Many people choose to use peat pellets, starter cubes, and seedling plugs when germinating weed seeds. You can buy starter cubes and seedling plugs if you are starting out. Many of them consist of micronutrients to promote root growth. Each one already has a hole made for a single seed.
Some general tips for germinating cannabis seeds include:
Rockwool comes with a few advantages. One is that the cubes are cheap and easy to find. They can hold plenty of moisture, and you do not have to worry about mold. Not to mention, they are convenient to use.
Wet Paper Towels (recommended)
A disadvantage of soaking the seeds in a cup is that too much water can be damaging. The excess amount can rot the newly emerged root. Those that have not sprouted yet will drown if left soaking for too long.
Here is an explanation of each germination method.
Keep things dark but turn on your grow lights at the first sign of sprouting. Once the seeds have sprouted, you will need to provide plenty of light. Preferably, they should receive it 18 hours a day.
Now that you know how to germinate cannabis seeds, the next step is to plant the sprouted seedlings. You do not need much in terms of planting. For example, you will want a large enough pot and a plant sprayer. If you used incandescent bulbs to keep the seeds warm, switch them out for actual growing lights.
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.
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.
So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.

Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.
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.
Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.
