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.
Cannabis Gender: Male Versus Female Plants
Many growers believe they cannot correctly identify the sex of their cannabis plant until the flowering stage. Good news! Cannabis “pre-flowers” will help you to identify the sex of your plant within 3-6 weeks of germination. These pre flowers can show up on male plants as early as 3-4 weeks from germination and on female plants as early as 4-6 weeks from germination. These results may not always be accurate so it is always best practice to wait until flowering to be 100% sure on the sex.
Yes! Female cannabis plants will create seeds when a male plant pollinates them.
Only female cannabis plants produce buds!
How to tell if your cannabis seeds are male or female?
Cannabis seeds are normally 50% male and 50% female. If you are wanting to grow a female plant from seed, you can order feminized seeds online. If male cannabis plants are introduced into a garden with females, this will cause pollination which will result in the female plants producing seeds. Buds with seeds produce a harsh smoke and a low quality product.
It is possible to get hermaphrodite cannabis plants. That would be a plant that developed both male and female sex organs. So the plant is capable of pollinating itself, and every plant in the grow room!
Male cannabis plants produce pollen which can fertilize female plants and cause them to produce seeds.
How to identify the gender of your cannabis plants?
Male cannabis plants will develop their pollen sacks before the females produce buds. It only takes 1-2 weeks for pollen sacks to show up on the male plant. Females show their gender around 2-4 weeks.
When looking to tell what sex a cannabis plant is, you have to look at where the branches grow off the stalk. These are called nodes. If your plant is a male, it will have round balls on the nodes. If your plant is female, it will have small flower clusters with long “hairs” poking out. These differences will be apparent around 4 weeks into plant growth, they are called pre-flowers.
Examine your plants carefully as identifying sex in the first month of grow can be very difficult.
Things to look for when determining gender:
- Male plants are normally taller
- The calyx (center part of flower) on female plants will be large and have white hair. On male plants it will be small with no hair.
* You may need a magnifying glass to tell the distinction at this stage!
To get the highest quality buds, growers will want to do everything they can to prevent pollination!
MALE CANNABIS PLANT
How to identify a male cannabis plant:
Male plants will mature much faster than female plants. They will grow faster and within 2 weeks should be taller than the female. They will begin their flowering stage almost a month before the female plants.
Features of Male Plants:
- Less flower development
- Straight growth
- Flowers will be close knit green clusters
FEMALE CANNABIS PLANTS
How to identify a female cannabis plant:
Male plants have what is often referred to as “false buds” but they are in fact pollen sacs!
Female plants, on the other hand, have flowers that will resemble sacs. These sacs open to have yellow or white flowers. Additionally, they will have pistils (resembles hair).
Features of Female Plants:
- Flower development
You can guarantee females by getting feminized seeds or female clones!
What about hermaphroditic cannabis plants?
Some cannabis plants can be hermaphrodites. This is when the female plant will develop both the male and female sex organs! A hermaphroditic plant can result in the plant pollinating itself and your entire grow. This most often occurs when your plant is stressed out. Monitor the temperature, humidity, and pH closely! And always look out for pests, pathogens, diseases, and other factors that may cause your plant stress.
Male and female cannabis plants must be separated unless you want to produce seeds!
What to do when you get a male cannabis plant?
Most growers find and terminate all male cannabis plants in their grow. This is understandable if you want to ensure no female plants get pollinated. However, male plants are still of value. If you want to continue to grow your male plants we recommend growing them in a separate room from the females to discourage pollination. Male cannabis plants can be used for breeding, concentrates, hemp, and more.
When a male and a female cannabis plant are bred, the male provides 50% of the genetics. This can be helpful in breeding strains that are mold resistant, have more resin, higher THC content, etc.
Most growers dispose of male plants
While male plants often contain less THC than female plants, you can still find cannabinoids in the leaves, stems, and flowers. You can extract resin from male plants to create concentrates like hash, oil, and wax. Even the pollen contains THC! Male plants produce copious amounts of pollen, which can be collected, pressed, and consumed to give you an adequate high.

When it comes to harvesting home-grown marijuana, female plants are the name of the game. Not only do female plants produce the coveted buds needed for medicinal purposes, but they also have higher potency and THC content compared to their male counterparts. You’re in good hands—we’ve outlined everything you need to know about identifying female and male marijuana plants, so you can easily make the most out of your crop at home.
Look for thicker, sturdier stalks with fewer leaves on male plants. A male plant, compared to a female plant of the same strain, generally has a thicker stalk. That is because it gets taller than female plants and needs to be able to support the weight. They also have fewer leaves than female plants.  X Research source
- You need to check every plant to determine if it is male or female, as one rogue male can wreck your harvest.
- In general, male plants show their sex 7-10 days (indoor) or 3 weeks (outdoor) before female plants.
- If you’re trying to create new plants or reproduce, you need to leave these balls undisturbed.
- Female plants will have these bulbs too, but will also have long, translucent hairs on them. If you only see 1-2 on a plant, wait and see if more develop before cutting them.
- “Hermies” are generally undesirable plants, and they can ruin a small crop with their pollen if you’re not careful.
Throw out or remove male plants unless you specifically want seeds. Once you’ve determined a plant is male, you need to get rid of it or it will ruin your crop. Do not try and remove the buds by hand, as missing even a few will significantly decrease your crop. While most growers simply throw the plants out, a few keep them around for breeding purposes. If you do, put them in a separate room from the females, and make sure you don’t track pollen in from the male room to the female room on your clothes or hands.

- You can purchase “feminized” seeds as well, which usually create close to 100% female plants. However, there are occasional errors, and you should still keep a close eye on your plants to make sure there are no rogue males.

Note fuller bodies of leaves, when compared to males, on a grown female plant. If you’re trying to sex mature plants, one of the easiest indicators is how bushy they get. Male plants have thicker, sturdier stalks and very few leaves. A female of the same strain will be shorter and bushier, with more leaves, especially near the top.
- Male plants will have the small buds (pollen sacs) but will not have the associated hair growing out of it.
- Plants can grow both pollen sacs and pistils. If it does, it is hermaphroditic and should be treated like a male.
Separate your females from any males, as only females create buds. Only female plants will produce enough THC to be used as medicine, but they won’t create much if they become fertilized. The pistil is meant to attract pollen. If it gets it, it will create a seed, and all the plants energy and nutrients will be spent making seeds, not making big, THC-full buds. Your female plants are the only ones that will produce a crop, but only if they stay away from the males.
In general it’s not a good idea, because you can bring bugs and other things into your house, but as long as it’s not being kept around indoor plants, it should work. Just make sure to keep an eye on the plant and give it plenty of fresh air, as that is likely what it is used to. Keep in mind that the sun is the best grow light, though, so you should leave it outdoors if you can!
It needs a light cycle with a minimum of 12 hours of uninterrupted, complete darkness every day to trigger and maintain flowering.
Check frequently once your plants have hit the 6-week mark — you want to know you plant’s sex as soon as you can.

If you’re growing marijuana plants, it’s important to be able to tell male and female plants apart, since only the females produce the buds that contain high concentrations of THC. To identify male and female marijuana plants, make sure they’ve been growing for at least 6 weeks, since both types of plant look the same in their early stages. Then, look for male plants to have thicker stalks and fewer leaves than their female counterparts. You can also tell if a plant is male by checking for little flowers or bulbs at the joints of the stalk and branches. By contrast, you’ll see small, translucent hairs on the same areas of a female plant. Once you’ve identified that a plant is male, remove it from your growing area to prevent it from pollinating the female plants, which will result in your THC harvest being reduced. For tips on what to do with plants that have both male and female organs, read on!
