Cannabis seeds 101: How to grow marijuana from seed

Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.

In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.

If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.

Cannabis seeds vs. clones

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.

If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.

Most seeds that you will buy are regular seeds as described above, but here are a couple more types.

How weed seeds work

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.

To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”

Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.

How weed clones work

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Pros and cons of using cannabis clones

Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.

With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.

One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.

Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

Additionally, every long-time grower will tell you that clones degrade over time.

What are feminized cannabis seeds?

Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.

This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:

  • By spraying the plant with a solution of colloidal silver, a liquid containing tiny particles of silver
  • Through a method known as rodelization, in which a female plant pushed past maturity can pollinate another female
  • Spraying seeds with gibberellic acid, a hormone that triggers germination (this is much less common)

Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.

Top feminized cannabis strain families

A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:

  • OG Kush
  • Haze
  • Afghan
  • GSC (Cookies)
  • Skunk
  • Cheese
  • Gelato

What are autoflowering cannabis seeds?

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Pros and cons of growing autoflower

Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.

A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.

However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

Tips for growing autoflower marijuana seeds

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.

Climate considerations

Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.

Training plants

Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.

Go easy on nutrients

Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.

What are high-CBD cannabis seeds?

CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).

Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.

How to germinate marijuana seeds

Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:

  • Two clean plates
  • Four paper towels
  • Seeds
  • Distilled water

Step 1

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Step 2

Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.

Step 3

To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.

Step 4

Make sure the area the seeds are in is warm, somewhere between 70-85°F.

After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.

Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.

A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

Transplanting germinated cannabis seeds

Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.

  • Fill a 4-inch or one-gallon pot with loose, airy potting soil
  • Water the soil before you put the seed in; it should be wet but not drenched
  • Poke a hole in the soil with a pen or pencil—the rule of thumb is: make the hole twice as deep as the seed is wide
  • Using a pair of tweezers, gently place the seed in the hole with the taproot facing down
  • Lightly cover it with soil

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Within a week or so you should see a seedling begin to grow from the soil.

Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.

This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.

How to sex a pot plant

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.

Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.

Can I grow a seed I found in a bag of weed?

Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.

These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.

Is a bagseed good or bad?

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.

So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.

Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.

Was the seed found in good weed?

If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.

Are you ready to grow?

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Is the seed viable?

For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.

There are a few indicators that will give you a sense of whether the seed is worth germinating.

  • Tiger stripes—dark stripes on the seed which resemble veins on a leaf are generally good
  • Solid shell—a seed should be able to withstand a little pressure when pinched between your fingers; if it crumbles or cracks, it’s no good

Immature seeds tend to be light in color and have a soft outer shell.

In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.

You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.

But if the seed you found looks decent, you might as well germinate it and see what sprouts.

Time to germinate

Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.

If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.

Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.

Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.

How to buy cannabis seeds

Cannabis seeds can be found on numerous online seed banks, but note that it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In legal and medical states, you may purchase seeds at a dispensary.

Do Feminized Cannabis Seeds Make Hermies?

What Are Feminized Cannabis Seeds? These seeds all grow up to be female plants. That means every plant produces buds. With “regular” or unfeminized seeds, about half the plants will turn out to be male, which don’t produce buds. They can also pollinate your female plants (causing seedy buds). Therefore most growers will remove male plants from the grow room as soon as they’re identified. Learn more about male vs female plants. Feminized seeds let you plan your grow more effectively because you don’t have to throw half the plants away once they start flowering.

Every plant grown from feminized seeds will produce the buds we know and love. This plant was grown from feminized Swiss Cheese seeds.

What Are Hermies? “Hermie” is short for “hermaphrodite.” Hermie cannabis plants usually look like normal female plants for the most part, but they also grow some male parts that produce pollen. This causes seedy buds just like pollen from male plants. Hermies are to be avoided! Read the full tutorial on hermies.

It’s no good if your “female” plants start growing male flowers or parts of male flowers. That can cause seedy buds just like a male plant!

An example of a male hermie banana growing on a (mostly) female marijuana plant in the flowering stage.

This bud got completely seeded due to a hermie in the grow space. Notice the lumpy round bits. Those are seeds forming.

What’s the matter with a few seeds?

Cannabis growers are trying to grow sinsemilla (seedless buds). A few seeds won’t hurt anything. But if you have very seedy buds, it significantly lowers your yields because plants are putting all their energy into making seeds. The buds also tend to be less potent if they are full of seeds. Seeds are not the end of the world, but it’s good to avoid if possible.

