Male Cannabis Plants vs Female Cannabis Plants: Differences & Similarities

Male Cannabis Plants vs Female Cannabis Plants: Differences & Similarities

Cannabis is a dioecious plant, meaning its male and female reproductive organs are different in plants. Essentially, a male cannabis plant generates pollen that fertilizes the flowers produced by their female counterparts. Hence, whether you have an outdoor or indoor cannabis growing operation, knowing the difference between these variants is crucial. 

People predominantly cultivate cannabis for their flowers, so most growers focus on female plants. The flowers are also called buds and are rich in THC and CBD. The distinctions between male vs female cannabis start to appear later in the plant’s life cycle. 

Our in-depth guide explores both variants and provides valuable insight into how to distinguish them. Similarly, it provides excellent tips for growing marijuana to help you get the most from your plants. So, whether you have a state-of-the-art grow room or growing marijuana with minimal equipment, this guide can help you get the best results. 

Anatomy and Physical Differences

The most apparent difference between male and female weed plants lies in their physical appearance. As they mature, cannabis plants develop specific reproductive organs that make it easy to identify their sex.

Male cannabis plants are typically taller and more slender, with fewer branches and leaves than their female counterparts. They produce pollen sacs, which are small, round structures that hang in clusters from the plant’s nodes.

Female cannabis plants, on the other hand, are generally shorter and bushier. They produce pre-flowers with pistils, which are hair-like structures that capture pollen from male plants. Pistils can be white, brown, or even red, depending on the particular strain.

Growth and Life Cycle

The life cycle of cannabis plants comprises various stages. These are germination, vegetative growth, and flowering. As cannabis plants progress through various developmental phases, the distinctions between male and female plants become increasingly evident.


Male and female cannabis seeds are indistinguishable during the germination stage. It is only after the plants have grown for several weeks that their sex becomes apparent.

Vegetative growth

During the vegetative stage, the male and female cannabis plant focus on growing strong roots, stems, and leaves. However, male plants often grow more rapidly than females and are generally taller.


During this stage of the weed plant’s growth, the differences between male and female plants become more noticeable. Male plants develop pollen sacs, which eventually open and release pollen into the air. Female plants produce flowers, or buds, rich in cannabinoids like THC and CBD.

Reproduction and Breeding

Understanding the reproductive behavior of male and female cannabis plants is crucial for cannabis cultivation and breeding. Male cannabis plants are responsible for pollinating female plants, which then produce seeds. These seeds carry the genetic material from both parent plants and can result in unique, hybrid strains.

When pollinated, a female marijuana plant will invest energy into seed production rather than cannabinoid and resin production. When a flower utilizes its energy to produce seeds, it has less energy to make cannabinoids like THC. As a result, this is unfavorable for cultivators since it reduces the potency of the flowers.

A majority of cannabis cultivators grow female weed plants separately to avoid the development of seeds. Similarly, many farmers opt for female cannabis plant clones rather than seeds when planting their crops. 

Uses and Applications

While female cannabis plants are highly sought after for their cannabinoid-rich buds, male plants also have their uses. The male marijuana plant can be utilized for breeding purposes. This is because pollen is essential for creating new strains. Additionally, male plants contain small amounts of cannabinoids, which can be extracted for use in topical applications or infused products.

On the other hand, female weed plants are rich in cannabinoids. Consequently, they serve both recreational and medicinal functions. Its flowers can be consumed in various forms, including smoking, vaporizing, or creating edibles and oils.

The Bottom Line

Understanding the differences and similarities between male vs female weed plant variants is fundamental for successful cultivation. Despite not being as valuable as their female counterparts, male marijuana plants play a crucial role in the cannabis ecosystem. By appreciating the unique characteristics and uses of both sexes, we can continue to harness the full potential of this versatile plant species.
