The difference between regular and feminized cannabis seeds – Which should you grow?
With the general hype surrounding the relatively recent developments of feminized and autoflowering seeds, you’d be forgiven for maybe thinking that regular cannabis seeds are somehow less exciting. You’d also be wrong. Regular seeds contain endless possibilities for growers to experiment with.
In the beginning of Sensi Seeds, and therefore the European cannabis seed industry, a seed was a seed. Now, we use the name ‘regular cannabis seeds’ to distinguish the originals from feminized cannabis seeds and autoflowering cannabis seeds. Both of these types are relatively recent developments when you consider that cannabis has been cultivated by humans for thousands of years.
Regular cannabis seeds are produced when a male cannabis plant pollinates a female cannabis plant. Male pollen is released from ripe pollen sacs and blown by the wind (or carried by the careful hand of a breeder) until it finds the receptive stigmas in female flowers. Pollination results in hundreds, if not thousands, more regular cannabis seeds which will all in turn produce either male or female cannabis plants.
Can you see the difference between regular and feminized cannabis seeds?
Feminized cannabis seeds look exactly the same as regular cannabis seeds, whether male or female. But inside their modest brown husks there’s a crucial difference. Feminized cannabis seeds lack male chromosomes, whereas regular cannabis seeds contain the full complement of genetics that enable them to be either male or female.
This is also why feminized seeds must always be referred to by that name – they aren’t truly female, and therefore cannot be sold as such. Watch out for seeds described as ‘100% female’, as this is nothing more than a marketing ploy!
The main advantage for growers who choose feminized cannabis seeds is that they don’t have to identify or remove male plants which would cause pollination. Unless the gardener desires more seeds, rather than buds, this is an essential part of the cultivation process.
Automatic, or autoflowering, cannabis seeds are even easier. Not only are they feminized, they do not rely on a change in lighting cycles to trigger flowering. So what are the advantages of regular cannabis seeds?
The Difference Between Craft and Commercial Cannabis, And Why You Need to Know
What are regular cannabis seeds used for?
There are two main purposes for regular cannabis seeds, aside from the usual and most common one of simply growing buds.
- The first is breeding. Selective crossings of one cultivar with another has been taking place since the earliest days of agriculture, with all types of plant life. Sometimes this is to maximise the yield of whatever crop the plant produces which is desired by the people growing it; sometimes it’s just for fun and experimentation.
Whatever the intention of the breeding is, it’s best to begin with all the genetic material in order to give the new cross the best possible chance of success, rather than missing the chromosomes that are absent in feminized cannabis seeds.
- The second use for regular cannabis seeds is the one that was, before the advent of feminized seeds, most commonly used to produce crops of uniform cannabis plants without any males among them. This technique is called cloning. Just as with breeding, it’s best done with plants that have their full set of chromosomes, and all the robust qualities that go with that.
From a crop grown from regular cannabis seeds, the best female plants are selected to become ‘mothers’ – so called because with loving care, they can produce potentially hundreds of ‘children’ over the space of several years. The clones that are taken from these mother plants are tiny replicas down to the last scrap of genetic material – including their female sex.
Why do Sensi Seeds still produce regular cannabis seeds?
There are many seedbanks which only carry feminized cannabis seeds. This has become more common as seedbanks themselves have become more common. With the growing awareness (pun intended) of the advantages of feminized seeds, the question of why Sensi Seeds still carries regular cannabis seeds is quite a reasonable one!
The overall answer is simple, and one which anyone familiar with Sensi Seeds will probably have heard before: we want to bring the joy of cannabis to as many people as possible. That’s not limited to simply selling seeds.
We’re confident in our genetics, we’re confident in our service, and we’re confident in our customers. That means giving everyone the broadest range of options possible. This could be taking the simplest route to a crop of buds, which for most people is automatic seeds. But it could be experimenting with creating a unique cross of their very own, using our genetics as the building blocks.
We have quite often been asked if it’s possible to do all the things that can be done with regular cannabis seeds using feminized seeds.
The short answer is, you can try. There’s no reason you shouldn’t attempt to breed, or create a mother plant, using feminized cannabis seeds. However, it’s our firm belief that these practices are more likely to succeed using plants grown from regular cannabis seeds.

