Why germinate your own cannabis seeds?

Germinating your own cannabis seeds can be a great way to get started on growing your own supply of the plant. Cannabis germination is the process in which a new plant begins to grow from seed. This is also the first (and very important) step towards a good harvest.

When purchasing seeds, try to make sure you buy the best seeds you can from reputable seed banks. It is important to make sure that they are ripe. They should be dark brown and slightly rough. If the seed is white, pale, or green,
 
it means that they have not yet reached full maturity and may not be viable seeds. The methods
described here work equally well for autoflowering cannabis seeds.

 


How to Germinate Cannabis Seeds

We will be discussing the many methods to germinate your seeds so that you can get the best results. We’ll also be sharing some tips and tricks that we’ve learned along the way.

Starting cannabis seeds is a simple matter. You need just three things: heat, water, and air. But here, it is important to be careful not to overdo it or give less care to the seeds than they require and for you to provide the ideal growing conditions. it’s usually better to germinate seeds indoors so you can control the environment.
 
There are several ways you can sprout seeds, each with its own advantages and disadvantages. To get the maximum result from the plant, you need to initially consider and choose the best way for you to sprout seeds indoors:
 
 
The first thing you need to do is get your hands on some quality cannabis seeds. Once you have your seeds and you are ready to start growing, it’s time to start the germination process.

Germination is the process by which a plant grows from a seed to a cannabis plant it means coaxing them into starting their growth. There are various ways to start seeds—each with its own set of pros and cons:

  1. paper-towel or cotton pad method;
  2. direct into the substrate;
  3. Rockwool cubes and plugs for seedlings;
  4. overnight in the water method.


paper towel method

There are several ways to germinate seeds, but the most popular method is called “the paper towel method.”

  1. Place your seeds on a paper towel.
  2. Fold the paper towel over, making sure the seeds are well covered.
  3. Place the paper towel on a plate, and then put the plate in a warm place.
  4. Wait for the seeds to sprout. This can take anywhere from 24 hours to a week.

Fold the other sheet of paper towel over the top of the seeds, then place the seeds in jiffy or zip-lock bags.

Place the bag on a warm surface (around 21 degrees Celsius is ideal), and check on it daily to make sure that the paper towels remain moist but not soaking wet.

 

To start, find a clean and sterile surface to work on. Next, take a couple of sheets of paper towels and wet

them with distilled water. Once the paper towels are wet, place your seeds on one of the sheets, making sure that they are not touching each other.

Fold the other sheet of paper towel over the top of the seeds, then place both sheets into a zip-lock bag. Place the bag on a warm surface (around 21 degrees Celsius is ideal), and check on it daily to make sure that the paper towels remain moist but not soaking wet.


Once these steps have been completed, it’s time to wait. The seeds will germinate within 1–4 days. Although for some varieties – this period can stretch up to a week. In order for this method to give an excellent result, I would advise you to be careful and periodically check the paper towels and make sure to keep the seeds damp at all times.

 

It is important to make sure the paper towels are kept damp. Make sure you remove any excess water. If they dry out, more water needs to be added. The seeds should sprout after a few days. The seeds will start to produce a little white root poking out of your cannabis seeds—this means they are ready to be transplanted into whichever grow medium you choose. Don’t leave the seeds in the towel too long as the root may get tangled in the paper towels.

This is a simple but risky method. After all, you can damage the taproot when moving the seeds or destroy them if you do not monitor the saturation of moisture.


Cannabis seeds in soil

 

In nature, the cannabis seed germinates in soil and grows with a root growing into the ground. Therefore, some prefer to plant seeds directly into the growing medium or put their cannabis seeds in the soil. The main benefit of this method is that new seedlings are immediately adapted to the environment. Unlike other methods that require some time for the seedlings to adapt, they should start growing by themselves.

 

With this method, I dig a hole in hole in the soil with a pencil , making sure the soil is moist but not saturated and cover the seed. The optimal planting depth is usually 1 to 2.5 cm. During the germination of cannabis seeds, seedlings should be kept warm. This can be achieved with a heating pad or grow light.

 


Using seedling plugs

Plug plants are seedlings that have grown in trays of tiny cells of peat or rockwool after being germinated as seeds. When the roots are big enough, they may be simply pulled out of the trays and either planted in the ground or transplanted into bigger pots.

Some growers prefer to start their seeds with this method as it is an efficient and reliable way. All you have to do is place feminized seeds in a plug and just add water. As soon as your seed is in the right environment, it should start to grow within 24 hours. The seeds will produce a nice root system, and one of the great advantages of this method is you have a young plant ready to grow. and it can be placed directly into your growing medium.

The main disadvantage to growers who germinate their seeds this way is that such plugs can dry out after a week or so and become unusable.

