How to germinate cannabis seeds
Germination is the process in which a new plant begins to grow from a seed. Also referred to as “popping,” germination is the very first step in starting your cannabis garden.
Cannabis seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
When acquiring seeds, you want to make sure they are matured and that they appear dark brown with lighter accents and a hard feel. You don’t want a seed that feels fresh and looks green, which indicates that the seed hasn’t reached full maturity.

Once you have your cannabis seeds, make sure you have the space necessary to allow your plants to grow and be healthy. Don’t pop seeds when you are unsure of your grow space, time availability, or intention with your garden.

What’s the best way to germinate cannabis seeds?
Cannabis seeds require three things to germinate: water, heat, and air. Because of this, there are many methods to germinate your seeds. The most common and simplest method involves the use of paper towels saturated in water.
For this method you will need:
- Two clean plates
- Paper towels
Take four sheets of paper towels and soak them with distilled water. The sheets should be soaked but shouldn’t have excess water running off.
Take two of the paper towels and place them on a plate. Then, place the cannabis seeds at least an inch apart from each other and cover them with the remaining two sheets of water-soaked paper towels.
To create a dark, protected space, take another plate and flip it over to cover the seeds (like a dome).
Make sure the area they’re kept in is warm, somewhere between 70-90°F.
After these steps have been completed, it’s time to wait. You can check the paper towels to make sure they’re still saturated, and if they seem to be losing their moisture, you can apply more water to keep the seeds happy.
Some seeds germinate very rapidly while others can take several days. You know a seed has germinated once the seed splits and a single sprout appears.
This is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination. It’s important to keep this area sterile, so don’t touch the seed or taproot as the seed begins to split.
Transplanting germinated cannabis seeds
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium. Small 2-inch pots are a good place to start.
Fill the pots with loose, airy potting soil and poke a hole in the middle about a quarter-inch down using a pen or pencil.
To transfer the seed, use a pair of tweezers to gently pick it up, then drop the seed in the hole with the taproot facing down. Lightly cover it with soil.
Next, you’ll need to water the soil. Initially, use a spray bottle to provide moisture without over-saturating the soil. You want to give the seed water, but over-watering can suffocate and kill the delicate sprout.
Pay attention to the temperature and the moisture level of the soil to keep the seed happy, and within a week or so you should see a seedling begin to grow from the soil.
Germinating seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones and which to breed with other strong plants to create a seed bank of your own.

How to properly plant weed seeds after germination?
In our previous blog “Germinating marijuana seeds” you could read how to germinate marijuana seeds. Germinating is the preparation process to successfully grow a cannabis plant.
As soon as the seed has a root you can plant the seed. Planting cannabis seeds is not difficult at all. Yet, it does require some basic knowledge and skills. This article will help you to plant your cannabis seeds so you start your grow in the best way possible.
Why germinate before planting?
Of course you can place a cannabis seed directly in the soil, but this has three disadvantages:
- The seed can become too moist, causing it to rot.
- The seed stays too dry so it can’t grow. And because the seed is under the ground you can’t control it.
- You can’t determine the direction of growth of the root. In short, our advice is to germinate before you start planting cannabis seeds.
When you should plant your cannabis seeds
When you have followed our advice your seeds have sprouted and you can start planting your seeds. Make sure the seeds have a root of at least 1.5 to a maximum of 2.5 centimeters. Are you planting the germinated cannabis seeds too early or too late? Then there is a chance that the plant dies at a young age. It is therefore important that you plant the germinated seeds as soon as the root is long enough.
Always plant indoors first
Good to know is that you first plant and your cannabis seeds indoors, even if you will eventually grow them indoors or outdoors. The reason to let young female plants grow indoors first is because they are fragile in the beginning. A gust of wind can blow the plant over or be damaged by animals. Indoors you have a safe environment where the young seedling can become strong enough before it is moved outside.
What do you need to plant germinated cannabis seeds?
Fortunately, you don’t need much to plant your germinated cannabis seeds. A lot of things are already standard available in your home and otherwise you can buy them at any garden center.
What you need:
- Lightproof pot or mug of 1 to 2 liters
- Potting soil (light mix for cuttings and seedlings)
- Pen or pencil
- Germinated cannabis seeds
- Plant sprayer
Are all items present? Then the real work starts: planting your cannabis seeds. Use the step-by-step plan below.
How to plant marijuana seeds in 4 simple steps?
In four simple steps you will learn how to successfully plant cannabis seeds. Whether you’re an advanced or beginner, want to grow indoor or outdoor seeds, the process is always the same. Follow the steps below carefully and you’ll grow your own beautiful cannabis plant.
- Fill the pot or cup with potting soil
- Make a dimple in the earth
- Place the weed seed in the dimple
- Cover the seed with a thin layer of earth
Step 1 – fill the pot or cup with potting soil
Fill the cup or pot up to 1 cm below the edge with potting soil (light mix for cuttings or seedlings). Do not add extra nutrients. Seedlings get more than enough nutrients from the soil. Too much nutrient can have a negative effect.
Step 2 – make a small dimple
To plant your cannabis seeds you make a dimple in the growing medium. You can easily do this by inserting your pen or pencil into the soil. The tiny hole should be about 2 to 2.5 cm deep. If you mark this on the side of your pencil, you can be sure that the depth is good.
Step 3 – place the cannabis seed in the dimple
Use your fingers or tweezers to place the weed seed in the hole. Do this carefully, because if you squeeze too hard you can damage the germinated seed. The root of the seed should point downwards (!).
Tip: did you use damp kitchen paper towels when germinating and is the root of the seed attached to it? Do not pull it loose, but first spray the seed again with water. You will see that the seed now easily lets go.
How should you plant the weed seed?
Make sure that when you plant your cannabis seed, the root disappears as deep as possible into the hole. The skin of the seed should be at least 0.5 cm below the surface.
Step 4 – cover the seed with a thin layer of soil
Did you put the seed in the tiny hole? Great! Cover the seed carefully with a thin layer of soil. Do not press the soil! A few millimeters of soil over the seed is more than enough to block the grow lights or sun. Spray the surface moist with the plant sprayer and place the cup or pot in the window sill or under light. After a few days the seeds will grow out the surface.
Your cannabis seeds have been planted! How to proceed?
You’re already on your way to grow your cannabis plant. But maybe you want to continue growing marijuana plants outdoors in the end.
As said before, you do the beginning of the growing process indoors and that takes about two weeks. After two weeks the plant is strong enough to repot to another place or larger pot to continue growing. How to do this, we tell you in the blogs:
