How to Feminize Seeds
The cannabis industry has evolved more in the last 15 years than it has in the last century. Society has also evolved, allowing cannabis and the idea of weed to slowly make its way into pop culture, with more and more strains available as well as accessories for smoking or consuming cannabis. Nowadays, pretty much anyone can grow cannabis in their own house with all of the necessary equipment to make their own strains. Years ago only a select few had access to such equipment. Today we’re going to show you how to feminize seeds. You won’t need many items to do so, and the ones you do need are easy enough to get.
Like most living creatures, cannabis plants need a male and a female specimen to reproduce; the male pollinates the female plant which causes seeds to grow. The resulting seeds have genes from both the mother and father plants, so it has a 50% possibility of being female or male. This is why you need to find a way to get your seeds by using just female plants, completely getting rid of male genes, which only leaves the possibility for female seeds.
How to Feminize Seeds | Tutorial
Many growers know that if you stress out cannabis plants, they can easily become hermaphoridtes (a plant with both male and female sex organs) which end up creating male flowers that create pollen which then “impregnates” the plant and others around it. The issue with stress-caused hermaphrodite plants is that most of the resulting seeds tend to be hermaphrodites too, so it’s not the best method to use and it also stresses your plants out quite a lot.
In order to turn a female plant male without stressing it out, all you need is some Silver Thiosulfate, also known as STS. If you apply STS to female plants it will modify their ethylene levels, which is the hormone in charge of determining the sex of certain plants. This causes female plants to change sex and turn into males without the disadvantage of male genes.
Making your own STS only takes about 15 to 20 minutes and you’ll need two ingredients: Sodium Thiosulphate and Silver Nitrate, both of which can easily be found in any pharmacy and on our webstore. Sodium Thiosulfate is a neutral chemical salt that’s used to reduce side-effects in some cancer treatments and can easily be bought without a prescription.
You can acquire silver nitrate on our webstore, although some people prefer to extract it from other products that contain it, such as Argenpal, a product used to get rid of warts – each one of these little contains a very small amount of Silver Nitrate, so it’s probably better just to buy it directly without the need to spend more money or spend forever trying to extract the Silver Nitrate from the product itself. We stock Panreac Silver Nitrate, which may be a bit more expensive but you’re guaranteed the best quality, and it saves quite a lot of time.
How to Feminize Seeds | Making STS
You’ll need protective material such as gloves, safety glasses and a face mask; STS can be quite toxic when inhaled and it can leave large burns on the skin. Make sure you don’t use any metallic objects when making STS – everything should be plastic, as metal can alter the composition and reduce efficiency.
Do not use metal instruments or tools in this process. The first thing you’ll need to do is grab a plastic cup and pour in 20ml of distilled water. Next, depending on your chosen method, get either 7 Argenpal sticks or 0.35g silver nitrate. If working with Argenplal, dilute the tips delicately in the water (the tip is where the silver nitrate is). Grab another plastic cup and add 30ml distilled water and 1.3g of sodium thiosulfate, mixing it slowly until it’s fully dissolved. Then, mix the contents of both glasses and mix slowly again – make sure to use a plastic spoon, no metal.
The result is 50ml of pure Silver Thiosulfate, much too potent to use on your plants, so you’ll need to water it down a bit. Add your Silver Thiosulfate to 400ml of distilled water, so you’ll have around 450ml of STS. Make sure to shake quite a lot until it’s completely mixed. It’s still much too concentrated to apply straight onto your plants; take 100ml of the mixture you just made and add it to 400ml mor of distilled water. You now have 500ml of a usable STS mixture that’s ready to be used on your plants.
For maximum efficiency you’ll need to use it the same day you make it. If stored in a dark, cool space it can last up to 15 days but each day it’ll be a bit less potent. If you have it for over a week and haven’t used it we recommend making another batch if you want the best possible results.
How to Feminize Seeds | How to use STS
STS is used by spraying it on your plants leaves, making sure that it’s entirely covered and dripping. We recommend taking the plant away from your growing area before beginning the process, or the mixture might end up getting on your other plants too. You’ll need to begin applying it 4 or 5 days after flipping the lights, right before your lights go off. This allows you to spray the plant without worrying about the light burning your plants. After 10 days, you need to respray your plants, using the same process, covering the plant in the mixture and letting it soak in in the dark.
The sprayed plant will begin growing male flowers with pollen with can then be used to pollinate whichever plant you want, causing seeds to appear that have absolutely no male genes in them. You can use the pollinated plant in order to make extracts from its resin; the amount of seeds it’ll produce will render it pretty much useless in as far as smokeable flowers. The plant that you’ve applied the STS to will need to be thrown away, as it’s much too toxic to do anything with and if you consume any of it, even its resin, you could run in to some health issues.
When should you polinate your plants?
In order to efficiently pollinate select plants, we recommend having two completely separate grow rooms or areas to work in. One should be for the plants that you’re planning on switching to male in order to obtain female polen; the other should be specifically for the plants that you plan on pollinating once you’ve reverted the other ones.
