Did you know the gender of a cannabis plant makes a big difference in the outcome? Come learn more about male vs. female cannabis plants and discover why this is so important to know, especially if you are growing for the first time!

Why You Will Love This Guide
Unlike most plants, cannabis plants have specific male and female genders with unique characteristics.
As members of my Well With Cannabis Community know, the sex of cannabis plants makes a huge difference, whether you are using it for recreational purposes or medical.
In most cases, we want the female flowers, as they produce the cannabinoids that we want - for edibles, topicals, smoking, or more.
In this guide, I will teach you why the sex of the plant matters, how to identify the sex of your plant, and how to ensure you get more females in the future.

Male vs. Female Plants
Most plants are monoecious, containing male and female reproductive organs in a single flower.
However, cannabis plants are dioecious, meaning each plant has male or female reproductive organs.
Male marijuana plants, or hermaphrodite cannabis plants, have fewer cannabinoids and fewer psychoactive and beneficial effects.
In addition, the male cannabis plants usually contaminate the female plants by fertilizing them from their small pollen sacs.
Once fertilized, the female marijuana plants spend more energy on seed production rather than producing flowers and cannabinoids, thus compromising their quality.
This is why most cannabis growers prefer to grow only female crops.
How To Differentiate
It is crucial to differentiate between the male and female cannabis plants during the growing process.
The process of growing cannabis has two stages:
- The vegetative stage
- The flowering stage
The vegetative stage is the period when the plant grows bigger and taller, and it is impossible to tell the gender with the naked eye at this stage.
However, you can distinguish between the male and female cannabis plants with their morphological differences during the flowering stage.
It is important to differentiate between males vs. females at the beginning of the flowering stage.
While you should easily see the differences with your naked eye, you can use a magnifying glass or jeweler's loupe to look closer at the male and female parts.
Features of Female Cannabis Plants
The female counterparts contain tiny white hairs that grow at the base and joints of the plant's nodes.
As the female plant matures, these white hairs grow more prominent, and their color changes to a reddish hue.
When you want to identify a female cannabis plant during the early stages of the flowering phase, it is helpful to look for the following physical characteristics:
- Resinous buds
- Slender stalks
- Female sex organs - V-shaped female pistils with a protective layer called the calyx
- Abundant fan leaves and sugar or trim leaves
- Shorter than male plants
- Fine translucent hairs, wispy white hairs, or orange hairs
- Seedless buds

Features of Male Cannabis Plants
Generally, male plants are tall with thick stems at the flowering stage, and their branches have fewer leaves.
The joints of their branches have male pollen sacs that resemble a clump of bananas.
You should look for these physical characteristics to distinguish a particular cannabis plant as a male:
- Pollen sacs that form green and white flowers
- Pollen grains
- Sparse, tiny leaves
- Thicker stalks, sturdy main stem
- Taller than female plants
In most cases, growers want to remove or destroy the male cannabis plant before it can pollinate the female.
Just a little bit of pollen released from a male plant can stunt the growth of the entire crop of female flowers.
However, males and pollen production play an important role in creating new genetics, and this may be an avenue to explore if you want to go on and create different cannabis cultivars and new strains.
Males may also be used for juicing, the cultivation of hemp fiber, genetics, and more.
In rare cases, a hermaphrodite plant may occur among cannabis plants, as well.
A hermaphroditic plant will contain both female reproductive parts and male reproductive parts in a single plant.
In most cases, growers will remove these plants because this type of weed produces lower-quality flowers and buds along with regular seeds.
It Starts With The Seeds
If you are new to growing cannabis and want to ensure you are only planting female flowers, you must start with the right type of seeds.
When shopping, most people want to focus on Indica vs. Sativa, what strain to pick, and how it will make them feel - but that's not most important.
Regular cannabis seeds, purchased from seed banks or gathered from a growing plant, produce either males or females.
This means you have a 50/50 chance of planting and growing a male plant.
The best way to ensure you only grow female weed plants is to start with female seeds.
These are typically labeled as "feminized seeds" when purchasing them.
The resulting seeds will only produce female cannabis plants, the type of plant we usually want.

Other Things That May Affect Growth
Of course, many factors affect the growth of your cannabis plant beyond just the plant's gender.
These factors may include:
- growth cycle - autoflower vs. photoperiod
- poor genetics - different strains grow differently
- nutrient deficiencies
- enough water
- light schedule, grow cycle, and hours of light
- environmental factors
- growing space either outdoors or in a grow room
Both male and female cannabis plants can be helpful, but the female variation tends to have more benefits than the male one.
Female genetics are for you if you are looking for a high THC content, maximum cannabinoids, and terpene production.
This will ensure the quality of the final product of whatever you make is the best possible.
