for a day or two before you plant them. This is a critical step as it allows water to get into the seed shell and activate the growth hormones. However, you do not want to soak the seeds for too long as this can cause them to lack oxygen. Usually, 12 to 24 hours will suffice. Once soaked, remove the seeds from the water and cover them with a clean paper towel.

Place the seeds on a paper towel-covered plate in a dark, warm room. You should make sure that the paper towel is moist, and that it does not dry out too quickly. After that, you can water the seeds occasionally so that they remain moist. After this, you will be able to know if your seeds are germinating. Be extra careful when handling these newly sprouted seeds when transplanting to the next medium.

Soaking Seeds in Distilled Water

Another way to germinate cannabis seeds is to soak the seeds in distilled water for 24 hours before planting in your substrate. You can purchase distilled water from the grocery store or a plant nursery. The water should have a pH level between 5.8 and 6.5, which is ideal for germination.

Once you have chosen your substrate, you should prepare the medium for cannabis seeds germination. The soil should be damp, and the seeds should be planted 1/4 to 1/2 inch deep. Once the seeds begin to germinate, they need to be kept moist but should not be over watered. The water should be added in small amounts frequently to keep the soil moist.

Propagation Kits

Propagation kits for cannabis seeds are made to help you get your plants off the ground. Each one includes the tools you need to make sure your plants grow healthy and strong. These kits also include the soil and nutrients that your seeds need to grow. Moreover, they often include a vented dome to keep the soil moist. Aside from this, these kits contain a T5 grow light, which mimics the warmth of the sun, and a heat mat that’s ETL certified.

Cannabis seed propagation kits can be quite inexpensive. These kits usually come with instructions. All you need to do is place your seeds in small pots and then add the germination hormone and nutrient mix. These kits are easy to use and can yield good results. You can also make your own kits or use a propagation machine to help you grow your plants.


The environment of cannabis seeds germination is vital for the success of your cannabis seedlings. For best results, you should keep the temperature between 20 and 25 degrees Celsius, and the humidity level between 60 and 80 percent. You can use a special growers heating mat that can be found at grow shops to increase the temperature for your seedlings. The substrate should remain consistently moist, but also have enough drainage. Never pack down germinated seeds, because they will grow more quickly if they have airflow around them.


For cannabis seeds germination with jiffy pellets, you will need to ensure the right amount of humidity. For best results, you should place the jiffy pellet tray at 24 degrees Celsius, with a relative humidity of around 80%. Place the tray in a dark, damp place, away from direct sunlight and hot areas. You should not plant the seed too deeply; it must have around 1cm of peat surrounding it.

Equipment Needed to Germinate Cannabis Seeds

In order to germinate cannabis seeds, you will need several basic pieces of equipment. These include a heat mat(optional), light, paper towels, jiffy pellets/pucks and propagation kits. Some of these items are not always readily available. It is always best to ask around to get the best deals. Light is the most important component, but you will also need other materials to germinate the seeds successfully.

Light Needed to Germinate Cannabis seeds

Cannabis seeds do not need complete darkness to germinate. However, the cotyledon(the first leaves produced after germination), which develops on the seedling’s stem, is sensitive to light and should be protected from bright light until the plant is about half an inch long. This is to prevent stretching. A healthy cannabis seedling will be short and wide, rather than tall and lean.

Cannabis seedlings need a temperature of twenty to twenty-five degrees Celsius, with 60 to seventy percent humidity. For late flowering, the temperature should be around eighteen to twenty-four degrees, with 60-70 percent humidity. Moreover, the plants need proper temperature to open their shell and send their root into the earth. The best way to provide these temperature needs is with fluorescent lights, especially T5 with a color temperature of 6500K. These lights do not require much power and they also do not produce too much heat. The best way to position these lights is as close as possible to the young plant.

Heat Mats

Heat mats are an essential part of the germination process. They provide the necessary heat to seedlings and help them grow in a controlled environment. Heat mats can be placed on a flat surface near an area with adequate light. The heat source can be natural or artificial. Depending on the type of seed, some seeds require total darkness while others require light for optimal germination. After placing seedlings on heat mats, they should be covered with clear plastic wrap or trays. However, be sure not to overheat the seedlings, as this will cause the growing medium to dry out faster.

Benefits of Growing Cannabis From Seeds Vs Clones

Growing cannabis from seeds has its benefits and drawbacks. For one, seeds have a wider variety of strains than clones. Also, clones can only be used for a short time. Another drawback is that clones are much more difficult to propagate than germination from seed. Moreover, clones are not very easy to find, especially if you live in a place with seasonal climate.

Seeds are easier to obtain and germinate. You can easily order cannabis seeds online. You can also share and trade seeds with other growers. Some cultivators even grow marijuana from seeds in exchange for clones. Cannabis seeds, if grown correctly, can be grown by just about anyone. Seeds do not take up a lot of space and can last for a decade or more. Seeds also make it easier to add variety to your grow. With seeds, you can grow hundreds of different plants at once.
