How to Make Your Own Cannabis Seeds

Cannabis seeds are an essential part of growing cannabis plants. Whether you’re a seasoned cannabis grower or just getting started, knowing how to make your own cannabis seeds can save you money and provide a greater level of control over your cannabis strains. In this section, we will discuss the basics of making your own cannabis seeds.

The Importance of Genetics

Before diving into how to make cannabis seeds, it’s important to understand the importance of genetics. Genetics refers to the traits and characteristics of a cannabis strain, such as its flavor, aroma, potency, and growth pattern. The genetics of a strain play a critical role in determining its quality and yield, so it’s essential to start with high-quality genetics when making your own cannabis seeds.

Choosing Parent Plants

The first step in making your own cannabis seeds is choosing the parent plants. This is an important decision that will determine the genetics of your offspring plants. When selecting parent plants, it’s important to choose plants with desirable traits that you want to pass on to your offspring. This could include factors like potency, yield, flavor, or growth pattern.

Once you have selected your parent plants, you will need to isolate them from other plants to prevent cross-pollination. This can be done by growing the plants in separate rooms or tents or by using isolation bags or screens to cover the plants.


Once you have isolated your parent plants, it’s time to begin the pollination process. This involves transferring pollen from the male plant to the female plant. The male plant will produce pollen sacs that contain the pollen, which can be collected and stored until it’s time to pollinate the female plant.

When pollinating the female plant, it’s important to ensure that the pollen is evenly distributed over the entire plant. This can be done by brushing the pollen onto the female plant or by placing the male plant in close proximity to the female plant to allow for natural pollination.

Seed Production and Harvest

After pollination, the female plant will begin to produce seeds. The seeds will develop over several weeks, and you can monitor their progress by observing the size and color of the seeds.

Once the seeds are fully matured, they can be harvested by cutting the seed pods from the plant and allowing them to dry. The seeds can then be stored in a cool, dry place until you’re ready to use them.

Here’s a step-by-step guide on how to make your own cannabis seeds:

  1. Choose your parent plants: The first step in making your own cannabis seeds is choosing the parent plants. You’ll want to select two plants that have the traits you want to pass down to their offspring. Make sure the plants are healthy and free of pests or disease.
  2. Pollinate the female plant: Once you’ve selected your parent plants, you’ll need to pollinate the female plant. To do this, you’ll need to collect pollen from the male plant and apply it to the female plant. You can collect the pollen by gently shaking the male plant’s flowers over a piece of paper or by using a small paintbrush to collect the pollen and transfer it to the female plant.
  3. Wait for the seeds to develop: After pollinating the female plant, you’ll need to wait for the seeds to develop. This can take several weeks, so be patient. Once the seeds are mature, you can harvest them.
  4. Store the seeds: Once you’ve harvested the seeds, you’ll need to store them properly to ensure they remain viable. Store the seeds in a cool, dry place, and make sure they are protected from light and moisture.
  5. Grow your new plants: Once you have your new seeds, you can start growing your new plants. Make sure to follow best practices for growing cannabis, such as using high-quality soil and providing adequate light and water.

Making your own cannabis seeds can be a fun and rewarding experience. By creating your own strains, you can tailor your plants to your specific preferences and even potentially create new strains that could become popular in the cannabis industry.

Harvesting and Storing Your Cannabis Seeds

Once you have successfully pollinated your female plants, it’s time to harvest and store your cannabis seeds. Here are the steps to follow:

  1. Wait for the seeds to mature: Cannabis seeds will take anywhere from 2-6 weeks to fully mature after pollination. You’ll know they’re ready to harvest when they turn dark brown or black and start to develop a hard, protective outer shell.
  2. Harvest your seeds: To harvest your cannabis seeds, gently pluck them from the plant with tweezers or your fingers. Be careful not to damage them, as this can affect their viability.
  3. Dry your seeds: Once you have harvested your seeds, you’ll need to dry them out. Spread them out in a single layer on a paper towel or plate and let them dry for a week or two. They should be completely dry and brittle before you move on to the next step.
  4. Store your seeds: To store your cannabis seeds, place them in an airtight container, such as a glass jar or plastic bag. Store them in a cool, dry place, away from light and moisture. You can also add a silica gel packet to help absorb any excess moisture.

With proper storage, your cannabis seeds can remain viable for years. When you’re ready to use them, simply plant them as you would any other seed.


Making your own cannabis seeds is a fun and rewarding process that allows you to have complete control over the genetics of your plants. By following these basic steps, you can create your own unique strains that are perfectly suited to your needs and preferences. Just remember to be patient, take your time, and enjoy the process. With a little bit of practice, you’ll be a pro at creating your own cannabis seeds in no time.
