Sexing Cannabis: How to tell if your plant is male or female?
If you grow regular cannabis seeds you will find the resulting plants to be a mix of male and female cannabis plants. Apart from breeders, most people discard the male plants as soon as they are identified. This prevents them pollinating the female plants, which would fill the buds with seeds.
But before you throw any plants away, you need to be confident about the differences between male and female cannabis plants. Identifying male and female cannabis is known as sexing cannabis plants.
Difference between male and female cannabis plants
Most people grow cannabis for the potent buds. That means growing female cannabis plants. Male cannabis plants do produce THC, but not generally in the amounts worth the inconvenience of growing them. Few people (other than cannabis breeders) want to see seeds in their cannabis buds.
Female plants produce the buds we are familiar with. Male plants produce small pollen sacs, these look like small balls. When they open they look like miniature bananas, releasing cream-coloured pollen dust.
What does a hermaphrodite cannabis plant look like?
Hermaphrodite cannabis plants, also known as ‘hermies’, display characteristics of both male and female cannabis plants. Just like males plants, hermaphrodite cannabis plants are also usually removed from grow rooms to prevent pollination (and therefore unwanted seeding) of buds.

Male vs female cannabis plants look different and grow a little differently too. Male plants are often taller, giving them a pollen distribution advantage when their pollen sacs eventually open. The pollen sacs form at the nodes on the stem. Pollen can be collected and frozen if required e.g. for breeding purposes.
Pictures of male and female cannabis plants are a useful reminder to the novice grower should there be any doubt identifying male and female cannabis plants. Sexing cannabis, and understanding the difference between male and female cannabis plants prevents the disappointment of finding seeds in your buds later.
Male cannabis plant picture
Female plants produce the buds familiar to cannabis growers. Ensuring that no pollen is present keeps the buds seed-free, just the way the connoisseur grower likes it! Male or female cannabis seedlings can’t usually be separated/identified by sight alone. Cannabis professionals sometimes use DNA testing of leaf material from a young cannabis plant to determine whether it is male or female. This gives the professional cannabis grower the opportunity to identify his cannabis plants as male or female many weeks before the plant sex would normally be revealed.
Those interested in learning more about the various forms of DNA testing of cannabis plants may wish to check out Delta Leaf Laboratories. As well as offering a $10 DNA test for plant sex, they can also test for the types of future cannabinoids that are likely to be produced by your plants.
Cannabis sex is usually clearly visible soon after the plant is placed in bloom conditions. However, the observant cannabis grower may also occasionally notice that some plants can be identified during veg growth.
Male and female cannabis can be grown from regular seeds. Feminised seeds tend to give rise to around 95% female plants. Images of male and female cannabis plants are useful if the less experienced grower is unsure. Cannabis male female identification is an easy skill to learn.

Hermaphrodite cannabis plant pictures can show varying numbers of pollen sacs. Small numbers of them can be plucked off and the plant can be saved. Heavily affected hermies are often simply removed. Any seeds produced by cannabis hermaphrodite plants should be treated with caution – they may give rise to hermaphrodite cannabis plants if germinated.

How and when to tell if your cannabis plant is male or female
If you grow from feminised cannabis seeds or autoflowering seeds you may rarely see male plants. Male pollen sacs are easy to see, allowing males to be easily identified. Sexing cannabis pictures are a useful reference if you are new to the subject.
Sometimes, if bloom has only recently begun, it can be difficult to know for sure if you have male or female cannabis plants. If unsure take another look a day or two later, it may be easier to tell the difference.
Male and female cannabis seeds
Simply looking at a cannabis seed appearance can’t tell you whether you will have male or female plants in future. Only the genetics inside the seed will determine the final plant type.
Some old school growers and breeders prefer to use regular cannabis seeds which will produce male and female cannabis plants. But 95% of cannabis seeds sold are feminised seeds or autoflower seeds. These will usually only produce female plants.
Few cannabis growers can be bothered with the hassle of producing their own seeds. It’s easier to buy the best cannabis seeds they can get from a seedbank they can trust. If you grow good quality photoperiod feminised seeds, or autoflower seeds you should be assured of female plants and a great harvest.
What Marijuana Seeds Are Female?
As a rule of thumb, you cannot know what sex the Marijuana seeds are by just looking at them. Even Feminized Marijuana seeds are 99.99999% certain to be female. The only way you can find out what marijuana seeds are female is by germination. After two or three weeks, you will see the male or female flowers and this is the only way to know for sure what marijuana seeds are female.
You know what marijuana seeds are female, but why all the fuss?
Feminized marijuana seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized marijuana seeds mean that they are treated to make them female marijuana seeds (hence the name feminized) so that all the marijuana seeds can be used to get flowers. Breeders usually sell feminized marijuana seeds for their strains because they are easier to grow than regular female marijuana seeds and are too unstable to reproduce, although some people use female plants from feminized marijuana seeds to get cuttings, it is advisable that they use female from Regular marijuana seeds. It is recommendable to start growing with Feminized marijuana seeds, this will mean that the final plant won’t have any undesirable surprises like marijuana seeds reducing potency since there are only female marijuana plants.

