Sexing Cannabis seeds has become a hot topic online, but there is no way of knowing if a cannabis seed is female or male by looking at it. Only when the marijuana plant starts to flower will you be able to tell the sex of a marijuana plant. However, there is a cannabis sexing seeds chart floating around on online.

How to Identify a Female Marijuana Seed

Ask any experienced grower how to produce a hardy marijuana plant and they will say to start with a seed for a good strain. Lighting, soil, nutrients, and water play large roles in the final yield, but starting with a high-quality seed gives growers the best genetics with the highest potential yield possible. Most people find their first seed mixed in with marijuana, but most of these seeds are low quality and may grow to be male plants. The best way to get high-quality seeds is to purchase them from a reputable marijuana seed retailer.

Characteristics of a Quality Marijuana Seed

Quality marijuana seeds have specific characteristics that set them apart. Unfortunately, they can be difficult for consumers to find since most growers avoid seed production in their plants at all costs. Even when a rogue seed is present, it rarely grows mature enough to germinate. Though it is challenging to identify a quality seed for even the most experienced growers, it is vital to be able to do so when using seeds to grow marijuana. Below is an overview of the characteristics of a high-quality seed.

Appearance

There are several visual indicators that can give a person an idea about the quality of a marijuana seed. Some details are easy to spot while others take a higher level of scrutiny.

Color

A high-quality marijuana seed has a dark color, typically a shade of brown, grey, or black. It should have tiger-like stripes or spots on the entire surface of the seed. If the seed is green or white, it is immature and is not likely to germinate. In the rare circumstance that an immature seed germinates, it takes much longer than it would for a mature seed.

Coating

Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.

Size & Shape

The largest seeds are the best ones to grow. It is easier to pick the largest ones if there are several to compare side by side. Growers should look for the most symmetrical seed that is round or shaped slightly like a teardrop. Underdeveloped seeds are small and have an asymmetrical shape.

A lot of information can be gleaned from the texture and hardness of a marijuana seed. After visually inspecting the seeds, growers can pick them up and feel their shell for the following:

Cracks

Poor quality seeds have weak shells that are damaged easily. These seeds will have cracks or splits on them that expose the inside. The best seeds have a smooth exterior with few anomalies.

Hard Shell

A mature, high-quality marijuana seed has a hard shell that can withstand the pressure of being squeezed between two fingers. Poor quality seeds will disintegrate when squeezed. If this happens, the seed was weak or dead and would not have grown a viable plant if it germinated at all.

How to Determine the Quality of a Marijuana Seed

While seeing and feeling a marijuana seed can give growers a lot of information, it is not always accurate. Even the best-looking seeds can be duds, especially if they have been frozen. Below are a few things growers can do to better determine the quality of their seeds.

Germinate the Seed

The most obvious thing a person can do to show seed quality is to germinate the seed. If the seed sprouts within 5 days, it is a viable seed. It will still take time to find out if the plant will be male or female and whether the strain is high quality.

How to Germinate a Marijuana Seed

The traditional way to germinate a seed is to bury it one-quarter inch deep in moist soil and watch it closely for a sprout. A freshly germinated seed has a very fragile root that is easily damaged when the seed is transplanted. This method allows the seed to germinate without root interference.

Another common way to germinate marijuana seeds is by wetting a folded paper towel or cotton pad and placing the seeds inside of it. It is important not to get the paper towel or cotton pad too wet or it could drown the seeds. Growers should check the seeds after a few days to see which have taken root.

Perform a Float Test

The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.

After the time has passed, seeds that float can be considered poor quality and discarded. Seeds that have sunk to the bottom of the glass are healthy, high-quality seeds. Once the test is complete, the seeds need to be germinated right away. Their shells will be soft from soaking in the water and will not survive storage.

Source Them Well

The simplest way for growers to ensure they have high-quality seeds is by sourcing them from a reputable seed bank. These companies specialize in breeding a variety of marijuana strains and producing seeds that, with the right care, grow into viable, high-yielding plants. Growers can choose a variety that meets their requirements for potency and desired effects and be sure they are getting seeds that produce the plant they want.

Using an Online Marijuana Seed Bank

Those who live in a state where marijuana is legal for medical or recreational use can sometimes find seeds at their local dispensary. However, online marijuana seed banks have significantly more strains available. Even individuals who live in some states where marijuana has not been made legal to use can purchase seeds online. Several states consider dormant seeds to be souvenirs, so it is legal to purchase and own the seeds as long as they don’t become high-THC plants.

Do Marijuana Seeds Expire?

Many growers who have numerous marijuana seeds need to store them long term if they want to germinate them in the future. However, seeds need to be kept in specific conditions to remain viable. They should be stored in a cool, dark, and dry room, much like the environment in which growers dry their harvested marijuana.

