Feminized cannabis seeds ensure growers only end up with female plants. There are 2 ways to grow feminized seeds at home.

Cannabis plants can grow out to be male or female. While male plants play an important role in the breeding process, end users are generally only interested in the buds from the female plant for their high THC content.

Unless they’re breeding, growers will generally also avoid male plants as they can easily pollinate females, greatly reducing the quality of their harvest. The creation of feminized seeds, however, forever changed the weed growing game, allowing growers to reliably grow female plants every time.

Luckily for you, you can now create your own feminized cannabis seeds at home without having to buy them from a seed bank. There are 2 ways to grow feminized seeds at home:


This is the more natural way to create female cannabis seeds. It basically involves forcing your female plants into becoming hermaphrodites by refusing to harvest their buds.

Hermaphroditism is a natural feature of the cannabis plant, and female plants usually become hermaphrodites when they’re growing in particularly tough conditions. As the plant senses that it is nearing the end of its life cycle, it will pollinate itself in a final attempt to reproduce.

The same happens if female plants are allowed to mature long enough. Again, as the plant reaches the end of its life cycle and senses that it hasn’t been pollinated, it will auto pollinate. Hence, by not harvesting your female plants you can essentially trick them into becoming hermaphrodites. And, as long as they haven’t come into contact with male pollen, you can rest assured the seeds you end up with will be feminized.

While rodelization is the most natural way to produce female seeds, it isn’t very reliable. This is because, even though you refuse to harvest your plants, it isn’t guaranteed that your plants will pollinate themselves.

Hermaphroditism is partially genetic and hence the success of the rodelization method depends on the genetics of your plants. Some plants will create seeds more easily than others.



Colloidal silver is a dietary supplement marketed for having a variety of health benefits. It is a liquid containing tiny silver particles and, while marketed as a cure-all, is highly debated regarding its medicinal benefits and/or risks.

Regardless of whether colloidal silver is really what it’s marketed to be, one thing is for sure; it works wonders on female cannabis plants. Simply spray the solution on your cannabis plants in the early flowering stage and you’ll eventually end up with hermaphrodite plants full of female pollen.

Make sure to start early during the flowering phase, spraying any bud sites with colloidal silver solution on a daily basis. Eventually, you’ll notice that the plants that have been sprayed develop male flowers, recognizable by their iconic ball shape.

As these buds develop they’ll produce pollen just like regular hermaphrodite plants. However, the pollen will be completely female. You can then harvest this pollen to pollinate another flowering female plants like normal.

Why plants react this way to colloidal silver isn’t clear, it just works. Something in the colloidal silver solution essentially creates hermaphrodite plants without having rely on the rodelization method.

It is important to note that buds that have been sprayed with colloidal silver should NEVER be smoked. The seeds, however, are perfectly safe and can be planted just like regular feminized seeds.

If you’re worried about the legitimacy of this tip, don’t be. In fact, many seed banks use this method to produce their own line of feminized seeds. However, note that there are some downsides to using colloidal silver to produce feminized seeds as well.

Most notably, the technique isn’t natural and involves spraying your plants with a unnatural solution which renders your buds unusable. Some growers will bypass this, spraying only parts of the plants with colloidal silver so as to produce both hermaphrodite and female buds.

It is hard to tell whether this is safe. If you choose to do this, just remember you’re doing so at your own risk.
