Can Feminized Seeds Turn Hermie?

As a cannabis cultivator, you may have heard about feminized seeds and their potential to turn hermaphrodite, or ‘hermie’. This is a topic that has sparked much debate within the cannabis community. So, let’s delve into the science behind it and explore whether feminized seeds can indeed turn hermie.

Understanding Feminized Seeds

Feminized seeds are a type of cannabis seed that is bred to produce only female plants. They are created by inducing a female plant to produce pollen, which is then used to fertilize another female. The resulting seeds lack male chromosomes, so they produce only female plants.

The Hermaphrodite Phenomenon

A hermaphrodite, or ‘hermie’, is a cannabis plant that develops both male and female flowers. This can occur as a result of genetic instability or environmental stress. When a female plant turns hermie, it can pollinate itself and other plants, leading to seeds in your bud.

Can Feminized Seeds Turn Hermie?

The short answer is yes, feminized seeds can turn hermie. However, the likelihood of this happening is largely dependent on the quality of the seeds and the conditions in which they are grown.

  • Seed Quality: High-quality feminized seeds are less likely to turn hermie. This is because they are produced by reputable breeders who use stable mother plants and rigorous breeding techniques to ensure genetic stability.
  • Growing Conditions: Even the best seeds can turn hermie if they are subjected to environmental stress. This can include factors such as inconsistent lighting, extreme temperatures, over or under-watering, and nutrient deficiencies.

Preventing Hermaphroditism in Feminized Seeds

While it’s not possible to completely eliminate the risk of feminized seeds turning hermie, there are steps you can take to minimize this risk.

  • Choose Quality Seeds: Always buy your seeds from a reputable breeder. This will ensure that you’re starting with genetically stable seeds.
  • Provide Optimal Growing Conditions: Maintain consistent lighting, temperature, and humidity levels. Avoid over or under-watering and provide your plants with the right nutrients.
  • Monitor Your Plants: Regularly check your plants for signs of stress or hermaphroditism. If you spot a hermie, remove it from your grow room immediately to prevent it from pollinating your other plants.


In conclusion, while feminized seeds can turn hermie, the likelihood of this happening is largely dependent on the quality of the seeds and the conditions in which they are grown. By choosing high-quality seeds and providing optimal growing conditions, you can significantly reduce the risk of your feminized seeds turning hermie. Remember, the key to successful cannabis cultivation is knowledge, patience, and attention to detail.
