The importance of germinating your cannabis seeds

Germination is the process of coaxing a cannabis seed to sprout and produce a new plant. Seeds that have been properly germinated will produce young seedlings that are vigorous and healthy, strong enough to start the journey from a tiny seedling into a full-grown adult plant. While it may seem like a small and simple task, germination is actually a crucial first step in growing cannabis, and one that should not be taken lightly!

There are many different methods of germinating cannabis seeds, but the most important thing to remember is that each method will have its own set of instructions that must be followed carefully in order for it to be successful. Some methods may be easier than others, but all of them require some level of attention and care.

The most important thing to remember when germinating cannabis seeds is to start with healthy, viable seeds. Seeds that are old or have been damaged in some way (such as being crushed or dried out) are less likely to germinate successfully. If you’re not sure if your seeds are still good, there are a few simple tests you can do at home to check their viability.

Once you have your healthy seeds, the next step is to choose a germination method. The two most popular methods are soaking them in water overnight or using the paper towel method, both of which are described in detail below.

Whichever method you choose, just be sure to follow the instructions carefully and do not hesitate to ask for help if you need it. Germinating cannabis seeds may seem like a daunting task at first, but with a little patience and practice, you’ll be able to do it like a pro in no time!

The best way to germinate your cannabis seeds

The best way to germinate your cannabis seeds is to start with a good quality seed. You should also make sure that you have the proper equipment and supplies. Once you have a good quality seed, you will need to start by soaking the seed in water for 24 hours.

Soaking your seeds

The first step is to find a container that is big enough to comfortably fit all of your seeds while still allowing you to easily stir them around. You will also need a way to filter out the water, such as a coffee filter or cheesecloth. Place your seeds in the container and add enough water to cover them by about an inch. Allow the seeds to soak for 12-24 hours, stirring occasionally.

Check on your seeds periodically to make sure they are still covered in water. If they start to float, simply push them back down with your finger. After 12-24 hours have passed, remove the seeds from the water and rinse them off with fresh water. Gently pat them dry with a paper towel and place them on a plate lined with a coffee filter or paper towel.

Cover the plate with another coffee filter or paper towel and set it in a dark, warm place. Check on your seeds daily, making sure they are still moist but not waterlogged. In 3-7 days, you should see taproots emerging from the seed coatings. Once the taproots are about ¼ inch long, you can transplant your seedlings into individual pots filled with soil or another suitable growing medium

The Paper towel method

This is probably the most common method of germinating cannabis seeds. All you need is a couple of paper towels, some water and of course your seeds.

1. Get two sheets of paper towel and wet one of them until it’s damp but not dripping.
2. Place your seeds on the damp paper towel, making sure they’re not touching each other.
3. Cover the seeds with the dry paper towel.
4. Put the whole thing somewhere warm (around 21-25°C is ideal), out of direct sunlight and where you can check on it regularly.
5. After a few days, you should see roots starting to come out of the seeds. At this point, they’re ready to be transplanted into soil or another growing medium.

If you’re not sure when your seeds are ready to be transplanted, it’s better err on the side of caution and wait a few extra days. Once the roots are about 1-2cm long, they’re ready to be moved into their final growing medium

The water glass method

This is probably the easiest way to germinate your seeds. All you need is a glass of water (distilled works best), a small cup, and a paper towel.

-Start by soaking your seeds in the glass of water for 12-24 hours. This will help them to absorb enough water to start the germination process.

-After 12-24 hours, remove the seeds from the water and place them on the paper towel.

-Fold the paper towel over the seeds, making sure they are fully covered.

-Place the paper towel inside the small cup, making sure that it stays moist (you can mist it with a little water if necessary).

-Place the cup in a warm location out of direct sunlight (around 21°C or 70°F is ideal).

-Check on your seeds daily, making sure that the paper towel stays moist. After 3-5 days, you should see roots beginning to emerge from the seed coat. At this point, you can transplant them into soil or another growing medium.

How to tell if your seeds have germinated

The first step in growing your own cannabis is to germinate your seeds. There are a few different ways to do this, but the most important thing is to make sure that your seeds are fresh and viable. There are a few tell-tale signs that your seeds have germinated successfully. Let’s take a look.

The taproot

The first thing to look for when germinating your cannabis seeds is the appearance of the taproot. This is the very first root that comes out of the seed, and it’s what all the other roots will grow from. The taproot is white or light-colored, and it’s usually visible within 12-24 hours of planting your seeds.

The white shoot

If you’ve followed the germination process to a tee and your seeds have been placed in optimal conditions, you should see a white shoot emerging from the seed within 24 to 48 hours.

The white shoot is actually the taproot, and once it breaks through the seed coat, it begins to grow downward in search of water. The shoot is usually about ¼-inch long when it first appears.

If you don’t see the white shoot within 48 hours, it doesn’t necessarily mean that your seeds have failed to germinate. Sometimes, the taproot doesn’t break through the seed coat right away and it can take a few days for it to emerge.

If you’re not sure whether or not your seeds have germinated, gently remove one from its growing medium and check for the taproot. If it’s there, congratulations — your seed has germinated!


If you’re having trouble germinating your cannabis seeds, then this guide is for you. We’ll go over some of the most common problems that people have with germinating seeds, and how to fix them. By the end of this guide, you’ll know how to germinate your seeds successfully every time.

My seeds haven’t germinated yet!

It can be disheartening waiting for your cannabis seeds to germinate, especially if it’s taking longer than you expected. The good news is that there are a few things you can do to troubleshoot the situation.

First, make sure that you’re using fresh, high-quality seeds. If your seeds are old or have been improperly stored, they may be less likely to germinate.

Second, be sure to follow the instructions for your particular seed type and germination method. With cannabis seeds, it’s important to avoid letting them dry out during the soaking/germination process. Make sure you’re using fresh, room-temperature water and soaking for the recommended amount of time.

Finally, don’t give up! Cannabis seeds can be notoriously finicky, so it often takes a few tries to get them to germinate successfully. Be patient and keep trying, and eventually you should see those little sprouts poking through the soil!

My taproots are too long!

If your taproots are too long, it’s likely because you’ve waited too long to transplant them. When roots get too long, they become fragile and can easily break. If you’re transplanting into soil, make sure to carefully loosen the soil around the roots before transplanting. If you’re transplanting into a hydroponic system, make sure to gently rinse the roots before transplanting.
