Female Cannabis Plants Producing Seeds Without Male Plants

Cannabis crops can do some funky things at times, and one of the rare and intriguing occurrences is when female cannabis plants produce seeds without male plants involved. This phenomenon is considered problematic for growers, as it can impact the harvest’s quality, potency, and yield. This article will delve into cannabis plant reproduction, explore the…

Female Cannabis Plants Producing Seeds Without Male Plants

How Cannabis Plants Reproduce

Cannabis is a dioecious plant, meaning there are separate male and female plants.

Males produce pollen, while females produce flowers (or buds).

For cannabis to produce seeds, female flowers must be pollinated by males, which can happen through wind, insects, or human intervention.

How Cannabis Plants Reproduce

Pollination decreases yields and potency, so growers often aim to prevent it in their crops.

The Role of Male Plants

Male cannabis plants play a vital role in reproduction, as they produce pollen necessary for fertilizing female plants.

Pollen from male plants is carried by wind, insects, or human intervention to female plants, where it fertilizes the flowers and leads to seed production.

The Role of Female Plants

Female cannabis plants are responsible for producing flowers and seeds.

The flowers, also known as buds, contain high levels of cannabinoids like THC and CBD, which are the primary compounds responsible for the plant’s therapeutic and psychoactive effects.

Female plants only produce seeds when male plants pollinate their flowers.

Reasons for Females Producing Seeds Without Males

There are a few possible reasons for female cannabis plants producing seeds without male plants, including self-pollination, hermaphroditism, and stress-induced pollination.


In rare cases, female cannabis plants can self-pollinate, where a single plant produces both male and female flowers.

That can result in seed production without male plants.

However, self-pollination is only one of the common causes of female plants producing seeds without males.


Hermaphroditism is when a cannabis plant exhibits both male and female reproductive organs.

That can lead to a female plant producing seeds without male plants, as the male flowers on the hermaphrodite plant can pollinate the female flowers.


Genetic disposition or environmental stress factors, such as light poisoning or negative stressors, can cause hermaphroditism in cannabis plants.

Stress-Induced Pollination

Stress factors can trigger seed production in female cannabis plants without male plants.

Examples of stressors that can cause this include over or under-watering, incorrect pH levels, lack of nutrients, extreme temperatures, poor air circulation, light stress, and lack of root space.

Heavy stress training can also lead to seed production in female plants.

Consequences of Female Plants Producing Seeds

When female cannabis plants produce seeds without male plants, there are several consequences for the quality, potency, and yield of the harvest:

  • Decreased Yields: Seed production takes energy away from flower and trichome formation, leading to lower overall yields.
  • Decreased Potency: As energy is directed towards seed production, the potency of the buds decreases due to reduced cannabinoid content.
  • Lower Quality Buds: Seeded buds are generally lower quality, as they are less visually appealing and more difficult to process for consumption or extraction.

Preventing Unwanted Seed Production

To prevent unwanted seed production in female cannabis plants, consider the following tips and best practices:

  • Proper Cultivation Techniques: Ensure that you provide your plants with the right water, nutrients, and light balance to minimize stress factors that can lead to seed production.
  • Environmental Management: Maintain optimal temperature, humidity, and air circulation to create a stable environment that reduces plant stress.
  • Early Detection of Male Plants or Hermaphrodite Traits: Regularly inspect your plants for signs of male flowers or hermaphroditism. Remove any affected plants from your grow space as soon as possible.
  • Use Feminized Seeds: Feminized seeds produce only female plants, which minimizes the risk of accidental pollination by misidentifying a male plant.

Be aware, however, that feminized plants can still exhibit hermaphroditic traits under stress.

Preventing Unwanted Seed Production

As an experienced cannabis grower, I’ve witnessed firsthand the peculiarities of cannabis plant reproduction.

Remember, plants (like most living things) have a life mission to reproduce, and sometimes, they find unusual ways to achieve that goal.

If you find a seed on your virgin (female) cannabis plant, it will grow into a female plant because it only has female genetic material to work with.

So, plant that little “bastard” and enjoy.

And don’t forget; a plant can always throw a “nanner” (a banana-shaped male part that shoots out), so keep an eye out for those surprises!


Why did my female plant produce seeds?

Your female cannabis plant may have produced seeds due to self-pollination, hermaphroditism, or stress-induced pollination.

Can you make a female plant produce seeds?

Yes, you can force a female plant to produce seeds by inducing it to grow male flowers with viable pollen using methods such as spraying with gibberellic acid or colloidal silver to create feminized seeds.

Can plants produce seeds without pollination?

In general, plants require pollination to produce seeds. However, some plants can self-pollinate or reproduce asexually through apomixis, which doesn’t require fertilization.

Are hermaphrodite seeds viable?

They can be viable but have a higher chance of producing hermaphrodite plants, which is less ideal for high-quality, seedless buds.

Do feminized plants produce feminized seeds?

Yes, if induced to self-pollinate, feminized plants can produce feminized seeds.

Can some plants produce seeds without fertilization?

Yes, some plants can produce seeds without fertilization via a process called apomixis, but this is uncommon in cannabis.