Germinating Old Seeds

Seeds can remain viable for three to ten years if stored properly, but more and more seeds will fail to germinate as time passes. Older seeds will take more time to germinate, so growers should use the float test before assuming the viability of their stored seeds. They can speed germination by soaking the viable seeds in water mixed with a few drops of hydrogen peroxide for 24 hours. It is important to watch them closely for signs of opening, as they will need to be removed immediately to avoid drowning.

Can You Tell if a Marijuana Seed is Female?

Cannabis enthusiasts have been trying to find out how to determine the sex of a marijuana plant by the seed for ages. Unfortunately, there is no way to tell if the seed will produce a male or female plant by just looking at the seed. Regular marijuana seeds have a 50% chance of being female, so out ten seeds, growers can expect that 5 of them will probably produce female plants.

What Does a Male Cannabis Plant Look Like?

When growing marijuana, it is important to identify male plants as early as possible. Just one male plant can pollinate an entire field, so it is critical that male plants are removed before they develop pollen sacs. There are certain signs that a young marijuana plant is male, including the following:

Preflowers

Preflowers are the earliest sign of a marijuana plant’s gender. Between four and six weeks, nodes will develop at the joint where a plant’s stem meets the stalk. Female plants develop white hairs at the internodal joints while male plants develop rounded internodal sacs that fill with pollen.

While it is best to identify male marijuana plants by their pollen sacs as soon as possible to avoid accidental pollination, there is another way to determine a plant’s sex. If male and female seeds are planted at the same time, the male plants will grow faster and taller than the female plants. Additionally, male plants have longer stems with fewer leaves, making them look spindly compared to female plants.

Final Thoughts

Quality seeds are not often found in the bottom of a bag of dried marijuana, but there are ways for growers to ensure they are getting the best seeds available. With a keen eye and a reputable seed bank like i49.net, growers will have hardy, high-yield plants that make them proud of their hard work. Seed banks provide quality marijuana seeds in a variety of strains not typically available from other sources, and many of them can guarantee that the seeds will be feminized and thus produce female plants.

    Sexing Cannabis: How to Tell the Difference Between Young Male vs Female Cannabis Plants

    Are you growing cannabis at home, but aren’t sure if your plants are male or female? Then you’ve come to the right place! This article is going to show you how to tell the difference between male and female cannabis plants to properly sex them.

    In particular, I want to show you how we determine the sex of our cannabis plants while they are still quite young. It gets significantly more obvious as the plants begin to mature and flower. On the other hand, it can be a bit more tricky to sex cannabis plants in the early pre-flower phase, but it is definitely possible! We’ll also talk a bit about why it is important to determine the sex of cannabis plants, the difference between regular and feminized seeds, how we treat our plants up until the time we know their sex, and what to do with unwanted male plants.

    If you’re new to Homestead and Chill, be sure to check out our other cannabis-related articles! We primarily grow outdoors, 100% organic, and aim to provide helpful information that is easy to follow – both for new and experienced growers alike. As a disclaimer, this article is intended for those who can legally grow cannabis at home.

    Feminized vs Regular Cannabis Seeds

    If you are growing from feminized seeds, you shouldn’t need to worry about sexing your cannabis plants all that much. While not 100% guaranteed, there is only a very slim chance that a feminized seed will produce a male plant. About 1% in fact. In all of our years growing, we have never had a cannabis plant grown from feminized seed turn out to be a male – though we only grow a handful of plants per year. Folks who grow hundreds of plants could potentially end with a rare male now and then.

    Feminized seeds are highly desirable to most growers. They’re efficient. It is almost sure-fire that you’re spending your energy and resources raising ladies. However, some growers accept or even prefer regular (unsexed) seeds! We grow a little of both.

    Why grow regular cannabis seeds? Well, maybe a particular breeder or strain you want to try only carries regular seeds. Some growers feel that the feminization process is unnatural, and prefer to kick it old school by growing regular seeds only. Some enjoy the gamble and challenge. Whatever the reason, when you grow cannabis from regular seeds, the odds of getting all lady plants are not in your favor. You will end up with some males. Therefore, you need to learn to sex your cannabis plants! Also, we always start several extra “regular” seeds – assuming a 50/50 chance that some will be culled because they are male.

    How are feminized cannabis seeds made?

    Curious about how feminized seeds are created? In a nutshell: most feminized seeds come from cannabis plants that have been treated and altered in a manner that inhibits male chromosomes. The most common method is to spray the plant repetitively (daily or more) with colloidal silver. Other chemicals and compounds can be used too, but are far less accessible. Colloidal silver is technically “non-toxic”, but you do not want to smoke it! Thus, the plant is sacrificial – used for the production of pollen and seeds only.

