Feminized Seeds Explained: Let’s Separate Fact from Fiction
What is a feminised weed seed? We try to answer this question and clear some of the misconceptions that even seasoned growers have
Today, feminized seeds are everywhere. You can grow weed for years without actually laying your eyes on anything else. As if marijuana were a single sex (female) plant all along. But it isn’t so, and it’s best to have clear answers to the following questions about feminized seeds: what does it mean and what exactly to expect from them? These questions are not just theoretical, but have a real practical value.

What is a Feminised Weed Seed Exactly?
Here’s a very short and pragmatic feminized seeds definition for you. Feminized seeds are cannabis seeds that turn into female plants only. This is how they differ from regular seeds which can turn either female or male. Now let’s talk about it in more detail.
As you may know, cannabis has two distinct sexes. Take a bunch of seeds from plants grown in nature and sow them. Some of them will grow into male plants and some — into female plants. The ratio will be around 50/50. Growers call such natural seeds regular.
For some time, regular seeds were all that was available to weed growers. The first small batches of seeds that deserved the name ‘feminized’ started to appear in the beginning of 1990s in Amsterdam. It was the founder of Dutch Passion who first offered them. Today, Dutch Passion is one of the oldest commercial seed banks that are still around.
The feature of this new type of seeds was that they grew into female plants more than 95% of the time. In fact, closer to 100%. It was a God’s gift for bud growers because now they didn’t have to throw away half of their plants at the beginning of the flowering. They knew that there would be only females in their garden and that they would harvest buds from every seed they had sowed.
Are Feminised Seeds Always Female?
Well, ideally they should be, and serious breeders go to great lengths to ensure that ALL their feminized seeds become female, but in reality they never are. Not 100%. Even the best feminized seeds produce males occasionally. Fortunately, such occasions are rare. Statistically speaking, you should grow close to a hundred of plants before you see a male intruder in an all-girl team. So can feminised seeds turn male? Yes, they can, but it’s highly unlikely for you to have this issue with your very first attempt.
What Makes a Feminised Seed?
The feminized seeds definition we’ve given above doesn’t explain how exactly breeders manipulate the beans into producing only females. In a few words, cannabis plants can change their sex in response to stress or when exposed to certain chemicals. It means that females can turn into males and produce pollen sacks instead of flowers.
Growers have long noticed this phenomenon. It’s called hermaphroditism and is a very unwelcome thing in your garden because you want buds without seeds and ‘female’ pollen will make all the buds go to seed and your whole crop will be ruined.
So, growers had been fighting ‘hermies’ for a long time, but they didn’t immediately realize that the seeds that they got in their buds because of female pollen would grow into female plants only. Well, hermaphrodite plants to be exact. Meaning that they will mostly produce female buds, but also some pollen sacks whenever they experience too much stress.
Believe it or not, the very first batches of feminised seeds marketed by Dutch Passion in the early 90s were made exactly this way. The plants were stressed to the point that they hermied and then hermies-prone seeds were harvested and sold. No wonder that those initial barbaric methods gave feminized seeds a bad reputation and still make some purists use only regular beans. You can read more about ‘feminised seeds vs regular’ controversy in a separate post.
Feminized Seeds Without Hermies Are the New Norm
The time when ‘fems’ and ‘hermies’ were practically synonyms is long gone. Now, breeders produce feminised seeds in a totally different way. They use special chemicals for this. It could be gibberellic acid or silver thiosulfate or such a simple solution as colloidal silver water made with the use of a homemade 9V battery feminisation kit. Anyway, none of these techniques involves any stress. It means that the resulting seeds are no more prone to hermies than their regular counterparts.
There is even a special method to make sure that a plant you choose for making feminized seeds isn’t predisposed to hermies at all.
How to Select a Feminized Plant That Won’t Hermie?
It works like this. You take a bunch of regular seeds, grow plants from them, put them into the flowering mode, and when they reveal their sex, discard all males. As for the remaining females, you wait till they begin to flower in earnest and then start to stress them. You can doi it by constantly changing the light cycle: when today it’s 12/12, tomorrow — 18/6, then — 14/10, etc. All weaker genetics—when ‘punished’ this way—will turn hermies at some point. And the ones that stay female despite all the stress are definitely keepers. Meaning they are your best choice for feminized seeds production.