“Sinsemilla” means “no seeds.” Sinsemilla is the highest quality and most potent of all buds

In order to grow seedless buds, it

Since most growers are trying to grow sinsemilla, having only 100% female plants in the flowering grow room is crucial to prevent pollination.

Feminized cannabis seeds can be a blessing for small-scale growers. While male plants produce pollen sacs, feminized seeds ensure all your plants will end up being bud-bearing females (instead of growing half male and half female plants like with regular seeds).

If you don’t have room for extra plants, feminized seeds can make planning your grow a lot easier!

Closeup of feminized cannabis seeds

Good feminized seeds should produce only 100% female plants, with no hermies or male plants. So starting with feminized cannabis seeds lets you make the most efficient use of your grow space. You don’t have to worry about identifying male plants and throwing them away before they pollinate your female plants. With good feminized seeds, you know that if you’re growing 10 plants, all 10 of them will make buds, and that makes it easier to plan out your grow ahead of time.

With all these bonuses, why would any small-scale grower use any other type of seeds?

Pros of Feminized Cannabis Seeds

All plants produce buds

You don’t have to throw away half your plants after nurturing them for weeks

You don’t have to worry about your buds getting pollinated, causing seedy buds, reduced bud quality and lower yields

But is there a dark side to feminized cannabis seeds?

One of the biggest worries growers have about feminized seeds is that they will produce hermies instead of 100% female plants as advertised.

This hermie is growing both male and female flowers. Can this be caused by feminized seeds?

A hermie cannabis plant with both male and female parts, this plant has pollen sacs growing in the same place as female pistils

Unfortunately, hermies can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s affected. A male plant makes itself known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs. A few yellow hermie bananas hidden in the buds can also produce pollen. Any type of male flower part that grows in your garden can add seeds to your buds, and hermies are some of the worst offenders.

This grower didn’t notice that the buds had been seeded until harvest. As he was trimming, he noticed seeds popping out. Since there were no male plants, chances are this was caused by an unnoticed hermie somewhere in the grow space.

Seedy buds with calyxes popping open everywhere

Is it True that Feminized Seeds Sometimes Cause Hermies? Yes!

Many growers believe that feminized seeds can cause hermies, and there is some truth to that. In order to create a feminized seed, one of the parent female plants had to be forced in some way to produce pollen.

That pollen is used to pollinate another female plant, and the offspring of those two plants will all be female since both of the parents were female. That’s how you get feminized cannabis seeds. But that also means every time you have a feminized seed, that seed had a plant that produced male flowers in its recent genetic history.

There are different ways to feminize seeds, but only some methods produce seeds that turn hermie on you.

It’s important to understand that hermies can happen a couple of different ways. And the different types of hermies affect what genes are being passed on to the seeds.

What Causes Hermies?

Hermies can be caused by many things, including…

bad genetics – the plant comes from a line of plants that naturally create hermies for no reason, even in good growing conditions

high stress – high temperatures, light leaks, inconsistent light schedules, as well as other types of major stress can cause a healthy plant to hermie, though some plants/strains are more susceptible than others

letting buds over-mature – this is also known as “rodelization;” basically when the plant’s buds have gone past maturity without being pollinated (if the grower waits way too long to harvest), a female plant may make male pollen within its buds as a last ditch effort to pollinate itself and make seeds for the next generation

chemical stimulation – by exposing a female plant to certain substances like colloidal silver or gibberellic acid during the early parts of the flowering stage, you can force any female plant to create pollen. This is how seedbanks get female pollen to produce feminized seeds.

Seeds created from “female” pollen will turn out being female (or at least as female as the parents).

The pollen from a hermie plant makes feminized seeds

The pollen sacs on this masculinized female plant have opened and pollen has spilled onto the leaf below

Example of a male marijuana plant spilling pollen onto a nearby leaf

Another type of hermie: a yellow “banana” can appear in your buds and make pollen. This male flower part would normally be inside a pollen sac. When it’s in the open like this, it becomes a little pollen generator.

Buy seeds from good breeders to avoid cannabis hermies

Feminized seeds are susceptible to becoming hermies themselves when exposed to the same conditions as their female “father” who produced the pollen. But since any plant can be chemically induced to produce pollen, it doesn’t mean that the ability to hermie in a natural environment is passed on to the seeds.

So only some feminized seeds come from parents with bad genetics, and that’s what’s the grower cares about most.

