It is critical that you know how to identify which of your plants are male vs female. This guide will explain cannabis gender & reproduction. When you grow cannabis at home, sexing the plant can be a critical step. Distinguishing between males and females is vital for home growers to grow cannabis
Sexing marijuana plants & reproduction
Understanding marijuana gender and reproduction is essential to achieving the best possible harvest. However, it can be confusing.
For marijuana growing success you need to know what feminized seeds are and how to identify your plant’s gender.
This guide will explain these cannabis reproduction topics, as well as other important fundamentals such as what are hermies, and why so many people love sinsemilla.
We’ll also share some ideas on how to make a male plant female.
Cannabis gender identification & reproduction guide
Cannabis plant reproduction
First, let’s talk gender. Unlike most flowering plants, cannabis plants are dioecious, meaning there is a separate male and female plant, similar to humans.
Every plant possesses two pairs of sex chromosomes, X-chromosomes and Y-chromosomes.
Male plants have XY chromosomes, while female plants have XX chromosomes. Also, like humans, there is a natural 50/50 split between males and females.
There is a significant difference between the gender of marijuana and humans, however.

- Avoid common grow mistakes
This is because a marijuana plant can also be hermaphroditic. This means a single plant can have both male and female genitalia (a pistil and stamen).
Unlike humans, a cannabis plant’s gender depends not just on its genetics but also on environmental factors.
That is one reason why, when growing marijuana, you should be familiar with the different traits of female versus male plants.

Each gender has unique qualities that may or may not be desirable in your garden.
Identifying males and females
It is critical that you know how to identify your male and female plants. However, it can be a bit tricky because cannabis plants do not start with gender.
Plus, they won’t truly reveal their gender until they start receiving 12 hours of darkness every 24 hours. In some cases, that is too long to wait.
Why do you need to know?
The simple reason is this:
Females produce THC and males distract them from it. Therefore, you want to determine the sex as soon as possible so that the males do not fertilize the females.
To explain it further:
Females without seeds (sinsemilla) have higher levels of THC, whereas males produce significantly less THC.
Preventing pollination, therefore, is the best way to ensure the highest quality buds.
Knowing what to look for
In terms of identifying between the two, in general, males have flowers, while females have pistils. Males tend to be taller as well.
All marijuana plants have flowers at some point. However, if you can’t differentiate between males and females on height alone, then flowers and pistils are good indicators.
This may seem simple, but to be honest, identifying the sex of a cannabis plant can be hard.
This is because marijuana plants don’t disclose their gender until they are mature enough to do so.
In fact, you may not know until your plants are almost ready to begin pollination.
If you wait this long to identify the sex of your marijuana plants, then it’s probably too late to grow sinsemilla buds.
Female cannabis plant
Female plants are often very recognizable. While both males and females will form flowers, the flowers from female plants usually do not bloom until after the males.
The females’ flowers will look like sacs that grow two stigmas (they sort of look like feathers) out of them.
Here are two features of females:
- They eventually open to form little yellow, cream or white flowers
- They have hairy, whitish pistils that trap pollen from males
You’ll find the stigmas in a node region of the main stalk. This is where a branch grows from the main stem, or where a branch grows from another branch.
Male cannabis plant
The easiest way to identify a male is by its rapid maturity. Males mature faster than females, meaning they will grow quicker and become taller about two weeks before a female plant. This is so they can drop pollen on female plants. Their flowering phase can begin as much as a month before females, giving growers some time to identify them.
Despite what you may have been told, male cannabis plants are not completely useless.
Obviously if you are growing a crop to smoke or sell, then you want females.
If you’re growing for the purpose of making hemp, the male plants make for a softer fiber, which is great for making clothing. Male plants also produce far more seeds, which you need to grow more plants.
Here are some typical features of males:
- They tend to grow straighter and don’t develop as many flowers as females.
- The flowers are generally located at the top of the plant.
- Unlike the female flower, male flowers are tight green clusters.
The male flower has a central part that looks like petal-shaped objects, five of which are inside of the sex organs.
To the untrained eye, they look like a tiny banana bunch. Male flowers are sometimes called “false buds” since they are actually pollen sacs.
These clusters begin opening over time until a stamen appears – ready to pollinate the females.
It is challenging to identify the sex of a cannabis plant-based on flowers. This is because there is a very short window between when they appear and when the plant is fertilized.