When using the pollen that you’ve collected from your reverted plants, you need to make sure that the plant that you plan on using it on is fully ready for it; this can depend on the strain you’re growing. The right time to begin applying feminized pollen is actually right when your plants begin to flow real flowers.
You generally want to use the pollen as fresh as possible on a plant that is fully ready to take it on, or else it simply might not work – it’s kind of like people, in that sense. Certain things need to be just right. To harvest large amounts of high quality seeds, you’re probably better off doing a few tests in order to find out when the right moment is. You can do this by testing it out on the same strain before going big.
How to Feminize Seeds | Make your own strains
When making your own seeds you can combine your favorite strains, resulting in a plant that you’ve created yourself that is 100% feminized. When you combine two strains, you’ll get various phenotypes with varying qualities and structures. It’s important that you use regular seeds to do this, as feminized ones are much too weak and might have issues such as stress and end up becoming hermaphrodites.
In order to stabilize the genes in your resulting plants, you’ll need to select the phenotypes you like the most, meaning that you’ll need to grow quite a lot of the seeds that you get from your feminized plant. Then, take a clone from each plant and set them to flower in order to study their characteristics. Once you’re done, you’ll need to pick two mother plants, revert them and cross them with each other to get a more balanced version. This process is repeated as many times as necessary in order to create a balanced strain that has the characteristics you’re looking for.
Feminizing cannabis seeds is quite the process. You need to be able to keep perfect track and control of the timing when it comes to flowering and pollen yield if you want the best possible results. Take your time, do a few controlled tests and then you can start making large amounts of your own seeds.
How To Feminize Cannabis Seeds
If you’re a home grower who grows your cannabis from seed, you need those to be female seeds. In this article, we’ll explain why and also how to feminize cannabis seeds.
Table of contents
What Are Feminized Cannabis Seeds?
Cannabis plants are dioecious beasts, meaning they can be male or female. Although they look the same in the early part of their life cycle, there are marked differences between the two. Male cannabis plants produce male seeds and pollen sacs and have much lower potency than females. For that reason, most people involved in cannabis cultivation want to grow female cannabis plants. Females produce the much sought-after buds that cannabis is harvested for. They’re high in cannabinoids and terpenes and have all the trichomes and other components you need for medical or recreational cannabis use.
Why Make Feminized Cannabis Seeds?
As opposed to regular cannabis seeds, which produce female plants approximately half of the time, feminized seeds only produce females. That means every plant grown from feminized cannabis seeds will be a female, bud-bearing beauty.
Growing cannabis plants from feminized marijuana seeds takes the guesswork out of the gender game and guarantees your plants will be female.
Nowadays, almost all strains of cannabis are available in feminized seed form. This is because seed banks understand that most people buying seeds are more interested in producing cannabis flower. As such, the option to do so is available – although, if you’re a breeder and want to create a breeding programme, these seed banks also sell regular seeds of many popular strains.
How Do You Make Feminized Cannabis Seeds?
The general idea of the feminization process involves forcing female plants to produce pollen. That pollen is used to pollinate other female cannabis plants, resulting in feminized seeds.
There are two main ways to achieve this:
1. Chemically-induced pollen feminization
Of these two options, it’s far better to go chemically-induced. This method is used by professionals and has a significantly higher success rate. It also has a much lower frustration rate than the latter method. Rodelization creates feminized seeds through stress and, as such, can be a risky endeavour that increases the likelihood of hermaphrodite plants – and you don’t want hermie plants.
Marijuana plant and Cannabis seeds in a plate
So how do you feminize cannabis seeds with chemicals? There are several techniques and chemicals that you can use. The main ones are Colloidal silver, silver nitrate, silver thiosulphate, benzothiadiazole, and gibberellic acid. Of these options, colloidal silver is the easiest to get a hold of, but you can also make it yourself without too much difficulty.
Colloidal silver is a solution comprising tiny – microscopic particles of silver suspended in distilled water. It’s sometimes used as a dietary supplement, meaning it’s reasonably easy to get a hold of. You can buy it on Amazon or from health shops. Disclaimer: Never ingest colloidal silver as a dietary supplement without speaking to your doctor beforehand.
Colloidal silver has other uses in horticulture, including as a means of fungal control. In creating feminized cannabis seeds, colloidal silver works by inhibiting the production of ethylene, a naturally occurring hydrocarbon gas. Ethylene is a hormone needed to produce female flowers, so we use colloidal silver to prevent ethylene from effectively making plants female. The result is that the male hormones dominate, producing male flowers. Afterwards, you collect the pollen from the plant and use it for pollinating other plants, producing feminized seeds. Colloidal silver guarantees you consistently get feminized seeds.
