There are many different ways to germinate cannabis seeds, but germinating them in water is one of the most popular and effective methods. All you need is a glass of water and a few days patience, and you’ll have healthy seedlings ready to plant.

Here’s a step-by-step guide to germinating cannabis seeds in water:

1. Fill a glass with room-temperature water. You can also use distilled or bottled water if you’re concerned about the quality of your tap water.

2. Place your seeds in the water. You can put them all in at once, or germinate them one at a time to give each seed its own space.

3. Place the glass of water in a warm, dark place. A windowsill or cabinet top are both good options. Avoid placing it in direct sunlight, as this can overheat the water and damage the seeds.

4. Check on your seeds every day or so, and add more water if necessary to keep the level consistent. The seeds will start to splinter and crack as they absorb water and begin to germinate.
Some growers like to remove the seeds from the water once they’ve started germinating, but leaving them in is perfectly fine as well.
5. Once the seeds have fully germinated (usually after 3-5 days), they’re ready to be transplanted into soil or another growing medium. Be sure to handle them carefully, as their delicate root systems can easily be damaged

What You Will Need

To start, you will need the following materials:

Cannabis seeds
A glass or cup
A towel or paper towel

1. Begin by filling your glass or cup with room temperature water. You don’t want the water to be too cold or too hot, as this can shock your seeds and prevent them from germinating.
2. Next, add your cannabis seeds to the water. You can add as many or as few as you like, but keep in mind that each seed will need its own space to germinate properly.
3. Once all of your seeds are in the water, give them a gentle stir to make sure they are all submerged.
4. Then, cover your glass or cup with a towel or paper towel and set it aside in a warm, dark place for 24-48 hours.
5. After 24-48 hours have passed, check on your seeds to see if they have begun to germinate. If they have, you will see a small white root poked out from the shell of the seed. If they have not, simply leave them to soak for a few more hours and check on them again later.
6. Once your seeds have germinated, it’s time to plant them! Fill a small pot or container with moistened soil and gently press each seed about ½ inch deep into the soil. Make sure not to plant them too deep, as this can prevent them from emerging later on.
7. Water your newly planted seeds well and place them in a warm, dark place until they sprout and begin to grow!

The Process

To germinate your cannabis seeds in water, you will need the following materials:

-A cup or small container
-Cannabis seeds
-Paper towel

Fill your cup or container with room temperature water. It should be deep enough to completely submerge your seeds, but not so deep that they will float to the surface. Add your cannabis seeds to the water and let them soak for 24 hours.

After 24 hours, remove your seeds from the water and place them on a paper towel. Gently pat them dry and then place them in a dark, warm location. Check on them daily, and within a few days, you should see taproots emerging from the seeds. Once the taproots are about ¼ inch long, they are ready to be transplanted into soil.


To conclude, it is possible to germinate cannabis seeds in water. However, it is not recommended for beginners as it requires more attention and knowledge than other methods. You must be vigilant to ensure that your seeds do not get moldy or rot, and that they have sufficient oxygen to germinate properly. If you do decide to try this method, make sure to start with a small number of seeds so that you can monitor them closely.