    Repeated colloidal silver treatments cause repression of the plant’s ethylene, which is the stuff that creates male flowers. Instead, the treated female plant will grow pollen sacks full of FEMALE pollen (XX rather than XY). Then breeders use the female pollen to pollinate female flowers, resulting in the development of all-female seeds.

    Another way to create feminized cannabis seeds is called rodelization. It is a more natural but unreliable method, and less frequently used by breeders. Near the end of a growing season, an un-pollinated female cannabis plant will sometimes produce pollen sacks in a desperate attempt to pollinate herself. That pollen can be used to try to create feminized seeds, but because ethylene hasn’t been repressed, may also result in male seeds.

    Okay, back to sexing cannabis.

    Why Sex Cannabis Plants? The Role of Male and Female Plants

    For the most part, the average home grower wants female cannabis plants. The ladies are the ones that produce the fattest, most resinous and most potent flowers – aka buds. Male cannabis plants are only desirable if someone wants to breed cannabis and save seeds (which is a whole other topic for another day). Even then, the grower will want to spot the difference between the male and female plants and separate them early on, unless they want free cross-breeding and pollination between many types of strains.

    Not only are the males less desirable, but male cannabis plants interfere with the quality and production of your female plant. Males grow pollen sacks, and produce pollen. When a female cannabis plant becomes pollinated by a nearby male, her energy shifts into producing seeds.

    Like most things in nature, female cannabis plants have a biological drive to reproduce. After the deed has been done, she will sit back and relax. While a pollinated female cannabis plant WILL still develop decent size buds, they are usually lower quality and contain less THC and other desirable cannabinoids. Not to mention, they’ll be full of seeds. When left un-pollinated, a female cannabis plant’s flowers (buds) will continue to swell, develop more trichomes and become increasingly resinous. She is trying to get as sticky and large as possible to catch pollen in the wind. That sweet sinsemilla – aka unfertilized, seed-free cannabis.

    When to Sex Cannabis Plants

    Our goal here today is to learn how to tell the difference between male and female cannabis plants early on, so you can get the males away from the females as soon as possible! It will help protect your lady plants – but also spare you the wasted time, resources, and energy of tending to male plants that you don’t intend to keep.

    Keeping in mind that every strain and grow set-up (e.g. indoors, outdoors, daylight hours) creates varying circumstances, most cannabis plants begin to pre-flower as early as 4 weeks after germination. By week 6, the pre-flowers begin to reveal their gender and you should be able to identify the sex using the tips to follow. Once the plants go into full flower (8 to 10 weeks on average, for a natural outdoor grow) the differences between male and female plants will be glaringly obvious. We’ll talk more about exactly what each sex looks like in a moment.

    Until we can tell the sex for sure, we continue to treat the plants equally. We start our seeds in small 4-inch nursery pots. About two weeks after germination, we pot the seedlings up into an approximately two-gallon (trade size) “sexing pot” like these BPA-free nursery pots. This enables everyone to continue to grow in a happy and healthy manner for several more weeks*. Then, once we can surely tell the difference between the male and female cannabis plants, only the ladies move into their forever home – 15 to 25 gallon grow bags full of recycled organic living soil. To learn more about our soil recipe and how we maintain it, see this article.

    *Note that our feminized seedlings go from a 4” pot to an 8” pot, and then more quickly into large grow bags, using less soil in the potting-up process.

    This little girl (or boy) is far too young to tell, but needs to be potted up soon. The two in plastic pots in the background were determined to be male and culled the next day. The two on the left in grow bags are definite females (one from feminized seed, and one we sexed from regular seed).

    How to Tell the Difference Between Male and Female Cannabis Plants in Pre-Flower

    In order to correctly sex cannabis plants, you’ll need to become familiar with their anatomy in general. Both males and females produce pre-flowers and flowers in the junctions between stems or branches. The very first pre-flowers show up in the crook between the main plant stalk and a fan leaf stem (petiole), usually near the top of the plant. The good news is, the males usually begin to develop and show sooner than females. I guess the idea is that the dudes want to have their pollen ready and waiting for when the ladies join the party?

    Look for plant pre-flowers at the higher stalk/branch junctions, as described above. If needed, use a jeweler’s loupe to get a better look! That is the same magnifying tool commonly used to examine trichomes and determine plant readiness for harvest. Then, locate the stipule, which is a leafy pointed flap that protrudes from the junction. Don’t confuse that for a pre-flower! The cannabis sex parts are located just behind the stipule. Behind the pre-flower sex parts, taller growth tips will emerge – future auxiliary branches that produce buds.

