What are feminized seeds?

Feminized seeds have been bred to specifically produce female plants. These seeds are created with a process where they are sprayed with colloidal silver solution. This forces the female plant to produce pollen which is then used to pollinate another female plant. The resulting seeds have been bred with two female cannabis plants. This process ensures that the seeds will inherit female-only traits, resulting in plants that will flower and produce buds. Most growers prefer feminized seeds as they eliminate the uncertainty of growing male plants, which don't grow any smokable buds and can inadvertently pollinate females in your grow room, causing seeded flowers.

Are your feminized seeds guaranteed to grow female flowers?

At 420 Seeds, we collaborate with top-tier cannabis breeders, ensuring that our feminized seeds are of exceptional quality. While feminized seeds are designed to produce female plants, nature can sometimes be unpredictable. In the vast majority of cases, 99.9% to be precise, our feminized seeds will grow into female plants. However, on very rare occasions (around a 1 in 1000 chance), a male plant might develop.

What is the success rate of your feminized seeds?

We prioritize quality and customer satisfaction, which is why we only partner with breeders who provide germination guarantees. With this commitment to excellence, you can expect at least an 80% success rate for germination across every strain of our feminized seeds. This high success rate reflects the quality control and expert breeding techniques employed by our network of world-class cannabis breeders. When you choose our feminized seeds, you're selecting a product that is backed by assurance and expertise every time.

Advantages of growing feminized cannabis seeds

99.9% Guaranteed Female Flowers: Feminized seeds virtually guarantee that every plant will be female, meaning each one will produce THC rich buds used for you to smoke. This maximizes your growing potential and efficiency.

Less Risk: By growing feminized seeds, you massively reduce the risk of growing male plants. Male plants can lead to unwanted pollination, resulting in seeded, less potent buds.

More Yield: Because feminized seeds produce female plants, each plant contributes to the yield. Unlike regular seeds, where males take up space without yielding any smokable buds. Feminized seeds therefore allow you to make the most out of your entire grow space.

Easier to Grow: Feminized seeds simplify the growing process, especially for beginners. They eliminate the need for sexing plants and the risk of not spotting a male plant, making growing weed much easier.

Will my feminized seeds be fresh?

Yes, at 420 Seeds, we go to great lengths to ensure that our seeds are always fresh. Our feminized seeds are stored inside airtight, darkened boxes in commercial refrigerators at a consistent temperature of 6°C. We never hold large volumes of stock to guarantee a quick turnover.

What is the best way to store female seeds at home?

To store your feminized seeds at home, place them in an airtight container and keep it in a cool, dark, and dry spot, away from fluctuating temperatures. For storage beyond six months, keep them in a refrigerator between 6°C - °C.