The seeds in water: the overnight method

 

The whole point of the method is to simply place the seeds in a glass of warm water overnight. I especially recommend overnighting when using older seeds and hard seeds. The soaking process can be a great way to revive your old or poorly stored seeds.

When placed in water, the seeds first float for several hours and then sink to the bottom. The result should be a white root stem.Your seeds should germinate within this time. Otherwise, those who have not yet grown will drown. If the seeds don’t sprout after 36 hours, place them in a warm and humid spot to finish germinating. For example, you can combine this method with the paper towel or cotton pad method.


Transplanting Germinated Marijuana Seeds

 

This is suitable for all methods except direct planting. When the seeds begin to sprout, you need to act quickly. It’s time to move the seeds to your growing medium. I prefer to use small pots to start with. It is important to make sure the pots are sufficiently filled with loose potting soil.

 

Next, using a pencil, you need to make a small hole with a depth of about half a centimeter. The main thing in the process of transferring seeds to the soil is not to hurt or break the root rod. To avoid injury to the cannabis sprout, the seeds are placed in the prepared hole with tweezers. We then add a thin layer of soil on top.


In order for further germination of cannabis to be successful during the first few days, you need to use a spray bottle to water the seeds, because adding too much water can drown them. Light also plays an important role in this process. Good lighting and warmth improve the germination rate of seedlings and the first set of leaves. These leaves may remain yellow as long as they are not exposed to sufficient light.

 

All seeds (even from the same batch) grow at different rates. Some will inevitably fail, while others will prosper. The main thing is not to be disappointed if a few seeds do not sprout – this is an integral part of the growth process.

How to know if your cannabis seeds are ready to germinate

The vast majority of seeds on the market are ready to grow as soon as you get them. However, there are a small number of breeders who are now selling what are known as “pre-sprouted” or “gelatinous” seeds. These seeds have been soaked in a special solution that encourages the germination process, and they will usually grow within 24 hours if they are kept at the correct temperature.

If you’re not sure whether your seeds are ready to germinate, there is a simple test you can do at home. Just place a few seeds in a glass of water and wait for 24 hours. If the seed sinks to the bottom, it is ready to be planted. If it floats, it is not yet ready and you should wait a few more days before testing again.

The best soil to germinate seeds

One of the most important things to know to germinate your cannabis seeds successfully is the type of soil you need to use. Not all soils are created equal, and different strains of cannabis have different soil requirements. In general, though, you want to use a high-quality potting mix that is light and airy. Avoid using garden soil, as it is often too dense and can compact around the roots of your seedlings, suffocating them.

The best soil for growing your own cannabis will have a mix of perlite, vermiculite, and coco coir. This mix provides good drainage while still retaining some moisture, which is vital for germination. You can find premixed potting soil at most garden stores, or you can mix your own. If you choose to mix your own, make sure you sterilize your materials before mixing them together.

Once you have your soil ready, and you are ready to grow cannabis, it’s time to plant your seeds! Fill up your planting containers with moistened soil, then plant two or three seeds per container about ¼ inch deep. Be sure to label each container with the strain name and the date planted so that you can keep track of them. Once planted, cover the containers with clear plastic or a clear lid to help retain moisture and humidity. Place them in a warm spot out of direct sunlight until they germinate.

The best temperature to germinate marijuana seeds

The ideal temperature for sprouting seeds is between 21 and 26 degrees Celsius (70 and 80 degrees Fahrenheit). This temperature range will allow the seeds to germinate quickly and evenly. If the temperature is too high or too low, the seeds may not germinate at all, or they may germinate unevenly.

The best humidity for germination

Relative humidity (RH) refers to the amount of water vapor present in the air. Cannabis seeds need a certain level of RH in order to germinate properly. The ideal RH for germinating cannabis seeds is between 60 and 75%.

Too much or too little moisture in the air can prevent seeds from germinating. If the air is too dry, the seed will not be able to absorb enough water to start the germination process. If the air is too humid, the seed may start to rot before it can germinate.

Cannabis seeds can be sensitive to fluctuating humidity levels, so it’s important to keep the relative humidity as stable as possible during the germination process. Some people also like to use a humidity dome, which is a clear plastic cover that goes over the container and helps trap moisture inside. You can find these at most gardening stores or online.

How to troubleshoot problems when germinating cannabis seeds

It’s important to keep an eye out for any problems that might arise. Here are some common problems and how to troubleshoot them:

Seeds that float: This usually means that the seed is not viable and will not grow. Throw these seeds out and start with new ones.

Seeds that sink but do not germinate: This can be due to a number of factors, such as old seeds, incorrect temperature,, or too much moisture. Try starting with new seeds, adjusting the temperature, or reducing the amount of moisture.

Seeds that do not break through the shell:

This can be due to an incorrect temperature, too much moisture, or not enough light. Try adjusting the temperature, reducing the amount of moisture, or increasing the amount of light.
