How to Make Feminized Seeds Step-by-Step: The Ultimate Guide 

As a marijuana grower, there’s one thing you dread – male plants. They can ruin your harvest and waste your time and money. But there’s a solution. Feminized seeds have become increasingly popular among growers and for good reason.

In this ultimate guide, we’ll teach you everything you need to know about making your own feminized seeds. From why they’re beneficial to the tools and materials you’ll need, the step-by-step process, tips for a successful harvest, and common mistakes to avoid, we’ve got you covered. So, let’s get started!

What Are Feminized Cannabis Seeds?

Feminized seeds are cannabis seeds that are genetically modified to produce only female plants. Female plants are the ones that produce the resinous buds that contain cannabinoids such as THC and CBD, which are sought after by consumers and growers.

These seeds are created by using specific techniques that induce a healthy female plant to produce male pollen sacs, then used to fertilize another female plant, resulting in seeds that have only female chromosomes.

What Are the Advantages of Using Them?

Feminized seeds offer a number of benefits to cannabis growers. Perhaps the most obvious advantage is that they practically guarantee a crop of female plants, which produce highly valued and sought-after buds.

With regular seeds, there’s always a chance that some of the plants will turn out to be male, which can be a major headache for growers. By using feminized seeds, you can streamline the growing process and avoid any unnecessary complications.

Another major benefit of feminized seeds is that they tend to produce more uniform plants. Since all of the seeds are guaranteed to be female, you won’t have to deal with the genetic variability that can arise from using regular seeds. This can make it easier to predict how your plants will grow and to plan accordingly. It can also be helpful if you’re looking to create a consistent product that meets specific standards.

In addition to these benefits, feminized seeds can be a good option for growers looking to save time and money. Since you won’t have to worry about sexing your plants or culling any males, you can focus your energy on growing and maintaining your crop. And since you’re guaranteed a high percentage of female marijuana plants, you’re more likely to get a good yield without having to plant as many seeds as possible.

Overall, feminized seeds offer a number of advantages that make them a compelling choice for many cannabis growers. Whether you’re a seasoned pro or a newcomer to the world of growing cannabis, they’re definitely worth considering if you’re looking to streamline your process and maximize your yield.

The Most Commonly Used Methods for Feminizing Cannabis Seeds?

There are different methods to make feminized cannabis seeds, but here are four of the most common ones:

1. How to Make Feminized Seeds with Gibberellic Acid Method

How to Make Feminized Seeds with Gibberellic Acid Method

Gibberellic acid (GA) is a plant hormone that stimulates growth and development. It can also induce male flowers on female plants, which can then be used to pollinate other female plants and produce feminized seeds.

This method is relatively simple and inexpensive, but it requires some care and attention to avoid unwanted results.

To use this method, you will need:

  • A female marijuana plant that is ready to harvest
  • A separate space or container to isolate the plant from other plants
  • A pair of scissors or tweezers to collect the pollen sacs
  • A paper bag or envelope to store the pollen sacs
  • A spray bottle with water to moisten the pollen sacs
  • A small paintbrush or cotton swab to apply the pollen to selected female flowers
  • A marker or label to identify the pollinated branches

Here are the steps to follow:

  1. Choose a healthy and stable female plant that you want to use as the mother plant. Ideally, it should have good genetics, high potency, and desirable traits. You will need two clones of this plant: one for spraying with GA and one for pollinating.
  2. Prepare a solution of GA by dissolving it in distilled water. The concentration of GA depends on the strain and the desired results, but a common range is between 100 and 200 ppm (parts per million). You can use a digital scale and a measuring cup to measure the exact amounts.
  3. Spray one of the clones with the GA solution every day, starting from the first week of flowering. Make sure to cover all the buds and leaves with the solution, but avoid spraying the soil or the stem. The GA will trigger the formation of male flowers on the female plant, which will take several weeks to develop.
  4. Wait until the male flowers are fully mature and start to release pollen. You can collect the pollen by gently shaking the plant over a sheet of paper or a plastic bag. Alternatively, you can leave the plant in the same grow space as the other clone and let nature do its work.
  5. Pollinate the other clone with the collected pollen or by placing it near the sprayed plant. You can use a small brush or a cotton swab to apply the pollen directly to the pistils of the female flowers. You can also spray some water on the buds after pollination to help them stick.
  6. Wait until the seeds are fully formed and ready to harvest. This can take anywhere from 6 to 10 weeks after pollination, depending on the strain and the conditions. The seeds will be dark brown or black and will have a hard shell. You can test their maturity by squeezing them gently between your fingers: if they crack, they are ready.
  7. Harvest the seeds by carefully removing them from the buds. You can use tweezers or your fingers to pick them out, but be gentle and avoid damaging them. You can also trim away any excess plant material from the seeds.
  8. Dry and cure the seeds by placing them in a paper bag or a glass jar and storing them in a cool and dark place for at least two weeks. This will allow them to mature and increase their germination rate. You can also label them with the strain name and date of harvest.
  9. Enjoy your feminized marijuana seeds! You can use them to grow more female plants of the same strain or cross them with other cannabis strains to create new hybrids. Remember to store them properly in a cool and dark place and use them within a year for optimal results.

