Feminized cannabis seeds are cannabis seeds that have been bred to contain no male chromosomes, thus ensuring that every plant they produce grows up to be a female. This is done by a process called “feminization” which basically involves treating regular cannabis seeds with a hormone that causes them to produce only female plants.

Feminized seeds are popular with growers who don’t want to have to deal with males, as they can save a lot of time and effort by ensuring that every plant they grow is guaranteed to be high-yielding and THC-rich. This guide will teach you how to feminize your own cannabis seeds at home using the silver thiosulfate method.

What You’ll Need:
-Cannabis seeds (regular, not feminized)
-Silver thiosulfate (STS) solution
-Distilled water
-Eye dropper
-Glass jar with lid
-Paper towels

What are Feminized Cannabis Seeds?

Feminized cannabis seeds are the genetically modified offspring of two female cannabis plants. The pollen produced by the male plant is altered to create female plants that only produce female gametes (sex cells). This means that all of the seeds produced by a feminized cannabis plant will be female.

Feminization is achieved through a variety of methods, the most common of which is treating the male plant with silver thiosulfate (STS). This solution prevents the male plant from producing viable pollen, which in turn forces the female plant to produce male flowers that contain no genetic material. These flowers pollinate the females, and the resulting seeds are feminized.

Other methods used to create feminized seeds include using chemicals such as gibberellic acid or colloidal silver, or exposing the plants to stressors such as extreme heat or light. However, these methods are less reliable and can often produce hermaphrodite plants (plants that contain both male and female reproductive organs).

Hermaphrodite plants are not ideal for grow operations because they can pollinate themselves and other nearby plants, leading to seedy buds. For this reason, it is best to purchase feminized seeds from a reputable source.

How to Make Feminized Cannabis Seeds

You can make your own feminized cannabis seeds at home with just a few supplies. You will need to purchase a female cannabis plant, some silver thiosulfate solution, and some plastic wrap. Follow the instructions below and you will have your own feminized cannabis seeds in no time!

The Rodelization Method

The Rodelization method is the most common and popular way of making feminized seeds. It is also the easiest method with the least amount of chance for error. You can do this by simply letting your female cannabis plants go longer than normal before you harvest them.

What happens is that as the end of a female plant’s life cycle approaches, it will begin to produce pollen in order to create new seeds. If you allow this process to happen and do not remove the male pollen sacs that appear, some of it will inevitably end up landing on the female flowers.

When this happens, the flowers will be pollinated and will start to produce seeds. However, because they have been pollinated by another female, all of these seeds will be feminized!

The Colloidal Silver Method

The colloidal silver method is a pretty popular way to make feminized cannabis seeds. It’s also one of the cheaper methods, since all you need is some silver and distilled water.

The basic idea is that you create a silver solution and then use that solution to spray your female plants. The silver will interfere with the plant’s hormone production, causing it to produce male flowers. Once the flowers have been pollinated, the resulting seeds will be feminized.

You can buy colloidal silver solutions online or at some health food stores. Or, you can make your own by suspending silver wires in distilled water using a battery and some alligator clips.

Once you have your solution, just spray it on your plants once a week for three weeks, being careful to avoid the buds themselves. After three weeks, you can stop spraying and wait for the flowers to appear.

The Gibberellic Acid Method

The Gibberellic Acid method is one of the most common ways to make feminized cannabis seeds. It involves using a chemical called gibberellic acid, which is found in some plant growth regulators. When gibberellic acid is applied to female cannabis plants, it causes them to produce male flowers. These flowers will then produce pollen that can be used to fertilize other female plants, resulting in the creation of feminized seeds.

To use this method, you will need to purchase a gibberellic acid solution from a grow shop or online retailer. Once you have the solution, mix it according to the instructions on the package and apply it to the leaves of your female cannabis plants. Be sure to wear gloves and protective clothing when applying the solution, as it can be harmful if it comes into contact with your skin.

The gibberellic acid method is an effective way to create feminized seeds, but it can be damaging to your plants if not used properly. If you decide to use this method, be sure to follow the instructions carefully and only apply the solution as directed.


Now that you understand how to make feminized cannabis seeds, you can experiment with different techniques to find the one that works best for you. Remember to start with healthy plants, and don’t be afraid to ask for help if you need it. With a little practice, you’ll be a pro in no time!