    Identifying a Male Cannabis Plant

    Very early, the male pre-flower (early pollen sacs) simply looks like a more round version than the female pre-flower part. It is often referred to as a “spade”, like the spade suit in cards – squatty with a bulbous bottom and very slight tip. As it becomes slightly larger, the male pre-flower resembles a ball at the end of a stick. The male pre-flower is called a staminate. Then, the staminate eventually develops into a long hanging sack of baby bananas – the pollen sacs. Hopefully you can ID and cull the males before they get to this stage.

    Identifying a Female Cannabis Plant

    In contrast, the very early female cannabis pre-flowers are more ovate in shape: pear-like, but with a longer slender pointed tip. That is called her calyx. Extending from the tip of the calyx may be a pair of pistils, or white hair-like protrusions. However, please note that not every female cannabis plant in pre-flower produces pistils.

    If you are still unsure of the sex of your cannabis plant, wait to make any drastic decisions! Yet if you’re fairly certain, consider some of these other common differences between male and female plants. Perhaps it will help you more confidently make a decision.

    Other Common Differences Between Male and Female Cannabis Plants

    Aside from the clear-cut flower differences, there are a few (potential) trending characteristics between male and female cannabis plants. In many cases, male cannabis plants tend to be more gangly. They may be tall, narrow, have fewer fan leaves, and longer spacing between branches – also referred to as greater inter-nodal spacing. On the flip side, female cannabis plants are usually more compact and bushy than males.

    Please keep in mind that these traits are not guaranteed, and shouldn’t be the only way to sex cannabis plants! Variations among strains and phenotypes can lead to all sorts of crazy things. The general plant structure simply may help give you a clue if you’re on the fence.

    My Cannabis Plant is Male! Now What?

    I hope you started a few extra seeds, and have plenty of ladies left to grow! Once you determine that you have a male cannabis plant, get rid of it. Again, unless you want pollination and seeds, it is best to cull the males as early as possible. Simply separating the plants isn’t enough. Even if you relocate the male plant to another part of your yard, the pollen can carry in the wind. There are stories of female cannabis plants becoming pollinated from neighbors growing several blocks away.

    However, the culled males don’t need to go to waste! One option is to chop up the male plant and use it to mulch other plants – much like we do with borage, fava bean greens, yarrow, and comfrey. You could also juice the leaves, which are full of nutrients. Heck, you could even steep the plant material in water to create a natural fertilizer as we do with stinging nettle. Finally, I’m sure your compost pile will welcome the male plant with open arms. Or would that be… with open worms?

    Can You Tell the Sex of Cannabis Seeds from Their Appearance

    Of all the things that can trip a grower up, sexing marijuana plants may just be the trickiest. Sexing plants is so important because growers are typically after the female plants, that produce the huge THC covered buds. Or the medicinal relief that CBD strains can bring. With such opposite effects of male and female plants, it’s easy to see just how important sexing plants is. But what if growers didn’t have to wait to sex their plants? While it would certainly make life easier, is sexing cannabis seeds possible?

    Can you determine the sex of cannabis seeds?

    This has been a question that has become a very hot topic online these days. After a quick search, growers can find multiple charts and explanations on how to sex cannabis seeds.

    Unfortunately, there’s not much truth to any of these interpretations. It’s simply impossible to tell just by looking at them what the sex of any cannabis seed is. If it was that easy, feminized marijuana seeds would not be as popular as they are. People could simply buy regular seeds and look at them themselves.

    Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.

    So where do all the myths from sexing cannabis seeds come from?

    Common myths on identifying the sex of a cannabis seed

    One of the biggest myths of sexing cannabis seeds comes from a popular chart online.

    The chart states that one can determine the sex of a cannabis seed by just looking at them. Within the chart, five cannabis seeds are shown. Three of these are female and two are male, supposedly. This chart says to look for a crater at the bottom of the seed. It explains that females will have a depression that is perfectly round. While males will have a crater that is misshapen and not uniform. However, this is simply not true. The craters found in cannabis seeds have nothing to do with the sex of a seed.

    This same chart states that females will also roll easily across a table or surface, while males will not. While it does say that a magnifying glass and pair of tweezers is needed to examine the seeds. neither of these tools will make it any easier to determine the sex of cannabis seeds.

    While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.

    Environment determines sex debate

    We know that determining the sex of cannabis seeds cannot be done. However, it’s unclear as to whether environmental factors have any place in determining the sex of marijuana plants.

    Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.

    While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.

    This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.

    Growers know that hermaphrodite plants can be just as harmful to crops as male plants. Therefore, it’s very important that every grower understand how to sex marijuana plants. Particularly if they’re not using feminized marijuana seeds that will give them only females.

    While it would be much easier for growers to be able to sex their cannabis seeds, the simple fact is that there’s no way to do it. However, sexing plants early on during their growth period is not only essential, it’s completely possible. Growers can even do it before their plants enter the flowering stage if needed. Then male plants can be removed and growers can enjoy a nice, full crop.