Some pros of using GA are:

  • GA is relatively easy to obtain and use. It can be sprayed on selected branches or buds of female plants before the flowering stage.
  • GA can produce a large amount of pollen from a few male flowers, which can be used to pollinate many female plants.
  • It can allow growers to create their own feminized seeds from their favorite strains, without relying on commercial seed banks.

Some cons of using GA are:

  • It can be harmful to animals and humans if inhaled or ingested. It must be handled very carefully and wearing protective equipment.
  • It can affect the quality and potency of the buds that are sprayed with it. It can also cause unwanted mutations or deformities in the plants.
  • It can increase the risk of hermaphroditism in feminized seeds, especially if the plants are stressed or exposed to environmental changes. Hermaphrodites can produce both male and female flowers, which can ruin the crop by pollinating themselves or other plants.

2. How to Make Feminized Seeds with Colloidal Silver Method

How to Make Feminized Seeds with Colloidal Silver Method

Colloidal silver is a solution of silver particles suspended in water. It is commonly used as a dietary supplement or alternative medicine for various purposes. However, it can also be used to make feminized seeds.

CS works by inhibiting the production of ethylene, a hormone that regulates the sex of cannabis plants. By spraying it on a female plant during the flowering stage, you can prevent it from developing female flowers and make it grow male pollen sacs instead.

To use this method, you will need:

  • A female cannabis plant that is at least six weeks old and healthy
  • Colloidal silver solution (you can buy it online or make your own)
  • A spray bottle
  • A separate space to isolate the treated plant from other plants

Here are the steps to follow:

  1. Choose a branch of your female plant that you want to treat with CS. This branch will produce male pollen sacs, while the rest of the plant will remain female.
  2. Start spraying CS on the chosen branch daily as soon as you switch to 12/12 light cycle to induce flowering. Continue spraying until you see male pollen sacs forming on the branch. This may take 2-4 weeks depending on the strain and the concentration of colloidal silver.
  3. Once the pollen sacs are mature and start to open, collect the pollen in a small container. You can use a brush or a spoon to gently tap the sacs and release the pollen.
  4. Use the pollen to pollinate another female plant of your choice. You can pollinate the whole plant or just a branch. To do so, simply sprinkle some pollen on the female flowers using a brush or a spoon.
  5. Wait for about 6 – 10 weeks until the seeds are fully developed and ready to harvest. You can tell by looking at the calyxes (the swollen parts of the female flowers where the seeds form). They should be brown and hard, and you should be able to hear a rattling sound when you shake them.
  6. Harvest your feminized seeds and store them in a cool and dry place until you are ready to germinate them.

Some pros of using CS are:

  • It’s easy to obtain or make
  • It’s non-toxic and non-caustic
  • It has a high success rate in producing feminized seeds

Some cons of using CS are:

  • It can be expensive if bought online
  • It can damage your plant if used excessively or incorrectly
  • It can contaminate your buds if sprayed on them, making them unsafe to smoke

3. How to Make Feminized Seeds with STS Method

How to Make Feminized Seeds with STS Method, silver thiosulfate

Silver Thiosulfate is another solution that can be used to make feminized seeds. It is similar to colloidal silver in that it also inhibits ethylene production in cannabis plants, causing them to grow male pollen sacs instead of female flowers.

