There are several methods of germinating marijuana seeds. The most popular include the use of cotton wool (cotton buds) or rockwool. Like any other seed, marijuana seeds require water to germinate. Growers will usually pre-soak the seeds in cotton wool or in a damp environment, often in the dark, making sure they keep the seeds moist but not totally wet inside the cotton wool or rockwool. The seeds will usually take a few days or a week to begin to germinate. Growers then carefully transplant the seed after the tip of the root becomes visible. Carefully the seed and root is then put in soil or a hydroponic marijuana medium such as pearlite or rockwool to continue growing.
Below are some examples of marijuana seeds germinating or small seedlings that have just germinated. Growers will often then use a weak light like a fluoro to continue the process until the plant is ready for a more powerful light such as a metal halide.

The gardening season is booming in North America, and it’s high time to start some tiny seeds that can grow into potent plants, says Jorge Cervantes, veteran marijuana cultivator and author of “The Cannabis Encyclopedia”.
1) Soak seeds overnight in a glass of plain water. They may float on the surface at first but should sink to the bottom in a few minutes. Make sure seeds get good and wet so that water penetrates the outer shell and growth is activated. Do not let seeds soak for more than 24 hours, or they might get too wet, suffer oxygen deprivation and subsequently rot.

3) Drain the water from the dinner plate by tipping it to the side.
Jorge Cervantes shares his process for germinating cannabis seeds into healthy sprouts.
5) Check moisture level of towels several times a day, watering once or twice to keep them evenly moist. DO NOT LET THE TOWELS DRY OUT! Let excess water drain away freely. The paper or cloth towels will retain enough moisture to germinate the seeds in a few days. Each seed contains an adequate food supply for germination. Prevent fungal attacks by watering with a mild 2 percent bleach or organic fungicide solution.
The best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.
It’s essential to acquire high-quality cannabis seeds for germination, as these will go on to become high-quality cannabis plants. Seeds that are fresh-feeling or too green indicate that they haven’t reached full maturity, while pale-green, white, or very dark cannabis seeds may have trouble sprouting. However, it’s tricky to know the outcome of a popped seed, so trying may be worthwhile. If you’re not ready to pop your seeds yet, store them in a dark, cool place until it’s time for germination.

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.
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.