Male vs. Female Cannabis- Why it’s important to know before you grow
Just like humans, cannabis and hemp plants are considered dioecious, meaning they have either male or female reproductive organs. Depending on the goal of the cultivator, it’s crucial to know the gender of their plants prior to harvest.
Both male and female cannabis plants have their benefits; growing both can result in cross-pollination and thus seeds, resulting in new genetics or seeds for the next crop. However, if your goal is to produce quality buds rich in cannabinoids, it’s crucial to isolate the males from the females to avoid pollination and seed production. Cannabis pollen is extremely potent; studies have shown that pollen can drift across 3 to 7.5 miles, and can reach over 30 miles if high winds are present.
Removing males will allow the female plants to grow abundant, seedless buds (called sensimilla ). When female plants are left unfertilized, they use that extra energy meant for reproduction to produce higher levels of cannabinoids like THC or CBD, depending on the strain. The resinous buds consumers purchase at dispensaries are all sensimilla.
How to Visually Determine the Sex of a Cannabis Plant
Cultivators can visually determine the gender of their plants about 4-6 weeks into the growth cycle (though this may differ for indoor grows) when the plant is transitioning from its “vegetative” stage into the “flowering” stage. At this time, the plant is no longer focusing its energy on growing bigger and taller and instead spends all its effort growing flowers for pollination and reproduction.
When a cannabis plant is beginning to enter the flowering stage, cultivators should pay careful attention to the area between the nodes of the plant, where the leaves and branches extend from the stalk. Pre-flowers will begin to form in the nodes of the plant, and characteristics of the pre-flower will vary based on gender.
Pre-flowers can initially be difficult to examine with the naked eye, but growers can use a magnifying glass to get a closer look. Female cannabis pre-flowers grow as tiny bracts which will eventually produce hair-like stigma; male plants produce small, round balls as the nodes.
In some cases, a plant may exhibit both male and female pre-flowers. Hermaphrodite cannabis plants can occur when a plant becomes excessively stressed due to things like plant damage, bad weather, disease, nutrient deficiencies, and poor genetics. Hermaphrodites can also produce anthers, often referred to as “bananas” due to their appearance. It’s important to monitor plants that have been exposed to stressors to ensure they don’t begin to develop both male and female genetics. Hermaphrodites are capable of producing pollen and can ruin an entire crop.
How to Determine Gender Before the Pre-Flower stage
Lab genetic testing can determine a plant’s gender as soon as it begins to sprout its second set of true leaves. Knowing sooner can help cultivators save money, increase canopy space, and decrease labor costs associated with transplanting, watering, monitoring, training, and removing unwanted male plants.
Just as humans have X and Y chromosomes, cannabis also has a genetics system that determines the plant’s gender. However, figuring out the gender based on the DNA of a plant prior to the flowering stage is not as simple as looking for an X and Y. Luckily, the specific genetic sequence that differs between female and male plants has long been discovered, so using quantitative polymerase chain reactions (qPCR) allows labs to determine the gender of any plants with 100% confidence.
When a sample is brought in to Infinite Chemical Analysis Labs for gender identification, qPCR analysis is used to determine if the plant is female or male. A small hole is cut out of the leaf of the plant and added to a lysis solution to destroy the plant cell walls, exposing the DNA. After isolation of the DNA, it is transferred to another plate that contains reagents to amplify and cause the sample to create a fluorescent light that our qPCR instrument then quantifies, and determines the gender of the sample based on the amount of fluorescence.
Between sufficient lighting, proper nutrients, a detailed watering schedule, and constant monitoring, identifying the sex of your plants is another tedious yet crucial task that could make all the difference come harvest season.