Instead, expert growers do this to identify sex:
They focus on finding the preflowers. These develop at the tips of branches and on the main stem. Preflowers are the immature first flowers that proceed the mature flowers.
Basically, it works like this:
If you notice a raised calyx on a small stem or stalk, then it is most likely a male. If this calyx isn’t raised, then it is probably a female plant.
Yes, it’s that simple. It can be hard to see the difference at first, but over time, every grower gets better at it.
Other methods for identifying the sex of your plants
Sometimes, you want other options. Maybe you need to know sooner, or perhaps you just prefer to use a variety of methods. Here are a few other ways to identify the sex of your plants.
Look at the growth patterns.
During vegetative growth, every plant, regardless of sex, starts to flourish. As the plants age, however, you will notice subtle differences in their sizes.
Some marijuana growers have even noticed certain signs early on that can help determine the sex.
Females tend to have more complex branching when they progress from the seedling stage to the vegetative stage. Males, on the other hand, tend to be slightly taller and less filled out.
This method is not foolproof, and you shouldn’t use it as a reason to throw out a plant.
Of course, the last thing you want to do is pull plants out at this early stage.
There is a reason to try it, however. It can help you get an idea, so you know which plants to watch later on.
(Note: this works best on outdoor grown plants, as those grown indoors under artificial light don’t usually exhibit these tendencies).

Identify where the plant sprouted during germination.
Need to know as soon as possible? Some marijuana growers have discovered a method that identifies the sex of the plants just after germination.
According to their theory, if the sprout comes out of the top or bottom of the seed, it is generally a female. Side sprouts, on the other hand, generally turn out to be male.
While this hasn’t been scientifically studied, growers who have used this method report a 90% success rate.
Even with this anecdotal evidence, you shouldn’t use this as absolute fact. Let the plants grow a little and try to notice any distinctly male or female signs.
Don’t just throw away the marijuana seeds simply because they sprouted out of the sides.
Instead, keep track of your predictions so that you can make an informed decision later.
Clone your marijuana plants.
This is really the only foolproof way to determine the sex before the plants achieve maturity.
The best part about this technique is that it is easy. You merely take a cutting from one of your plants.
Cloning in 3 steps:
- Cut a small piece of the mother plant
- Place the cutting into potting soil and let it grow
- Force flowering with 12hr darkness/12hrs light after a few days
To identify the sex of your clones, you’ll need to keep them separate from the host plants.
This method works because, since they have the exact same DNA as their host, they will have the same sex.
Once the clones go into the flowering stage, it will be easy to determine their sex and the sex of their hosts.
Make sure you keep track of which clone came from which host, so you don’t get things mixed up.
You can also force the flowering of a regular plant (not a clone) and put it back into the veg stage once you know it is female.
However, this process can cause more trouble than it is worth. While effective at speeding up the reveal process, it can also place unnecessary stress on a developing plant.
Flowering and reproduction
Once your plants have developed their sex, they are ready for reproduction.
Here’s some detail on what happens during that process.

Female flower formation
On a female marijuana plant, a large cluster of buds appears. This cluster is called the cola, and it consists of many sub-units of buds.
Within the cola, there are many pistils, which moderate the female processes of reproduction. Each pistil contains the stigmas that interact with male pollen.
Throughout the flowering process, cola is preparing for reproduction. The plant stretches and develops its bud sites.
These sites house groups of female marijuana flowers seeking to be fertilized. New flowers form on the top side of these subunits, and small stigmas emerge from the pistils.
These thin structures are often recognizable by their white hair.
They can still be pollinated even if they are not white.
Stigmas can sometimes die – especially after heavy rains or wind. This will cause them to become dry and change in color from brown to red.
This does not mean that pollination cannot happen. Even if a stigma is this color (instead of white), it can still receive pollen.
The female flower also has other hairs – glandular trichomes. These “hairs” are responsible for producing resin on the flowers and nearby leaves.
Up close the resin looks like a ball attached to a tiny neck. Its shape is a good indicator of how delicate they are.
If you handle the buds roughly, some of these trichomes can break off.
Underneath the pistol, you will find a smaller leaf called the stipule. It is more noticeable before flowers are formed.
Once the plant is fully grown you will need to start thinking about harvest time.
Our free little Harvest Guide will help you determine the best moment to cut your plants. Download it here.
When a male marijuana plant matures, it releases pollen and seeks out the female stigmas.
The pollen then travels to the egg cell located inside of the pistil, producing a seed. If this process does not happen, the female flower begins to change.
