Germinating seeds and caring for seedlings

Germinating cannabis seeds and caring for seedlings is an important first step in growing cannabis. It is a crucial moment in the plant life cycle as it lays the foundation for healthy growth and maximum yield. In this blog we will discuss how to germinate cannabis seeds and how to care for seedlings to get the best possible start.

Step 1: Germinate Seeds

Before you can start growing cannabis, you need to germinate the seeds. Germinating cannabis seeds is actually quite easy. Here are two of the most common techniques.

The coffee filter technique is a popular method of germinating cannabis seeds. Here's how it works:

  • Take a coffee filter and fold it in half. Moisten the coffee filter with water and squeeze out the excess water. Place the moistened coffee filter on a flat surface.
  • Place the seeds on one of the halves of the coffee filter. Make sure the seeds are evenly spaced so they don't get tangled up during germination.
  • Fold the coffee filter so that the seeds are between the two halves of the coffee filter. Place the coffee filter in a plastic bag and close the bag.
  • Place the pouch in a warm and dark place, such as a cupboard or drawer. Check the coffee filter regularly and moisten it if necessary to ensure that the seeds remain moist. After a few days, the seeds should germinate and show small roots.

The coffee filter technique has a number of advantages over other germination methods. It is a simple and inexpensive method that takes up little space. In addition, the coffee filter ensures that the seeds remain moist in an even manner, which increases the chance of germination. The plastic bag ensures that the humidity remains high, which also contributes to successful germination.

Once the seeds have germinated, they can be transferred to soil or a growing medium of your choice. Be sure to treat the seedlings with care and attention, providing the right environment and conditions for the plants to grow healthily.

Technique 2

Step 1: Fill a glass with warm water and soak the seeds for about 24 hours. This will help speed up the germination process.

Step 2: Remove the seeds from the water and place them on a plate. Cover the seeds with a damp paper towel, making sure no seeds are touching.

Step 3: Place the plate with the seeds in a warm and dark place, for example in a kitchen cabinet or grow tent. Keep the paper towel damp, but not too wet.

Step 4: Check the seeds after about 2-3 days. The seeds should now sprout and have a small root sticking out.

Step 5: Once the seeds have germinated, you can plant them in your growing medium of choice.

Step 2: Care for seedlings

Now that your cannabis seeds have germinated, it's time to care for seedlings. Seedlings are the young plants that have emerged from the seeds and are not yet fully grown. Here are some important things to keep in mind when caring for seedlings:

  1. Lighting: Seedlings need a lot of light to grow. When growing indoors, make sure you give them enough light. LED lamps are the best choice here.

  2. Temperature: seedlings need a constant temperature between 20 and 25 degrees Celsius to grow optimally.

  3. Water and nutrition: seedlings don't need a lot of water, but you do need to water them regularly. Preferably use water at room temperature. You don't have to give them extra food in the beginning.

  4. Humidity: Seedlings need high humidity to grow. Keep the humidity between 70% and 80%.

  5. Growing medium: choose the right growing medium for your seedlings. The most commonly used growing mediums are soil, coconut fiber or a hydroponic system.


Germinating cannabis seeds and caring for seedlings is an important part of caring for seedlings is providing the right environment and conditions. Here are some tips:

  • Light: Young seedlings need a lot of light to grow, so it's important to place them near a south-facing window or grow them under artificial light.
  • Temperature: seedlings thrive best in temperatures between 20-25 degrees Celsius. Make sure the ambient temperature remains stable and avoid drafts.
  • Water: Seedlings need little water, but it is important to keep the soil moist. Water when the top layer of the soil feels dry to the touch.
  • Feeding: young seedlings do not need much feeding yet. Wait until they have developed at least two sets of true leaves before feeding.

As the seedlings grow they should be transferred to larger pots and trained to grow upright. This can be done by supporting them with sticks or mesh. Be careful not to damage the plant while training.

Caring for seedlings can be a challenging process, but it can also be very rewarding. With proper care and attention, seedlings can grow into healthy and strong cannabis plants that produce bountiful harvests. Be patient and keep experimenting with different techniques and methods to find what works best for you and your plants.