The bagseed gamble… When you find seeds in your buds, that usually means that the buds were pollinated by accident. Seeds that were accidentally created are suspect. It could be that a stray male plant caused them, which means there were no hermies and you will get about half male and half female plants. But accidental seeds could also be the result of herming by an indiscriminate grower, and that means you have feminized seeds, sort of. Some of them may produce pollen on you just like their parents. Growing with bagseed is a big gamble… you never know what you’re going to get.

Are your cannabis bagseeds viable? Viable, good seeds usually appear either dark and striped or solid gray/beige.

Cannabis seeds can look a couple different ways - they can be dark and striped, or solid gray/beige

If a seed is pure white it usually means it’s underdeveloped and won’t sprout. But it can sometimes be hard to tell. In the end, if a seed sprouts and grows it’s a viable seed! I’ve had very pale, flimsy seeds sprout into gorgeous fast-growing plants, so if you’re not sure the best thing to do is try to germinate it!

Seed Banks & Breeders

Commercial breeders and seed banks use chemical stimulation to create feminized seeds. What that means is they put specific compounds on developing female plants to force them to produce pollen. You can actually do this yourself at home.

This technique works on nearly any female plant, including plants that would never hermie naturally. So it can be used to take two plants with great genetics to produce female seeds. But the same process will also work incredibly well on plants that do hermie easily all on their own. That means it’s up to the breeder to test and make sure that they have a solid plant with unbeatable genetics before using the feminization technique.

The pollen that results from chemical stimulation is used to pollinate another female plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation, then you have created feminized seeds that won’t ever make pollen in your grow room.

But if one of the parent plants was chosen because it does hermie easily, you’ll end up with seeds that likely will herm. The breeder might not have done any testing on the parents or the resulting offspring to even know.

Without testing, a breeder can’t tell whether they’ve created quality feminized seeds

You want to get seeds from a trustworthy breeder in order to avoid cannabis sex problems ;)

Choosing the Right Cannabis Breeder

Unfortunately, some cannabis seed breeders are more trustworthy than others. The great ones have created stabilized strains that have been bred over several generations to produce a consistent product without any problems with plant sex.

Less scrupulous breeders might breed two random female plants together and sell the resulting seeds as a new strain without any testing. In this second case, you don’t know what to expect, and neither does the breeder.

If the breeder hasn’t tested their strains extensively in many situations, they won’t know whether their seeds tend to hermie or not. If they have carelessly bred plants that have a tendency to herm, then it’s really likely that at least some of the resulting seeds will have the same problem.

Breeder choice is important!

A cannabis cola - strain is Girl Scout Cookies

I have to admit I may be biased towards feminized seeds. I’ve grown almost exclusively with feminized seeds over the last decade. It has made my life so much easier! I only purchase seeds from breeders that I trust and all the resulting seeds have been bud-bearing females. I haven’t had any real problems with hermies.

On the flip side, I’ve heard of growers buying feminized seeds from untrustworthy breeders and having a big portion of their seeds turn male or become hermies even in perfect growing conditions. So there is truth to the fact that you can run into hermie problems with feminized seeds.

Yet there are good and bad breeders out there, and with good breeders, you have a very low chance of running into cannabis sex problems.

So if you do choose to purchase feminized seeds (or any seeds really), please make sure you get them from a trusted breeder!

Conclusion: Feminized seeds from a trustworthy breeder have a low chance of producing hermies, but the odds are much worse with feminized seeds from an untrustworthy source

The truth is it takes a hermie of some sort to create feminized seeds. That means that you always run the risk of running into hermies when growing feminized seeds… yet that is true for non-feminized cannabis seeds, too! Lots of regular seeds produce hermies.

What’s most important, whether you get feminized seeds or not, is to get your seeds from a breeder who has a reputation for producing quality genetics. That is the best thing you can do for any strain to ensure a smooth grow. With a great breeder, you have a very low risk of running into any sex or gender problems.

I personally prefer feminized seeds, and that’s the only type of seed I grow. It makes it easier for me in my limited grow space. I haven’t run into any significant problems with hermies, so I’m satisfied with growing only bud-bearing plants.

Yet a lot of growers grow with regular seeds because they’re easier to breed and produce at home. Many growers have created a system for weeding out male plants that is more convenient for them than using feminized seeds.

In the end, when it comes to feminized cannabis seeds you need to decide whether the small chance for hermies is worth the convenience of all-female plants. It’s up to you to figure out what’s best for your needs!

"Hermie" cannabis plants can look like normal female plants at first glance, but they produce pollen that causes seedy buds. Hermies are to be avoided!"
