When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.
The paper towel method also has its risk, as the fragile seedlings can be damaged during the potting process. The tiny roots can also get tangled in the paper towels, so make sure to move the seeds to potting soil before roots grow too long. Use your hands or tweezers to gently remove each seed from the paper towels and place them in a prepared growing medium.

The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.
When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.
When you place the germinated marijuana seed into the small dimple, make sure the root is facing downward. The root part needs to go deep into the hole as much as possible. The skin of the seed has to be at least .5 cm beneath the surface of the soil.
Finish things off by spraying the surface with a plant sprayer to make the soil moist. Seeds need to remain moist, so you should frequently check the dirt to make sure it has enough water for healthy plant growth.
Step 4 — Cover the Seed With a Thin Layer of Soil
Now that you have planted your weed seed, you are well on your way to growing a beautiful plant. When the time is right, you may want to transfer it outside. As stated previously, you will want to wait two weeks for the cannabis to become strong enough to withstand the elements.
Some people intend to grow cannabis plants indoors, and others want to do it outside. Below is a guide on how to plant weed seeds, which works for both methods. Follow these easy steps, and you will end up with quality cannabis plants.
Not to mention, hard seeds may need up to a week to begin sprouting due to a thicker coating. If they have not germinated after two weeks, then they are likely a dud.