Do Feminized Seeds Produce Different Phenotypes?
Making seeds that always turn female and making seeds that grow into very uniform-looking plants are two completely different things. So, with feminized seeds, a breeder never guarantees that you will get only one pheno. The phenotipic variance can be as huge as with regular seeds. And if you want feminised seeds that don’t have different phenotypes, make sure that the breeder or reviewers describe the strain as stable.
So, we did our best to define feminized seeds’ meaning. Now let’s take a few moments to dispel some misconceptions that people have about this type of marijuana seeds.
Feminized vs Autoflowering
Some people, when they choose a strain, wonder what they should rather buy: feminized seeds or autoflowering. As if these were opposing terms. In fact, they are not. The confusion is understandable: seed shops offer seeds in two large categories:
- feminized autoflowering seeds -> usually shortened to just ‘autoflowering seeds’,
- feminized photoperiod seeds -> usually shortened to just ‘feminized seeds’.
The fact that the words not marked in bold are too often omitted has created this confusion. In fact, there are also regular autoflowering seeds and regular photoperiod seeds, but neither category is very popular. Most newbies don’t even see them when they shop for seeds. All they see are the words ‘feminized’ and ‘autoflowering’, and so they feel like they should choose either one or the other. The good thing is you can have both. Autoflowering feminized seeds produce only girls, and they all start to flower automatically.
This confusion aside, we’ve written a separate post discussing pros and cons of autoflowering vs non autoflowering seeds.
How to Tell Feminized from Non Feminized Seeds
Another misconception is that feminized seeds somehow look different than other types of seeds. Not by a long shot. A seed is a seed. It can be small or large, or it can look mature or immature, but, other than that, you can’t tell anything about the seed’s genetics by just looking at it.
It can be medical cannabis or hemp, sativa or indica, an auto strain or a photoperiod one, it can be a high THC or low THC variety, or CBD rich etc. and all of them will look just the same.
And if you insist on knowing what type of seeds you have—feminized or not—the only sure way is to wait till they flower.
Do Feminised Plants Produce Seeds?
If feminized seeds catch some pollen, they do produce seeds. After all, they are feminized, not castrated. The reason why people have seed-free harvest of buds from feminised seeds is because they don’t have any males in their grow room and no male pollen. But if you get some pollen inside your grow space (from outside or from hermies), your plants will get pollinated, no matter feminized or not. So, if you bought only fems and still your feminised plant has seeds, look for the source of pollen.
How to Grow Feminized Seeds
There is a whole group of questions from novice growers regarding germination and planting of feminised seeds, their grow time and flower time, light cycle, phenotypes and what not.
We’ve already said that feminized seeds look exactly like non-feminized. Well, they also grow the same and should get the same treatment as regular seeds. The only real difference is that you won’t have to cull the males when the plants in your garden show sex.
Maybe there is one more difference. If the breeder hasn’t done his job properly and his fem seeds genetics are unstable, the seeds will be more prone to become hermaphrodites. In this case, take extra care not to stress your feminized plants at any point of their life cycle. Other than that, take care of them just the normal way and you’ll be alright.
Do Feminized Plants Produce Seeds: Question Answered
Any cannabis user who has enjoyed and savored a cannabis joint owed this feeling to the fruits of the cannabis, more specifically to the female species. The reason behind is that only the female cannabis produces the cannabinoid-rich flowers that are responsible for the flavors and effects that users look for. A lot of cannabis growers are using feminized seeds but some people are curious, do feminized plants produce seeds?
These feminized seeds are cannabis seeds that only carry female genetics and can be relied on to produce only female plants. Cannabis growers apply creative techniques to seed feminization to ensure female genetics in seeds partnered with a nearly 100% success rate. Here we give you the overall information you might need to know about feminized cannabis plants.
What are Feminized Cannabis Seeds?
