The process of growing your cannabis plants begins with the initial step of germinating cannabis seeds. Whether you’re an experienced cultivator or new to the world of gardening, this process plays a vital role in ensuring the health and vitality of your plants. In this article, we will provide you with a step-by-step guide on how to germinate cannabis seeds. So grab your gardening gloves, and let’s begin!

Understanding Germination

Before delving into the specifics of cannabis seeds, it’s important to grasp the concept of germination itself. Germination refers to the process through which a seed commences its journey towards becoming a plant. Proper germination is essential for facilitating root formation and enabling growth.

The Soaking Method

Amongst the common techniques for germinating cannabis seeds, the soaking method stands out as one of the most popular approaches. Here’s how it works:

  1. Prepare a glass filled with filtered water: Opting for filtered water ensures that no impurities hinder the germination process.
  2. Carefully place your cannabis seeds in the water: Gently position each seed into the water. It’s crucial not to overcrowd the glass as each seed requires space for soaking and development.

Here is an alternative way to approach the process:

  1. Soak the seeds: Allow the seeds to soak in water for 12 to 24 hours, giving them time to absorb sufficient water for germination.
  1. Check sinking vs. floating seeds: After the soaking period, some of the seeds may sink while others may still float on the water’s surface. It is more likely that the sinking seeds are more viable for germination compared to those that are floating.
  1. Transfer soaked seeds: Carefully move all the sunken seeds onto a moist paper towel or a cotton pad.

The Paper Towel Method

Another commonly used technique involves using paper towels or napkins:

  1. Wet the paper towel or napkin: Take a paper towel or napkin and thoroughly saturate it with water, ensuring that it is damp but not dripping.
  1. Place the seeds on the towel: Gently position your seeds onto the towel, leaving space between each seed.
  1. Cover with another paper towel: Place another wet paper towel over the top of your seeds, making sure they are completely covered.
  1. Protect with encapsulation: Fold or wrap the paper towels containing the seeds to provide protection and create a moist environment.
  1. Warmth and darkness: To ensure the growth of your sprouted cannabis seeds, you have two options. You can either continue their development using soil cultivation or transfer them to a suitable medium, like peat pellets.

When transplanting germinated cannabis seeds into soil indoors, make sure to plant them. Create a quarter-inch hole and place the seedling inside at room temperature. If you’re planting them outdoors during months with risks of frost (probability below 5%), bury them about half an inch deep in loose topsoil. The warmth from sunlight exposure will create growing conditions.

Shipping Cannabis Seeds

Shipping your seeds is another option if you prioritize cost-effectiveness and space efficiency for germination:

  1. Prepare peat pellets by saturating them and then squeezing out any excess water.
  2. Take a dish or plate that has holes designed for this purpose and place the wet peat pellets on it. When these pellets fully expand, they will occupy one plug compartment, allowing for strong root establishment after each drying cycle (you can set up four growing schedules).
  3. Place each sprouted seed in its peat pellet, making sure to position them from the walls towards the areas as needed based on humidity levels.
  4. Use a plastic dome and wrap the container with cling film to create a moist environment that aids germination by retaining moisture.

Germination Care

Once your cannabis seeds have successfully sprouted, it’s important to give them care and attention for seedling development. Here are some key points to consider:

  1. Temperature: Maintain a temperature range of 70°F to 85°F (21°C to 29°C) to promote root growth and prevent any stress on the seedlings.
  1. Lighting: Ensure your germinated seeds receive light. If natural sunlight is not available, consider using specialized grow lights designed for plants.
  1. Watering: Keep the soil or peat pellets moist, but avoid saturating them. Overwatering can cause the roots to rot, so it’s crucial to find the right balance. Also, make sure that your germinating seeds have airflow around them, but avoid exposing them to strong gusts of wind.


Beginning the germination process for cannabis seeds is a key step toward growing your own cannabis plants. Whether you opt for soaking or the paper towel method, following these steps will increase the success rate of germination and give your plants a head start. Remember to provide care by regulating temperature, light exposure, and water levels and ensuring adequate ventilation throughout the process. So roll up your sleeves and get ready for a successful journey of cultivation! Happy growing!
