 Identifying Male and Female Cannabis

 Identifying Male and Female Cannabis, Here we offer an in-depth exploration of cannabis plant anatomy, highlighting the differences between male and female plants. We provide detailed descriptions, charts, and cultivation tips tailored to each gender, aiding both novice and experienced growers in mastering this crucial aspect of cannabis cultivation.

Reproduction processes occur in the plant world in different ways. Monoecious plants are distinguished by two types of flowers in similar plants, and hermaphrodite plants grow separate flowers that have male + and female reproductive organs.

Cannabis is a dioecious plant, that is, the appearance of various reproductive organs is possible on different plants.

Node Placement and Internodal Spacing:

  • Female Plants: Typically exhibit closer internodal spacing, resulting in a more compact and bushy appearance. This feature is not just aesthetic; it supports the plant’s ability to bear the weight of the buds as they develop.
  • Male Plants: Have longer internodes, giving them a taller, lankier appearance. This structure is suited for their role in dispersal of pollen over wider areas.

Comparative Anatomy of Male and Female Cannabis Plants


  • Female Plants: Display pre-flowers in the form of tiny, translucent hairs or pistils, which emerge at the nodes. These pistils are crucial for catching pollen during the blooming stage.
  • Male Plants: Develop small, sac-like structures known as pollen sacs. These are the containers for the pollen that will fertilize the female plants.
Feature Male Plant Characteristics Female Plant Characteristics
Node Placement Longer internodes, taller appearance Closer internodal spacing, bushier look
Pre-Flowers Small pollen sacs at nodes Small, translucent pistils at nodes
Leaf Structure Slightly elongated leaves Broader, more uniform leaves
Branching Patterns Simpler, less dense branching Complex, dense branching for bud support
Overall Growth Taller and less bushy Compact and bushy

Male Cannabis Seeds: How to Use

The guarantee of female genetics is possible by obtaining clones in combination with feminized seeds. If specialists working with seeds do not know the gender of the cannabis, this can negatively affect the result of the growth as a whole. Knowing how to distinguish cannabis contributes to the development of genetics and seed productivity.

How to determine the sex of cannabis easily

The pre-flowers of the female cannabis grow as tiny bracts with a stigma protruding from the hair. And male cannabis produces small round balls in knots.


It is possible to determine the sex of hemp due to the peculiarities of the development of internodes. The male plant may develop the pollen sacs needed to disperse the seeds, while the female plant will develop pollen. These differences can be observed a week before the start of the actual performance of their functions in the breeding cycle. They are called “preliminaries”.

The development of preliminary flowers begins after 4 weeks, but this process may be longer, according to the speed of the germination phase. How to find out the sex of cannabis at this time? In the 6th week, the specialist has the opportunity to detect preliminary flowers – to confidently determine the sex of their plants.

Due to the presence of small preliminary flowers, it is difficult to identify them with the naked eye, but gardeners can use a magnifying glass for a closer look. European growers are researching plant nodes, looking at the early development of small flowers on males or 2 bracts on females, resulting in a hairy stigma.


Although there are many other methods for distinguishing the sex of cannabis, familiarization with the emerging pre-flowers is recognized as the most reliable.

The operation, in which the male cannabis plant is removed at an early stage, is important to free up space and ensure quality growth of the female plants, as well as to prevent pollination.

Leaf Structure:

  • Female Plants: Often have a more uniform and broader leaf shape, which is conducive to photosynthesis and bud development.
  • Male Plants: Possess slightly elongated leaves. While this difference is subtle, it can be a helpful indicator when combined with other traits.
  • Visual Chart: An illustrative comparison of leaf structures can enhance the grower’s ability to differentiate genders based on foliage.

Branching Patterns:

  • Female Plants: Exhibit a more intricate branching structure to support the development of buds.
  • Male Plants: Have a simpler and less dense branching pattern, as their primary function is pollen production and not bud development.
  • Visual Chart: Illustrations of the branching patterns in male and female plants can guide growers in recognizing the plant’s gender based on its overall silhouette.

Overall Growth Patterns:

  • Both genders exhibit similarities during the early stages of growth, making early identification challenging. However, as they mature, the differences in growth patterns become more apparent, aiding in gender distinction.

How to determine the sex of marijuana and what are called hermaphroditic cannabis plants?

Managing Hermaphroditic Cannabis Plants

Factor Description and Management Strategies
Characteristics Buds and pollen sacs or anthers (‘bananas’)
Causes Genetic factors and environmental stress
Management Regular inspection, isolation or removal
Preventive Measures Maintain stable environment, choose quality genetics

If females develop male + and female reproductive organs, they are considered hermaphrodites, with the ability to produce pollen capable of pollinating the entire plantation. According to some experts, such cultivation contributes to excessive plant stress. It is accompanied by some plant stressors, consisting in:

  • plant damage;
  • worsening weather;
  • the development of diseases;
  • lack of nutritional supplementation.


Hermaphroditic plants are represented by:

  1. Individuals that develop buds in combination with pollen sacs;
  2. Individuals that produce anthers, commonly referred to as “bananas”, due to appearance.

These processes are accompanied by the stress state of plants, so it is necessary to control them after exposure to a stressor. The cause of indoor stress is an increase in temperature or a decrease in light levels. The reason for exposure in outdoor areas is the breakage of branches, which can lead to the phenomenon of hermaphrodite cannabis.

The main reason leading to the emergence of hermaphroditic plants is genetic. According to experienced experts, if a plant has poor genetics or a history of hermaphrodite development, it should be removed from the plantation, which is important for protecting the garden. When pollen sacs or anthers appear, gardeners in many countries take steps to remove the plants and prevent pollination of the females.


In the complex world of cannabis growth, knowing the detailed differences between male and female plants is a gardening skill that can significantly impact your harvest. As a grower, being able to identify the gender of your cannabis plants is akin to unlocking the secrets of their growth.

In this piece, “Growing Wisdom: Understanding and Identifying Male and Female Cannabis Plants,” we start on a trip through the basic parts of cannabis genetics. We’ll dig into the obvious signs that distinguish female plants, study the unique traits of their male peers, and give you with gardening tips tailored to each gender.

Whether you’re a seasoned grower or a new fan, improving your knowledge of cannabis gender recognition will surely contribute to a more successful and satisfying growing experience. Let’s solve the secrets together.

1. Characteristics of Hermaphroditic Plants:

  • Buds and Pollen Sacs: Hermaphroditic cannabis plants may develop buds characteristic of female plants along with pollen sacs typical of male plants.
  • Anthers or ‘Bananas’: In some cases, hermaphroditic plants produce anthers that resemble small bananas. These structures can also release pollen.

2. Causes of Hermaphroditism:

  • Genetic Factors: Some cannabis strains have a higher propensity for hermaphroditism due to their genetic makeup.
  • Environmental Stress: Factors such as damage to the plant, extreme weather conditions, nutrient deficiencies, and improper light cycles can trigger hermaphroditic tendencies.
