There are many methods of germinating cannabis seeds. Some are less risky and less complicated than others, so choosing the right approach is very important. In this article, we will look at a simple and effective method - germination in a glass of water.
What do weed seeds need to germinate?
Water, heat and air (oxygen) are all that cannabis seeds need to come out of dormancy and sprout. Fertilizer, special hormones, and secret supplements are not necessary as Mother Nature provides the seeds with a stored food supply to usher them through the germination. Strong, viable seeds germinate in two to seven days. As the seed germinates, the seed's protective shell splits open and a tiny white rootlet (taproot) pops out.
Germinating Weed Seeds in Water – Step by Step Guide
Germinating pot seeds in water is very simple and effective method that is highly recommended by FastBuds Seeds Company. This method is especially effective for seeds with a harder shell or older seeds. Here are all the steps for germinating pot seeds in water:
- Get a glass of water.
You can use tap water or distilled water, whichever one you prefer. Just make sure to leave the glass of water at room temperature first. Do not use hot or cold water. Hot water can easily damage your seeds. Ideal temperature is around 21-26 C.
- Place the seeds in the glass.
At first, seeds will often float on the surface. They should sink to the bottom of the container after a couple of hours. Soaking ensures that water penetrates the protective shell to activate growth hormones.
- Place the glass in a dark warm place and let the seeds soak.
After a couple of days, you should see the radicle. Remember that some seeds may need longer until you see the radicle coming out. If they have not sprouted after 72 hours, add a few drops of hydrogen peroxide to kill accumulated bacteria in the water and return to the darkness for 2 more days.
- Plant your germinated seeds.
When the taproot is around 2-3mm long, carefully get seeds out of the glass and plant them in soil. Make a 0.5-1cm deep hole in the soil, place your seed root pointing down and cover it with more soil. Lightly spray the area.

What water pH is best for the germination of weed seeds?

Should I use hydrogen peroxide in water to germinate pot seeds?
According to recent studies, hydrogen peroxide solution is thought to increase germination rates and is therefore considered an effective medium for germination. Sprouting your seeds in a glass of water with a tablespoon of hydrogen peroxide mixed in can help sprout the seeds more efficiently as the solution breaks down the seed coat and allows more oxygen to get inside.
