How to Germinate Marijuana Seeds

There are many ways to germinate your seeds, like using a cup of water, the towel method, directly into the soil and more…

Germinating with a Cup of Water

You can germinate your seeds simply in a cup of water with a temperature of 22-25 degrees Celsius. After two or three days you will see a little white root coming out of the seed.

Then you need to carefully take the seeds from the water and put them with the rootlet down into the ground and no deeper than 1 cm. The stalk that comes out of the seed is not the plant but the rootlet.

Be aware that the water can get infected ending up killing your seed and sometimes It can be hard to keep the temperature at 22-25 degrees Celsius.

Towel Method

This is one of the most common ways to germinate your weed seeds. You just take a plate and put some paper towels or cotton wool on it and soak it with water. Pour any excess water from the plate and put the seeds on the soaked towel/paper, and put another plate on top (reversed). This way the water doesn’t evaporate too quickly. Just make sure you keep the toilet paper or cotton wool moist. Between two and four days the seed will germinate.

If you germinate this way you have to remember the taproot will develop microscopic little roots that attach themselves to the fibres of the paper. These little filaments are often torn off when the seeds are removed from the paper towel.

Into the Soil

And of course you can just put the seed right into the soil, water it and put some Saran wrap over it to keep the soil from drying out. This way you don’t have to repot if your plant starts to grow, though it can be hard to regulate humidity. Also, you can’t check, so you just have to wait and hope the seed will germinate (which can take up to a week).

Personally, I prefer to do it the easy way with spongepots and a propagator.

Take about 200 ml of water with a temperature of around 25 degrees Celsius (77 degrees Fahrenheit) and put the bacto in it while stirring it well and pour it over the spongepot (bacto is included with the spongepots).

In the meantime while the spongepots are soaking up the water, I start building my propagator.

This combination of spongepots and the way of germinating is easy and foolproof. The propagator won’t  take long to build, and it comes with batteries and perlite, so you can make a quick start. The Propagator Pro has a size of just 5x4x5 in (13x10x13 cm) and will keep your germinating seeds, your emerging taproots or growing seedlings safe and healthy.

Once your done building the propagator the spongepots are nicely soaked and ready to use. Put a single seed into each pre-made hole and cover it with some soil. There should be only the barest layer of soil covering the seed. Which side of the seed is up does not matter. The seedling will find its way to the surface while the root will grow in the other direction.

You just have to put the spongepots into the propagator and give it some time.