Feminized cannabis seeds are produced in a way to ensure that all the resulting plants will be female. The difference they have with regular cannabis seeds is that the regular seeds will produce half male and half female plants.
Although having a male plant can be considered an asset to any breeding program, the downside is having to watch over and throw away half the plants. This can be a waste of time and space for growers who needs to have a continuous supply of cannabis bud.
Do Feminized Plants Produce Seeds?
If you’re a novice in the cannabis industry and you’re wondering do feminized plants produce seeds, the answer to curiosity is that yes. It will produce seeds and the seeds will become feminized as well.
A lot of cannabis growers invest in growing feminized plants because of the sure return of the feminized seeds. These seeds are going to give female plants that in turn will produce buds and the cycle will repeat itself automatically.
How to Feminize Cannabis Seeds
There are two methods to feminize seeds: naturally or by applying a chemical substance that forces a female plant to pollinate. In essence, a severely distressed female cannabis plant will naturally become a hermaphrodite and it will produce pollen sacs in order to self-pollinate.
This is actually a survival mechanism built into all female cannabis plants but this can only be triggered when the future of the plant’s lineage is compromised. Having a hermaphrodite can cause a disastrous breeding situation as it can pollinate female plants that are meant to be harvested which will, in turn, cause the buds to stop developing and to produce seeds.
Using a colloidal silver to a female plant is the preferred method of feminizing cannabis plants. This causes the plant to develop pollen sacs without compromising the lineages genes and here is how you can it in your own home:
- Choose two female plants that you will use. You need to make sure that each plant has strong genes. One of the plants will be chemically treated to grow male sex organs while the other will be pollinated.
- Purchase a colloidal silver solution that has a minimum of 30 parts per million (PPM) of silver. You can buy the colloidal silver solution in any store that sells dietary supplements.
- Spray the colloidal silver solution. You can directly apply the colloidal silver solution on the plant’s bud sites until they are drenched, you should do this each day of the first 3-4 weeks of the plant’s flowering stage.
You should stop spraying once you see the pollen sacs have appeared and beginning to open. Never smoke the buds that form on this plant because they may have been coated with colloidal silver.
- Collect the pollen. When you notice that the pollen sacs are swollen and begin to split open, this is a clear indication that the pollen sacs are ready to be harvested. You can harvest it by simply removing the pollen sacs from the plant and let them air dry for about a week and once it dries out, shake the sacs in a bag to gather the feminized pollen.
- Pollinate the second plant by using the pollen you have gathered. Take note that the female plant should have been in 2-3 weeks into its flowering stage for it to be pollinated.
- You can wait for about 6 weeks to harvest the seeds. Harvesting should be done once you notice that the calyxes on the pollinated plant are swollen and showing seeds.
Reason for Trying Feminized Seeds in Your Garden
Better Cannabis Genetics
A lot of cannabis strains that came from feminized cannabis seeds have had their genetics carefully controlled by a breeder. This is to ensure that it brings out defining characteristics of each strain. An advantage of this is that it gives consumers more options in terms of flavors, aromas, and cannabinoids.
These feminized plants are believed to be more productive, aromatic, powerful and attractive. The feminized seeds are also made to ensure that the plant being grown are working well in the conditions that a grower is growing on.
These feminized plants give a guarantee that no plant will be male or a hermaphrodite. When a female cannabis plant undergoes extreme stress, it can affect the results but using feminized seeds is a good way to increase yields, save work, and get higher value from the seeds.
Clone and Breed with More Control
When a breeder uses feminized plants for cloning, it gives them a greater likelihood that the plant is going to be a female plant. A noticeable advantage of using feminized seeds is the ability to better control the breeding of the plant.
It offers more control over the whole process and it seeks to standardize the cannabis industry. Also, it has helped by making the process of growing more reliable and for many reasons, it has become the standard in the cannabis industry.
Allows growers to work less with the Plants
If properly grown, a feminized cannabis plant can give a 100% guarantee that each plant grown from the seed will produce large amounts of bud. This will mean that a garden will yield more if they operate at or below plant count restriction.
