If you’re a cannabis grower, you know that female plants produce the coveted buds while male plants are usually removed from gardens. Will seeds from a female plant be female?
If you have a successful crop of female plants, it’s natural to wonder whether their low-THC seeds will also be female.
The answer is not straightforward as several factors can influence sex determination in cannabis plants. To understand why some seeds from a female plant may not necessarily be female themselves, it’s essential to delve into the genetics of cannabis.
Unlike humans and animals where sex is determined by chromosomes (XX for females and XY for males), sex determination in cannabis is more complex and influenced by several genetic and environmental factors.
While the precise mechanism is still unclear, research has shown that genes on different parts of the plant’s genome interact with each other to determine sex.
These genes can be activated or suppressed by various environmental cues like light cycles or temperature changes during specific stages of development.
Let’s talk more about the probabilities of a female plant producing more bud-bearing beauties.
- Seeds from a female cannabis plant can produce male, female, or hermaphroditic plants depending on how they were fertilized.
- Environmental cues such as light cycles, temperature changes, and stress can activate or suppress genes that determine sex in cannabis plants.
- Factors like nutrient availability, soil pH levels, pests or diseases, and genetics can also affect sex determination in cannabis plants.
- High-quality feminized seeds from reputable breeders or seed banks have been specifically bred to produce only female plants, but even these seeds may produce male offspring due to genetic variations or environmental stressors during growth.
Understanding the genetics of cannabis
So, you want to understand the genetics of cannabis and figure out if seeds from a female plant will always produce female plants, right?
Well, let’s break it down for you. Cannabis is a dioecious plant, which means it has separate male and female reproductive organs. The plant can either be male or female, but some strains are hermaphroditic, meaning they have both male and female reproductive organs.
The gender of the plant is determined by its genetics. A cannabis plant with two X chromosomes will be female, while a plant with one X chromosome and one Y chromosome will be male.
When a female plant is pollinated by a male, the resulting seeds can have either XX (female) or XY (male) chromosomes, depending on whether the pollen was carrying an X or Y chromosome.
Therefore, seeds from a female plant can produce both male and female plants, as well as hermaphroditic ones, depending on how they were fertilized.
Factors that influence sex determination
One surprising fact is that environmental factors such as temperature and light can play a significant role in determining the sex of a plant.
Cannabis plants are typically dioecious, meaning they have separate male and female individuals. There are also hermaphroditic plants which possess both male and female reproductive organs.
The presence of either sex is determined by the chromosomes present in each seed, but this process can be influenced by certain conditions.
Factors such as temperature and light cycles during the vegetative stage can influence whether a plant develops as male or female. Here are some other factors that can affect sex determination:
- Nutrient availability
- Soil pH levels
- Stress caused by pests or disease
It’s important to note that while these factors may increase the likelihood of producing one sex over another, there is no guarantee that seeds from a female plant will always produce female offspring.
Understanding these influences on sex determination can help growers manipulate their growing environment to achieve desired results.
The probability of female seeds
It’s fascinating to consider the likelihood of producing a bountiful garden full of lush, beautiful plants with delicate, fragrant flowers. When it comes to producing cannabis buds, one of the most important factors is ensuring that you have female plants.
Are regular seeds better than feminized ones? Growers looking to experiment may think so.
Anyone looking for juicy, bud-bearing plants should pick feminized seeds. Regular seeds contain males and females which are difficult to grow together unless you want them to propagate.
The good news is that seeds from a female plant are more likely to produce female offspring. The probability of producing female seeds depends on various factors, such as genetics, environment, and cultivation techniques.
First and foremost, it’s important to choose high-quality feminized seeds from reputable breeders or seed banks. These seeds have been specifically bred to produce only female plants.
Additionally, providing ideal growing conditions such as proper lighting and nutrients can increase the chances of producing more females.
Bear in mind that there is still a small chance (around 5%) that even feminized seeds may produce male offspring due to genetic variations or environmental stressors during growth.
Tips for cultivating female plants
To ensure you have a garden full of flourishing, vibrant female cannabis plants, try implementing these tips for cultivating the most luscious and bountiful buds possible.
First off, make sure to start with high-quality feminized seeds from a reputable source. This will give you the best chance of producing an all-female crop without having to worry about any males popping up and pollinating your precious females.
Next, it’s important to provide your female plants with optimal growing conditions. Keep the temperature between 68–77°F during the day and no lower than 60°F at night.
Make sure they receive plenty of light—ideally 18 hours per day during vegetative growth and 12 hours per day during flowering.
Additionally, use a high-quality nutrient solution specifically designed for cannabis plants and monitor pH levels regularly to ensure proper absorption of nutrients.
With these tips in mind, you’ll be well on your way to cultivating thriving female cannabis plants that produce an abundance of potent buds.

Frequently asked questions
Can male plants produce female seeds?
No, male plants cannot produce female seeds. The sex of a seed is determined by its genetics and whether it was pollinated by male or female pollen. Only female plants can produce female seeds.
How do environmental factors affect the sex of cannabis plants?
As a cannabis grower, you may wonder how environmental factors influence the sex of your plants. Factors like temperature, light, and nutrients can affect the expression of sex genes in unpredictable ways.
Understanding these factors can help you manipulate plant sex to your advantage.
Is it possible to determine the sex of a cannabis plant before it starts flowering?
Determining the sex of a cannabis plant before flowering is possible through genetic testing or by examining pre-flowers. Look for small growths at nodes that will develop into either male or female reproductive organs.
Can feminized seeds produce male plants?
Feminized seeds are created by forcing a female plant to produce male pollen, which is used to fertilize another female. While rare, there is still a chance that these seeds can produce male plants.
What are the benefits of cultivating male cannabis plants?
Cultivating male cannabis plants can benefit breeding programs by providing pollen to fertilize female plants. They also produce terpenes and other compounds useful in the extraction processes. Think of them as the wingmen to your female plant’s main attraction.
So, there you have it. You now know that seeds from a female cannabis plant may not always produce female plants. The genetics of cannabis are complex and influenced by various factors, including environmental stressors and genetic mutations.
While the probability of getting female seeds is higher when using a feminized seed or cloning a female plant, it’s important to keep in mind that there is still a chance for male or hermaphroditic plants to develop.
However, with proper cultivation techniques and careful monitoring, cultivating female plants can be achieved.
Remember to pay attention to the sex of your plants during the vegetative stage and take action if any male or hermaphroditic traits are detected. With patience and diligence, you can increase your chances of producing a successful crop of high-quality female cannabis plants.