The fact is, Cannabis plants are designed to pollinate.
The pollen from a male plant can survive for a few days as it attempts to reach a female, increasing the cannabis plant’s chance of survival.
Pollen can survive on fabrics, and in air ducts. It can also be stored for intentional fertilization.
Female plants also do their best to be fertilized. Pistils grow larger when they are not fertilized. This is so they have an easier chance of locating pollen.
However, this effect does not last forever. When the pistils are completely mature, the stigmas will die, and they cannot be fertilized.
At this point, resin production will slow down or stop, and the trichomes will begin to break down.
The last opportunity for fertilization marks the beginning of the plant’s death, but it is not immediate death.
Pistil maturation occurs gradually, instead of all at one time, leaving growers plenty of time to harvest.
What about autoflowering seeds and plants?
Most standard marijuana plants start to flower at the end of summer as days start to get shorter and the amount of light drops.
Regular plants recognize that they need to start maturing before the onset of winter, but autoflowering plants are different.
They will enter the flowering stage even if they receive a full 24 hours of light.
An automated flowering period is great for growing in places with unusual growing seasons, or when you’d like to harvest twice in a single growing season.
This is because a decrease in daylight hours (typically triggered by the change in seasons) is not needed for these plants to flower.
Feminized autoflowering seeds provide the dual benefits of a quick harvest and not needing to identify plant sexes.

Buy autoflower seeds
- Flower automatically
- Fast and easy to grow
- From seed to bud in just 10 weeks!
- No light cycle management needed
- The best beginner option
Autoflowering marijuana seeds also produce plants that are generally small and ideal for outdoor growth. With these, you can plant a couple for every square foot.
Plus, they only take about 10 weeks to harvest. That being said, the yield and quality are not up to par with seeds that flower regularly.
The features of autoflowering plants
- Generally, 12 to 23 inches tall (30 to 60 centimeters)
- Suitable for outdoor growth
- Starts flowering automatically after around 3 weeks
- Yield between 0.5 to 2 ounces depending on hours of sun
- Goes from seed to harvest in about 9 to 10 weeks
Autoflowering seeds will yield between 50 and 500 grams per m2, but this depends on how well you care for your plants.
Prevent fertilization with feminized seeds
Many growers prefer cannabis that is not pollinated and does not have seeds. It is called sinsemilla, which is Spanish for without seed.
Because these plants did not produce seeds, their plants tend to have more trichome production and more potency.
Feminized seeds help prevent fertilization by ensuring your seeds grow into female plants. If there are no male plants nearby, your female plant will not form seeds.
Many growers try to prevent pollination. Here’s why you should consider growing sensimilla using feminized seeds.
Save the energy for the buds
Pollination means that the plants will use their precious energy for creating seeds instead of flowers. This has evolved due to natural selection.
Since a plant that produces more seeds is more likely to reproduce many future plants, the trait is passed on.
Although this is an advantageous feature for marijuana’s survival, it is not exactly what smokers are looking for in a weed plant.
When female plants grow into maturity without being fertilized with male pollen, they can usually produce a more resinous bud. This is because there are no seeds to take over the valuable flowering area.
Sinsemilla is difficult to grow
Sinsemilla weed is expensive not just because it is high quality. It’s also because preventing pollination is hard.
Your female plants could be pollinated by male plants from up to a mile away!
You could also simply identify the sex incorrectly or wait until it’s too late to separate the males from the rest of the marijuana crop.
If you make a mistake, don’t freak out.
While seeds aren’t always wanted, accidental pollination frequently occurs. If you are worried that it has happened to you, look for swollen calyx rings (beneath the stigmas).
If unintentional pollination occurs, remember that a few seeds won’t ruin a harvest.
After all, it may only be one flower, and your plant has hundreds of them. You can either pick those seeds off or leave it alone.
A few seeds aren’t bad
Although you probably don’t want them, producing a few seeds isn’t necessarily a bad thing.
If one crop is particularly delicious or potent, you want those plants to produce a few seeds.
Store these seeds correctly and label them accurately so that you can identify which seeds produced the best crop later. Then, use the seeds that produced the desired traits in a future growing season.
Now that we understand the flowering stages’ role in marijuana reproduction let’s go more in-depth into the different sexes.
The female marijuana plant
Female marijuana plants take a tad bit longer than males to reach sexual maturity. But once they do, it is quite easy to spot them.
