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.
Follow these simple steps on the best way to properly germinate your cannabis seeds, and find out how to transplant the seeds to soil after germination.

How long does it take to germinate cannabis seeds?
Before you get started it is good to know how long the germination of marijuana seeds takes. The germination time depends on the seed and method so there is no unambiguous answer to this, but germinating weed seeds usually takes 2 to 4 days.
The best way to germinate marijuana seeds
Although different germination methods exist, not all methods are equally successful. An example of a less efficient method is to plant the seed directly into the soil. This method is not recommended for two reasons.
First of all because non-germinated seeds can rot in the soil. Moreover, with this method you cannot determine the direction of the root.
Fortunately there are several efficient methods so let’s quickly tell you how best to germinate your cannabis seeds.
How to germinate weed seeds? Use our step-by-step plan!
We advise to germinate cannabis seeds indoors. Not in the light, but in the dark. Also when you want to grow outdoors. The root should not be exposed to (sun)light. Moreover, a young plant is young and often not resistant to changing weather conditions.
The best, fastest and safest way to germinate your marijuana seeds is to use two methods one after the other:
- Method 1: Germinating cannabis seeds in a glass of water
- Method 2: Further germination between damp kitchen paper
What do you need?
Before you start the germination process, it is useful to have all the supplies ready. This way you will be well prepared. You can read exactly what you need below.
- Drinking glass
- Two ceramic plates
- Kitchen paper or cotton wool
- Plant sprayer
- Optional: tweezers
Did you set everything up? Then the real work can begin.
Step 1: germinating weed seeds in a glass of water
For a successful germination process we advise you to first soak your seeds in water before germinating them further between damp kitchen paper. By soaking your seeds beforehand, the skin of the seed becomes soft and the root can easily come out.
How to germinate marijuana seeds in a glass of water?
Grab a glass and fill three quarters of it with lukewarm water. Attention: no cold or warm water. You can also use sterile water, but tap water is also fine. Drop your seeds carefully into the water. The seeds will first float (for a few hours) and then sink to the bottom of the glass. Your seeds don’t sink? Then carefully push the seeds to the bottom with the top of your finger. If the seed does float up again, wait for 2 hours and then carefully push the seed down again. Make sure you don’t crush the seed on the bottom.
Put the glass with the seeds in the dark for 18 to 36 hours with a temperature of 19 ° C to 25 ° C. A kitchen cabinet or other dark place is fine.
After a maximum of 36 hours, all seeds are sunk and often already partially germinated. Seeds that start germinating can be recognized by a broken skin where the white of the root becomes visible. In any case, do not worry if your seeds do not start germinating yet. The germination process has not yet been completed.
Step 2: Germinating your cannabis seeds with damp kitchen paper or cotton wool
After step 1 is completed you proceed to step 2. In this step you’ll need two ceramic plates and two sheets of kitchen paper. Do not use toilet paper, but real kitchen paper. Kitchen paper is thick enough to retain moisture for a longer period of time, which is very important.
Step 2 actually consists of 6 tasks. Take a look at the tasks below.
- Grab a plate and put two sheets of kitchen paper on it. The kitchen paper should completely cover the plate.
- Carefully pour your seeds with the water on the kitchen paper.
- Fold the paper towels over the seeds so that the seeds are between the paper towels. Make sure the seeds are in contact with the wet kitchen paper.
- Take the other plate and place it upside down on the plate with the seeds to create a dark space. Do not align the edges of the plates exactly. The seeds need oxygen to germinate.
- Check every 5 to 8 hours that the kitchen paper has not dried and if necessary re-wet the kitchen paper using the plant sprayer.
- After 24 hours, check whether the seeds have germinated. Is that not the case? Then check every 12 hours whether the seeds have germinated and keep the kitchen paper moist at all times.
Note: some seeds take 48 to 72 hours to germinate, but it can even take 168 hours (7 days). Patience is therefore required.
Step 3: Your weed seeds have germinated, and now what?
After germination and as soon as the root is about 1.5 to 2.5 cm long, the seed is ready to be planted. Want to know how to do that?