However, STS is more potent and effective than colloidal silver, as it contains two chemicals: sodium thiosulfate and silver nitrate. These chemicals react together to form silver-thiosulfate, which is then sprayed on the female plant.

To use this method, you will need:

  • A female plant that is at least six weeks old and healthy
  • Silver thiosulfate solution (you can buy it online or make your own)
  • A spray bottle
  • A separate space

The steps are as follows:

  1. Prepare the STS solution by mixing 0.5 grams of silver nitrate with 500 ml of distilled water in a glass container. This is the stock A solution. Then, mix 2.5 grams of sodium thiosulfate with 500 ml of distilled water in another glass container. This is the stock B solution. Store both solutions in a dark place until needed.
  2. When you are ready to spray your plant, mix equal parts of stock A and stock B solutions in a spray bottle. This is the working solution. Use it within 24 hours of mixing.
  3. Choose a branch or a bud site on your female plant that you want to turn into a male. Spray the working solution on the selected area until it is thoroughly wet. Do this once a day for 10 to 14 days, or until you see male pollen sacs forming.
  4. Isolate the sprayed plant from any other female plants to avoid accidental pollination. You can use a plastic bag or a tent to cover the treated area.
  5. Wait for the pollen sacs to mature and open. Collect the pollen in a small container and store it in a cool and dry place.
  6. Use the pollen to fertilize another female plant of the same strain or a different one. You can use a paintbrush or a cotton swab to apply the pollen to the pistils of the female flowers.
  7. Wait for the seeds to develop and harvest them when they are ripe. You can expect about 99% of the seeds to be female.

Some pros of using STS are:

  • It is relatively easy and cheap to make and use.
  • It does not affect the quality or potency of the buds or seeds.
  • It allows growers to create their own feminized seeds and strains.

Some cons of using STS are:

  • It is toxic and corrosive, so it requires safety precautions and proper disposal.
  • It can damage the sprayed plant if applied too much or too often.
  • It can cause unwanted pollination if not contained or isolated from other plants.

4. How to Make Feminized Seeds with Rodelization Method (RM)

How to Make Feminized Seeds with Rodelization Method (RM)

RM is a natural technique that some cannabis growers use to make feminized seeds. It involves letting a female plant flower beyond its normal harvest time until it develops male pollen sacs as a last resort to pollinate itself.

The pollen from these sacs can then be used to fertilize another female plant, resulting in seeds that are mostly female. However, this method has some drawbacks, such as low pollen production, low seed viability, and risk of hermaphroditism. Therefore, it is not recommended for beginners or commercial growers who want reliable and consistent results.

To use this method, you will need:

  • A female cannabis plant that is ready to harvest
  • A separate space or container to isolate the plant from other plants
  • A pair of scissors or tweezers to collect the pollen sacs
  • A paper bag or envelope to store the pollen sacs
  • A spray bottle with water to moisten the pollen sacs
  • A small paintbrush or cotton swab to apply the pollen to selected female flowers
  • A marker or label to identify the pollinated branches

The steps are as follows:

  1. Choose a healthy and vigorous female plant that has desirable traits such as potency, yield, and flavor. Avoid plants that are prone to hermaphroditism or have signs of stress or disease.
  2. Let the plant flower for 10 to 14 weeks, or until you see the first signs of male pollen sacs forming on the branches. These will look like small bananas or balls that are usually yellow or green in color.
  3. Carefully collect the pollen from the sacs using a small brush or a plastic bag. You can store the pollen in an airtight container in the freezer for up to six months.
  4. Pollinate another female plant of the same strain or a different one that you want to cross with. You can do this by gently brushing the pollen onto the pistils of the selected buds, or by placing a plastic bag over a branch and shaking it gently.
  5. Wait for the seeds to mature and harvest them when they are hard and dark in color. You can expect to get about 10 to 20 seeds per bud, depending on the size and density of the flowers.
  6. Store the seeds in a cool and dry place until you are ready to germinate them. You can test the germination rate by placing a few seeds on a damp paper towel and keeping them in a warm and dark place for a few days.

Some pros of using this method are:

  • It is simple and natural, requiring no chemicals or special equipment.
  • It preserves the genetic traits of the original female plant.
  • It can produce seeds that are more resistant to stress and environmental factors.