During the pre-flowering stage, the female plant will grow one or two wispy white hairs where buds will form. It means that the plant is ready to bud anytime soon.
The hairs will be visible on the main stem that connects to the nodes or branches. Once the hairs are spotted, that is a great sign that the plant is a female.
Ensuring female plants
Female plants tend to start showing hairs even before the flowering stage, or changes in grow light schedules, but they can still be fertilized by a single male. Most growers dream of having an all-female garden. This way they won’t have to deal with removing half their plants when they reveal themselves as male. This is where feminized seeds come into play.
Feminized seeds help improve your chances of growing female plants.
Feminized marijuana seeds are seeds that only produce female marijuana plants.
But they aren’t the only thing that makes a cannabis plant female. Under some conditions, female (and feminized) seeds can become hermaphrodite plants and fertilize themselves.
How feminized seeds are created
Are you wondering how breeders create a female seed? Here’s a summary.
Early feminized marijuana seeds usually were made with two female marijuana plants.
One of the plants would have already shown hermaphrodite tendencies, i.e., prone to produce male marijuana flowers when it was stressed.
The intersexual-prone marijuana plant is then stressed by light cycle interruption or pruning. The stress would encourage them to produce male marijuana flowers.
Then, the pollen from the hermaphrodite plant is applied to the ‘true’ female (i.e., a plant that did not easily display intersexuality when stressed).
The downside of this method is that the female marijuana ‘pollen donors’ already had quite a strong tendency to turn intersexual.
That tendency, in turn, was very likely to be inherited by the resulting feminized seeds.
In the early days of feminized marijuana seeds, hermaphrodites were a reasonable concern, but nowadays hermaphrodites formed from feminized seeds alone are rare.
Today, breeders use a technique called rhodelization. It uses different forms of silver to force female plants to produce male flowers.
This new, more intensive, technique produces stable and consistent seeds. Now, female plants with a very minor tendency to turn intersexual can be used, instead of the hermaphrodite plants needed in the past.
Best of all, none of the genes are modified, so the seeds produced are female.
These female plants stay female even when placed under harsh, irregular, or stressful conditions.
This means that their offspring have no more tendency that a normal female marijuana plant to turn intersexual.
If anything, the parent marijuana plants are physically modified by silver, and the seeds are produced naturally, through pollination.
Sexing Cannabis: How to Tell the Difference Between Male vs. Female Cannabis Plants
When you grow cannabis at home, sexing the plant can be a critical step. Distinguishing between males and females is vital for home growers to grow cannabis that they intend to sell. This article will teach you everything you need to know about sexing your cannabis plants when growing from home.
Sexing your cannabis plants after the flowering stage is the easiest way to determine whether they are male or female plants. Sexing your cannabis plants before the flowering stage while young can be challenging but still achievable. Home growers must sex their cannabis plants because male and female cannabis plants play different roles.
If you are not sure when it is appropriate to sex your cannabis plants, this article will help you out. Trying to determine the sex too early can lead to confusion. this article will help you avoid mistakes when differentiating between male and female cannabis plants while growing from home. Avoiding mistakes while growing is the best way to reap the most benefits while growing any plant from home.
Whether you are new to growing cannabis from home or an experienced grower, this article can help teach you how to differentiate between male and female cannabis plants. After you learn to differentiate between the two sexes for your cannabis plants, you will have an easier time growing cannabis in the future.
Difference Between Feminized & Regular Cannabis Seeds
One of the key differences you will need to know when growing cannabis plants is between feminist and regular cannabis seeds. Feminized cannabis seeds are treated so that the male chromosome cannot interfere with the growing process. People who make feminized cannabis seeds spray the seeds with colloidal silver to keep them feminized
People use colloidal silver to treat their cannabis seeds because it is non-toxic, making it a safe way to feminize cannabis plants. Regular cannabis seeds do not get treated with colloidal silver. For regular cannabis seeds, it is okay for male chromosomes to be present. When these treatments are performed regularly on cannabis seeds, the female plant will release female pollen instead of male pollen.
When female pollen is produced, growers can breed other plants with that female pollen to create female-only plants. Most home growers want female cannabis seeds because male cannabis seeds can reduce the quality of your female plants. In addition, if male pollen interacts with female plants, then the female plant’s energy goes more to see production than it does to cannabis production.