I’m a newbie at this – and I’m growing a few different plants.
I am having a blast with all of this fun stuff –
I didn’t know anything about seeds females/ males or feminized and auto flowering until this year.
But I am really enjoying this adventure.
I really like and appreciate your posts and blog for learning new things about all of the different seeds and processing/ cultivation. You have given me some good info and great explanations on the differences between regular and all other seeds – which is definitely good info for a newbie thank you
Thanks for your comment and your feedback.
I’m so pleased you are finding the blog educational, and having a blast learning!
Please check out the following articles which I think you may find of use, and I hope you continue to enjoy the blog!
With best wishes,
Good day hooter heads from around the world from Australia,due to the economic climate from covd & most govt recognising the money in pot,we won’t have to go to such length,s sneaking about like outcasts,the med uses for this versatile plant have saved the day,the war on drugs is a hoax,if it wasn’t the hard drug crops Afghan, Thailand opium would of been eradicated,like south America,s coke industry..I think govt,big corp are scammers.
I like feminized seeds but I have used regular seeds and they both grow just as well and have the same potency. Some people like feminized over regular seeds but it doesn’t make a difference except that you might get a male instead of a female but you can use that male to get hundreds more seeds and cross breed them with other plants and get different types of plants. Thank You.
For breeding for the rare Cannabinoids you really need to use selfing like is used for feminized seed production. I speak from experience being the very first to commercialize using STS, I did not make and sell feminized seeds I bred varieties that had a single Cannabinoid, for each of the less common Cannabinoids, like CBC, CBG, THCV, CBDV, CBCV, CBGV each in very high amounts and with close to zero other Cannabinoids. This can not be done with regular seed breeding. And male genes as found in regular seeds do not produce better plants for growing or breeding, I think maybe you do not understand plant genetics for Cannabis which is a Dioecious obligate outcrosser.
Why no mention of hermaphroditism? That is not only How you breed then but ultimately also the biggest flaw and why producing fems is really polluting the gene pool.
Hermaphroditism should be a recissive gene, but your breeding requires it to be a dominant trait. It’s like finding people with dodgy heart conditions or baldness (typical recessive traits that can skip generations) breeding them so everyone goes bald and has a bad heart.
But hey the market wants what the market so u gotta sell what people buy.
This article is intended for our readers who are new to cannabis seeds and, as the title says, focuses on the difference in results rather than the difference in the techniques that produce the seeds. In previous decades, creating feminized seeds was indeed reliant on finding lines with pronounced hermaphroditic tendencies, but thanks to improvements in breeding technology this is no longer the case.
With best wishes,
Improvements? like what? using silverfiosulphate instead of gibberalic acid?
Im not familiar with this “new” technique that does not require one parent to be hermaphrodite….I read arjens blog but that explains even less.
what exactly is this new technique? how does one create fem seeds without hermies?
FYI selecting strains more resistant to hermie, that require excessive amounts of stress to turn, is not new.
No. the disparition of regular seeds would be a disaster and I don’t understand the Auto flowering for me it’s a non sense, it is my personal opinion.
Fear not, we have no intention of removing regular seeds from our catalogue; they are the backbone of our gene library! Regarding our autoflowering strains, they are of great benefit to people who have limited resources in terms of time, energy, experience, and / or space, for whom cultivating regular or even feminized seeds would be out of reach.
With best wishes,
why dont you sell seeds in Canada.
Thanks for your comment. Unfortunately, legal restrictions on exporting cannabis seeds mean that they cannot be sent to Canada; we wish it wasn’t so, but it is!
With best wishes,
I believe regular seeds Are The seeds. Feminidad and autoflowering Are productos Or decides to Get Buds.
My blessings to tour effort and hope one Day I Will ser My seed baño with My full range Of seeds. We need The cannacopea.
I to agree with the good parts of regular seeds. Also your buds are generally bigger too. Once you have a selection of females it’s time to CLONE!! More fun !
Then one more fun thing is to develop your own breed! Cross your favorite.
I’m just sad you don’t sell to the U.S.. If you change your mind if like to show you some of my cross breeding. And to acquire more seed stocks. Having fun is most important.
Thank you for your comment We wish that our seeds could be sent to the US, but legal restrictions prevent this – as soon as this situation changes, our policies will change too! In the meantime, I hope that you continue to enjoy the blog.

Long Live Regular Photo Period Seeds.
Did I catch a recommendation to use only reg seeds for a Mother? Please explain. Ive been growing out a FPOG Mother from fem seeds. Will she clone out ok?
Thanks Y’all. 1LUV

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.
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.
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.
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:
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.
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 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.
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.

Can You Tell if a Cannabis Seed is Male or Female?
W hen it comes to growing cannabis, sex is important. Not that kind of sex! We’re talking about the sex of the plant, and whether it is male or female. The reason for this is simple enough: only female seeds produce flower, also known as the buds you might have in your stash as we speak.
- Cannabis Seeds Explained
- What to Look for When Buying Cannabis Seeds
- How to Germinate a Bag Seed
- Understanding the Anatomy of a Cannabis Plant
Cannabis seeds can be male, female or hermaphrodites. Females produce the resin-secreting flower, and males make small sacs of pollen near the base of the leaves. Over the years, cultivators have learned that un-pollinated females (remember, males produce pollen) continue to make resin as they grow, and flowers that have not been pollinated are much more likely to produce high-potency cannabis. This is the basis of all modern medical and recreational cannabis cultivation, so determining the sex of a plant is highly important. But is there a way to know if a seed is female before growing?

