If you are concerned that the seed cover is still on the leaf or concerned about how long the cannabis seed germination will still take, just remember the more warmth and moisture (not dampness) will accelerate the process for the Cannabis seeds to germinate and within 24 to 48 hours it should be completely out of its shell.

So now you know how long cannabis seeds germinate, what will happen after?

Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.

What is germination?

The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.

The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.

Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.

There is the risk here of damaging the roots during transfer, the risk of the seeds getting too much light, and of course, the risk of drowning. Some people do prefer this method, but we find it to be way too risky when compared to the others.

Moreover, the temperature for weed seed germination needs to remain at a steady 20 to 22 degrees Celsius, or about 68 to 72 degrees Fahrenheit.

Once the roots have sprouted, and are about 4 mm long, you then have to place them into soil. Do not place them into soil if they are shorter than 2 mm, and don’t wait until the roots are longer than 5 mm, as the roots will start to grow into the paper towels and cause you trouble.

3. In Water

This means that you can germinate your seed and start root growth, without having to transfer that fragile seed, with fragile roots, into potting soil. It minimizes the risk of having your weed seed’s root system being damaged.

Once you see the plant beginning to sprout out of the peat, you can then take the entire peat pellet and put it right into your potting soil. It’s a really easy method with a good success rate.

You don’t want to use overly porous materials here because once the roots start to come out of the seed, you run the risk of having them grow into the porous paper towel. The result here will be that the roots are hard to remove from the paper towel, potentially damaging them before you get the chance to transfer them into good potting soil.

Use a plant sprayer to moisten the soil, ensuring that water gets down to the seed. However, make sure that you don’t apply too much water, as you can easily drown a marijuana seed and kill it.
