For one, peat pellets already have some nutrients in them, they retain water well, provide a dark place for germination, and you can just take the peat pellets once germination has occurred and plant the whole thing in soil, this protecting the root systems of the seeds.
The soil should have a pH level of roughly 6.0. Good potting soil can allow your seed to germinate and even provide it with enough nutrients for roughly the first 2 weeks of growth.
The next commonly used method for germinating weed seeds is by placing them directly in water. This method does usually work quite well, but it can also be a hit and miss depending on who you ask.
4. In Peat Pellets
Some people will begin to provide fluorescent or other types of lighting already at this stage, but technically this is not necessary until you see the plant sprouting from the dirt.
Place the potting soil in a small pot and then use your finger to make a little hole, about 1.5 cm or 0.6 inches deep. Take a seed, place it in the hole, and then cover it with soil, but don’t pack it down very hard. It should be somewhat loose.
However, do not do this more than once or twice. For instance, you can check on day 3, and then on day 4 after you have started the process.
Another commonly used method for marijuana seed germination is using paper towel or cotton pads. The benefit here is that germination process is very easy to keep an eye on, it tends to be fairly safe, and is very easy to get started. Now, be sure to pick good cotton pads or paper towels, ones that are smooth.
Often overlooked, it is all too easy to assume that the vegetative and flowering stages of cannabis growth are the most critical parts of the plant’s life cycle. However, with the chance of failure high unless you know what you’re doing, poor planning when it comes to germination can make or break your next grow. Giving your cannabis seeds the best possible start on their journey to bulging buds is a surefire way to encourage a healthy and robust plant.
THE ART OF GERMINATING CANNABIS SEEDS
Timescales can vary, as it all depends on how ideal your germination environment is (see the golden rules above). Even the worst grower could make a seed germinate, but it may take a few weeks and, of course, increases the risk of a weaker plant.
Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).
Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.
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.

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.
To germinate seeds indoors, use any of the methods described above. Within a few days, you’ll have popped seeds ready to transfer to a growing medium.
Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.
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.
The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.