- How Important is Your Plant’s Sex?
Determining if a Cannabis Seed Is Male or Female
The straightforward answer is that, if what you’ve got is a handful of unmarked seeds, it’s pretty much impossible to tell which ones are male or female. The only true way to tell the plant’s gender is to plant a seed, then wait for it to mature.
After a period of several weeks, the plant will begin to pre-flower, or form a small bud in the crux of a branch. One of the first signs your cannabis plant is female is the appearance of pistillates that are wispy and generally white in color. Male plants will instead produce pollen sacs that look rounded with distinct splits running lengthwise, a bit like a tiny crab claw. These are the structures that growers typically look for to determine a plant’s sex.
If you’re looking for more precise, science-based methods to tell your plant’s gender, there are several labs that can sex your plant right after germination – eliminating the lengthy (usually around 6 weeks) wait to learn its gender. Portland, Oregon start-up Phylos Bioscience is in the business of studying cannabis genetics, and they sell a “plant sex kit” that’s pretty simple to do, even for the folks that aren’t scientifically inclined. Simply press a cotyledon, or embryonic leaf, onto the kit’s filter paper and send it to their lab. They then test the leaf for the “Y” chromosome to determine its gender, just as would happen for a human male.
What Are Feminized Cannabis Seeds?
While it’s basically not possible to determine the sex of a seed from a random bag of seeds, a practice known as feminizing is quite popular. Feminized seeds are selectively bred to produce only female plants.
While the process is very effective, it’s not perfect. There’s a chance that a small fraction of the seeds produced via the feminization method will sprout hermaphrodites, which are still capable of producing pollen.
Despite the potential for ‘hermies,’ knowing your seeds are female from the beginning is probably your best bet.
There are many companies that sell feminized seeds, but buyer beware, do your research to make sure the seller is reputable, especially if purchasing online. Thanks to modern technology, most feminized seeds from reliable brands will be 100% female as advertised – but that doesn’t mean there aren’t people selling low-quality seeds out there.
Methods for Feminizing Cannabis Plants
If you have some experience growing cannabis and would like to bend a crop to your will to ensure that the seeds will be female, there are a few feminizing methods you might try. One such technique is to literally stress out a healthy female plant by interrupting the light cycle during flowering, called Rodelization Feminizing.
In the colloidal silver feminizing method, distilled water is mixed with pure silver and sprayed on female plants. This method works best when the plants are flowering. This results in pollen sacs being formed, which will allow the seeds to produce female plants.
Feminizing via the silver thiosulfate technique involves carefully selecting a nearly mature female plant, then spraying it with a 50/50 mix of sodium thiosulfate and silver nitrate. This triggers a gender change, from female to male. Place this plant back with the others to pollinate other female plants, and female seeds are created.
Separating Male and Female Cannabis Plants
As anyone with seasonal allergies can attest, it only takes a little bit of pollen to have a big impact. The reason that growers are so intent on weeding out male cannabis plants is that a single pollinator can negate an entire potential harvest.
How? The reason is that once pollinated, cannabis plants will cease devoting energy to growing flowers and will tell the existing flowers to stop producing resin, which translates to making less buds and less THC. That energy will be devoted to producing seeds instead. Think of the plant as a battery with a set amount of power. When that supply is spent in one area, it won’t be available for another.
Now consider that a single male plant can spread its pollen to an entire room of females.
If a grow is accidentally pollinated, that means the resources that were spent to bring the plants to that stage — the water, soil, electricity, fertilizers, not to mention the price of the seeds themselves — will have been wasted growing weed that can’t be smoked.
All of those male plants will have to be carefully separated from the grow space and destroyed, or else the growers risk another disastrous accidental pollination. It takes minuscule amounts of pollen to pollinate a plant, so growers must take extensive precautions to eliminate potential contamination. In addition to helping mitigate other contaminants, this is one of the main reasons that many workers will don full-body suits when working in a grow room, ensuring that accidental pollen exposure is kept to a minimum.
How Important is Your Plant’s sex?
How much time you want to spend figuring out the sex of your cannabis plants really depends on how much time and energy you’d like to devote to growing your own marijuana. If you are a medical cannabis patient or caregiver, for example, and need to know what kind of cannabis you are getting every time to keep a reliable supply, buying feminized seeds from a trusted seller is the way to go. It may even be worth it to have your plants tested for sex before they mature. However, if you have some time, consider yourself a green thumb, and want to experiment with your grow, you could simply plant your seeds and see what comes up. Happy growing!