Some cons of using this method are:

  • It is unreliable and unpredictable, as not all plants will produce pollen sacs or viable seeds.
  • It can take a long time to wait for the plants to rodelize, delaying the harvest and increasing the risk of mold or pests.
  • It can result in lower-quality seeds, as the plants are stressed and overripe.

Tips for a Successful Harvest of Feminized Marijuana Seeds

To ensure a successful harvest, it is important to pay attention to a few key details:

1. Choose healthy and stable female plants: The quality and genetics of the female plants will determine the quality and genetics of the feminized seeds produced. It is advisable to choose plants that have desirable traits, such as potency, yield, flavor, aroma, resistance to pests and diseases, etc. It is also important to choose plants that are stable and not prone to hermaphroditism (the tendency to produce both male and female flowers), as this trait can be passed on to the offspring.

2. Isolate the male flowers: The male flowers produced by the female plants should be isolated from the rest of the crop, as they can pollinate any other female plants in the vicinity and create unwanted seeds. The male flowers can be cut off and placed in a paper bag or a container with a lid, or they can be left on the plant but covered with a mesh or a plastic bag. The pollen should be collected when the male flowers are fully mature and ready to open, which can be indicated by their color, shape, and texture.

3. Pollinate selectively: The pollen collected from the male flowers can be used to pollinate another female plant of the same strain or a different strain, depending on the desired outcome. However, it is advisable to pollinate only a few branches or buds of the female plant, rather than the whole plant, to preserve some seedless buds for consumption. The pollen can be applied with a small brush or a cotton swab, gently dabbing it on the pistils (the white hairs) of the selected buds. The pollinated buds should be marked with a tag or a string for identification.

4. Harvest and store the seeds properly: The feminize seeds will develop inside the pollinated buds, which will swell and turn brown as they mature. The seeds will be ready to harvest when they are hard, dark, and striped, usually after 6 to 10 weeks from pollination. The seeds can be extracted by breaking apart the buds and sifting them through a screen or a colander. The seeds should be dried in a cool and dark place for a few days, then stored in an airtight container in a refrigerator or a freezer until ready to use.

Common Mistakes to Avoid

By following the proper steps, feminized seeds can be successfully produced. However, as with any endeavor, there are some common mistakes that should be avoided to ensure the best results:

1. Using unhealthy or unstable plants: The plants that you use to make feminized seeds should be healthy, vigorous, and genetically stable. They should not have any signs of disease, pests, stress, or hermaphroditism. If you use unhealthy or hermaphrodite plants, you risk passing on these traits to the seeds and the offspring. You also risk producing low-quality seeds that may not germinate or grow well.

2. Using the wrong method to induce pollen production: There are different methods to induce a female plant to produce pollen. However, not all methods are equally effective or safe. Some methods may produce more pollen than others, but they may also cause more damage to the plant or leave harmful residues on the buds. Some methods may also affect the genetic stability of the plant and the seeds. You should research the pros and cons of each method and choose the one that suits your needs and preferences.

3. Applying too little of the pollen inducer: The amount of pollen inducer that you apply to the female plant can affect the quality and quantity of the pollen and the seeds. If you apply too little of the pollen inducer, you may not trigger enough pollen production and end up with few or no seeds. You should follow the instructions of the method that you use and monitor the plant’s response carefully.

4. Pollinating too early or too late: The timing of pollination is crucial for making feminized seeds. You should pollinate the female plant when it is in its peak flowering stage, usually around 2-3 weeks after switching to 12/12 light cycle. If you pollinate too early, you may not get enough viable seeds because the buds are not fully developed. If you pollinate too late, you may get immature seeds that will not germinate or grow properly. You should also avoid pollinating more than once, as this can reduce the quality and quantity of the seeds.

5. Not isolating the pollinated plant from other plants: Pollen can travel far and wide through air currents, insects, or human contact. If you do not isolate the pollinated plant from other plants in your grow room or outdoor garden, you may accidentally pollinate them as well and end up with unwanted seeds in your buds. You should keep the pollinated plant in a separate grow space or tent with good ventilation and filtration systems to prevent cross-pollination. You should also wear gloves and change your clothes when handling the pollinated plant to avoid transferring pollen to other plants or surfaces.