Feminized cannabis seeds will produce cannabis plants that can multiply more and have higher THC than male cannabis plants. Untreated regular cannabis seeds can yield either male or female cannabis plants. However, feminized cannabis seeds will only produce female cannabis plants because of the way that they were treated.
The critical difference between feminized and regular cannabis seeds is that feminized cannabis seeds are treated with colloidal silver to ensure that only female cannabis plants can be derived from the seeds. Un-feminized cannabis seeds can give you male or female cannabis plants, and male cannabis plants are undesirable for home growers.
The Formation of Feminized Seeds
Feminized cannabis seeds are not formed naturally. To feminize cannabis seeds, breeders treat the seeds with colloidal silver. The cannabis plants that sprout from these treated seeds are used primarily for seed production. These plants will only produce female seeds in the future, which is more desirable than seeds that produce male plants. Feminized seeds allow growers to take more control over their cannabis production.
The plants that sprout from the treated cannabis seeds are not ideal for smoking; even though colloidal silver is nontoxic, smoking these plants can alter the flavor and the effects of the plant’s yield. Plants as proud from altered seeds also our unideal for selling because they produce adverse effects when smoked.
Growers who choose to sell cannabis from plants that are derived from treated seeds from the risk of ruining their reputation. These seeds produce cannabis plants that are ideal for seed production only. These plants can also pollinate nearby cannabis plants; however, they should never be used for a final product.
Using these cannabis plants to pollinate nearby female plants is how growers ensure that all of their cannabis plants are female. When male pollen interferes with female plant production, the seeds that come from it can be male or female cannabis plants.
Sexing Cannabis Plants – The Role of Male and Female Plants
Some growers want milk plants in their inventory; however, most growers prefer only to have female plants. Male plants have their role in growing cannabis, which means they’re not entirely useless. They aren’t always ideal for home growers. Male cannabis plants are ideal for growers who want to experiment with the genetics of their cannabis plants.
Growers who want to experiment we cannabis plants for various reasons and alter the strains need to keep male pants around. However, these growers should also note that they should keep the male plants separate from female plants to have more control over their experimentation. When male cannabis pollen interacts with female seeds, the female will focus more energy on seed production than it will on growing cannabis.
Female cannabis plants are significantly more desirable for home growers and professional growers than male cannabis plants. This is because female cannabis plants produce larger and higher THC buds than male cannabis plants, so they are so sought after. Many growers remove male cannabis plants from their collection because if male pollen pollinates a female, it will interfere with the quality of the female buds. In addition, pollinating female cannabis plants with male pollen will cause the female plant to focus more on growing seeds than growing cannabis.
No matter what purpose the grower has for their cannabis plants is vital that they identify the sex of the plants early on in the growing stages. Growers that neglect to identify the sex of their plants will yield less potent and smaller buds. Accidental interaction between male pollen and female seeds should be avoided at all costs for growers.
When to Start Sexing Marijuana Plant
The sooner a grower identifies the sex of their cannabis plants, the better cannabis buds they will produce. When a grower can identify the male and female cannabis plants in their garden as soon as possible, they can remove the males ASAP, so they don’t interact with the females and ruin bud production. If a grower waits too long to identify the male and female plants, then they risk tarnishing the quality of their cannabis production.
Even growers who want male plants as part of their cannabis production should still identify which plants are male and which ones are female. Cannabis growers that use male plants to alter the strains of their cannabis need to identify which plants are male because neglecting to identify the sex will cause all of their female plants to produce low-quality buds. Male cannabis plants do not produce as high-quality buds as female cannabis plants.
Growers can identify the sex of their plants by the 6th week of their growth. Therefore, the pre-flowering stage is the earliest stage where growers can identify the sex of their cannabis plants. When growers identify the sex of their cannabis plants during the pre-flowering stage, they avoid wasting time and resources on unwanted male cannabis plants.
Growers should treat cannabis plants equally until they are sure of the sex of the plants. Unfortunately, if you do not have bred seeds, you have to go through the process of identifying the plants in the pre-flowering stage to ensure that you get high-quality buds. Unfortunately, there is no way to identify the sex of a cannabis plant from regular cannabis seeds and tell the pre-flowering stage.
Difference Between Male and Female Marijuana Plants in Pre-Flowering
Once your cannabis plant starts to grow pollen sacks, you can identify the sex of the plant. Identifying male and female plants before they blossom is crucial. Female plants will have stigmas during the pre, flowering stage, and milk plants will not. Male plants will also develop pollen sacs during the pre-flowering stage, and flower buds surround those pollen sacks.
