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.
Place the soil in a small pot and use your finger or a pencil to push a small hole in the dirt, a bit more than half an inch deep. Insert the seed into the hole and bury it with soil. From this point on, don’t touch your seed. The young plant is fragile and knows how to position itself in the soil bed.
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.

To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.
How to germinate seeds in soil
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 paper towel method is also a common way cultivators pop their seeds. Some even use this method with cotton pads instead of paper towels, but the necessary steps are the same.
Plant a seed or two in each pot, making sure to keep the pots moist. Once the plants sprout, you can transplant them in their Jiffy Pot to a container or to a raised bed or garden plot.
And maybe you have been using trial and error but ended up thinking, “Why won’t my marijuana seeds germinate?”” Truth is, you’ve likely been making some mistakes without knowing it. You can increase your results, although some seeds inevitably will be duds. No one can attain 100% germination, but there is room for improvement regardless.
How long does it take to germinate marijuana seeds? Typically, it will take anywhere from a couple of days to up to a week to see your seeds start to turn into plants.
Germination simply means getting a seed to sprout a taproot, which will serve as its main root into the soil as it grows. For the best results, start with the best seeds you can afford to buy online or get from friends.
A clear plastic cover on the top keeps the warmth in. You can make one of these at home or purchase one inexpensively at your local nursery or online.
Some folks like to germinate their seeds in Jiffy Pots. You can buy these at nurseries and other places as little round disks.
Also known as seed starters, germination stations are like mini greenhouses. They include a tray filled with soil and a heat pad underneath to keep the soil warm.
Select the Right Seeds
Put a plate or other object under the bottom towel to prevent moisture damage and another over the top towel to keep the seeds in a dark space. When you see the white taproot emerge from your seeds, they will be ready to transplant. Make sure to plant them taproot down.
There are five basic germination methods that are popular. With any of these methods, remember that seeds will need adequate warmth, moisture, and air to germinate properly. Generally, cannabis seeds like a temperature of 70° F to 90° F for sprouting.