It’ll be easier to distinguish between male and female cannabis plants as the plants get bigger. You will notice that male cannabis plants grow much quicker than female cannabis plants. Even though male plants go taller and faster, the buds they produce will not be nearly as high quality as the female plants. The fact that male plants produce lower quality buds than female plants is why most growers choose to eliminate male plants.
Knowing the difference between male and female plants during the pre-flowering stage is essential to the overall development of your cannabis plants. Neglecting to get rid of male plants early on can cause female plants to produce lower quality buds than they would otherwise.
Early Signs of Male Plant – Methods of Determining a Male Cannabis Plant? (100 words)
Male plants have more obvious tells in the pre-flowering stage than female plants. Just make small plants much easier to identify early on. The following are things to watch for when identifying male cannabis plants.
- During the pre-flowering stage, male cannabis plants will have pollen sacks that look like balls. Flowers will surround these pollen stacks during the pre-flowering stage.
- male cannabis plants grow much faster and taller than female cannabis. If you notice a cannabis plant shooting up above the other ones is most likely male.
- During the pre-flowering stage, male cannabis plants do not have stigmas. If you notice two thin hairs coming out of the bulbs of the plants, then the plant is female.
Early Signs of Female Cannabis Plant – Methods of Determining a Female Cannabis Plant
Female plants are highly sought after and vital to identify female plants early on in the growing process. The following are signs to look forward to identifying female cannabis plants during their pre-flowering stage.
- Females cannabis plants will grow stigmas during their preflower stage. To find the stigmas, you must look for the plant’s bulb and two thin hairs. Male plants will not have these thin hairs because male plants cannot grow stigmas.
- During the flowering stage, female plants will appear shorter than male plants, and you know plans will also not grow as quickly as male plants
Other Common Differences Between Male and Female Cannabis Plants
What’s the flowering stage arrives significantly easier to identify the difference between male and female cannabis plants. The most significant identifier between male and female cannabis plants is that female cannabis plants will produce buds, and male cannabis plants don’t produce any buds. However, it’s best to identify the plant before the flowering stage because if a male pollinator is female, the female produces lower-quality buds.
Male cannabis plants will also grow taller and faster than female cannabis plants. Shorter and slow-growing plants are most likely female. If you notice a plant that grows taller and faster than the other plants in your cannabis garden, it would be best to remove it because it is most likely male.
How to Treat Male Cannabis Plant?
As soon as you determine that your cannabis plant is male, you need to remove it from the female cannabis plants. Neglecting to separate female male cannabis plants will ruin the quality of the buds that your female plants produce. You can either eliminate the male cannabis plant or separate it from your other cannabis plants.
Some people keep male cannabis plants around to alternate the genetics of their cannabis plants. Other people repurpose male cannabis plants by chopping them up and turning them into mulch for other gardening purposes. However, the most important thing to do when you find out that you are growing a male cannabis plant is to isolate that cannabis plant from the female plants.
How to Tell the Difference Between Male & Female Plants (FAQ):
How do you tell if your plant is male or female early?
The female pre-flowers appear to have a pair of white hairs emerging from the center of a green calyx. They are longer in length, narrower in width, and have a wider base.
Male pre-flowers are distinguished from female pre-flowers by their spherical shape, diminutive size, and absence of trichomes, pistils, and hairs. Instead, they are shaped like spades, and as they mature, they become as small as the tip of your thumb.
When can you tell if your plant is male?
The male plant almost always grows taller than its female counterpart, and it also typically has stalks that are more robust and robust to sustain its weight. In addition, male plants have a smaller number of leaves than their female counterparts, which are typically more compact and bushy.
How can you tell if a seed is feminized?
The simple response to this question is that if all you have is a small collection of unlabeled seeds, it is extremely difficult, if not impossible, to determine which ones are male and which ones are female. Planting a seed and waiting for it to develop into a mature plant is the only way to accurately determine the gender of a plant.
When can a cannabis plant be sexed?
A cannabis plant will begin to show sexual characteristics in about six weeks. Growers can make greater use of their time, energy, and canopy space if they remove male cannabis or hemp plants before they flower.
Can a male weed plant turn into a female?
For several reasons, it is impossible to transform a male cannabis plant into a robust and healthy female. Firstly, it is impossible to distinguish actual males from the rest of the marijuana plants because most of them are hermaphrodites.