The Colloidal Silver Method: Step by Step
- Begin by acquiring the right strength of colloidal silver, preferably 30ppm (ppm meaning parts per million). It’s available in other concentrations, and 30ppm seems to be the best for the job. Lower than 15ppm will result in male sacs with next to no viable pollen, so go with a higher concentration.
- Select a plant that has the traits you wish to preserve. Put it into a small pot away from your grow room and give it a day or two to adapt, then put it on a 12/12 light cycle as soon as possible. If using a clone, you’re good, but if you’re growing a plant from seed, wait until the plant has sexed before treating it with colloidal silver. You need to make sure it’s female!
- Once it begins the flowering stage, spray the plant, or plants, three times a day with colloidal silver, giving them a good soaking. Repeat this process over two weeks, and then leave them to grow as usual.
- When sexing begins, your plant will develop sex organs – look for male pollen sacs on the bud sites rather than the calyxes and pistils seen in female plants. Look for little green balls appearing first at the top and then lower down the plant. Viable pollen appears within three to four weeks once the plant has been sexed. Collect the pollen and use it to pollinate other female plants. These plants will then yield feminized seeds.
- Keep your treated plant isolated well away from females. If a pollen sac should burst, it will release millions of spores, and you don’t want them near your girls.
As soon as you’ve collected the pollen, discard the plants. Do not smoke them, and do not be tempted to try and rinse the colloidal silver off. Silver is a toxic metal, so never smoke the plant. Colloidal silver is absorbed into the plant’s foliage, and that plant is no longer fit for consumption. Toss it in the trash immediately.

How To Make Feminized Seeds At Home: A Complete Guide
Learning how to make feminized seeds deserves a spot on any sustainability-focused cultivator’s to-do list.
Fem seeds let you bypass the potential pollination struggle and cultivate only seedless buds every time. This variety (and its accessibility) is a gift that keeps giving, but some growers are after a higher level of self-reliance.
Feminizing marijuana might take some trial and error, but anybody can master it with enough dedication. Once you do, fem seeds of any strain you wish become available at any time.
Join us and discover how to feminize seeds at home.
How are feminized seeds made?
Before discussing how to make feminized seeds, here’s a short biology lesson to make sure everybody’s on the same page.
All marijuana seeds are ‘regular’ at first, developing into male and female plants at an approximately equal rate. Females produce buds, which serve as a holding space for new seeds upon pollination. Male crops create the pollen necessary for this process.
Males fertilize females in natural environments, causing more seeds to develop. That’s excellent for the persistence of the species, but it can be a pain for smoking purposes.
To make feminized seeds, you need to cross-fertilize one female plant with another. That way, no male chromosomes enter the picture, letting all offspring remain bud-bearing females.
Since female marijuana doesn’t produce pollen on its own, we introduce additional elements that enable fertilization. Here’s where another concept emerges—ethylene.
Ethylene is a cannabis hormone responsible for aging. Among other functions, it induces flowering, regulating how the plant expresses its sex. Females with low ethylene levels grow male flowers, making feminized cannabis seeds possible.
This process sounds like a whole lot of chemistry, manipulation, and trouble, and you might be reluctant to give it a shot. Let’s explore the reasons you’d want to pursue it.
Why should you make feminized cannabis seeds?
Fem seed varieties are all the rage on the marijuana market. Why bother with feminization when this variant is available for purchase? We’ll discuss how to make your own feminized seeds, but first, let’s see why you should do it.
Availability stands as the primary reason. While most cultivars come in feminized versions, not all do. You can only get regular marijuana seeds of certain strains, making sticky bud cultivation a hassle.
After feminizing marijuana, it produces hundreds (sometimes even thousands) of seeds.
What’s more, you could practice strain crossing without having to deal with new hybrid males. Knowing how to make feminized marijuana seeds lets you taste the results of your original idea in their full glory.
Growers on a budget reap extra benefits. Feminized seeds are usually more expensive than their regular counterparts, making this process an investment.
Of course, you could produce more regular seeds, but that means that about 50% of each garden goes to waste every time. Even worse—males could pollinate females, leaving you with more seeds but no buds to smoke.
Female seeds are a different story. They develop into fem crops 99% of the time, eliminating this headache-including concern. Making feminized seeds now brings the following benefits to every future cultivation journey:
- No risk of pollination in your garden.
- Seedless colas with a high smoke value.
- Higher cannabinoid and terpene contents.
How to make feminized seeds at home?
As we mentioned earlier, studying how to feminize marijuana seeds incorporates various interchangeable methods.
Below, we share three ways to cause this structural shift in a female crop. Choose according to your skill level, desire for accuracy, and comfort with using chemical agents.
How to make feminized seeds using the rodelization method?
How to produce feminized seeds without using chemicals? Roderalization is an all-natural method of forcing female crops to develop male pollen sacs.
Staying seedless is an unnatural state for female cannabis plants. Like most things in nature, its main goal is to produce offspring and help the species survive. Evolution found a handy way to make this happen.
As the end of its life cycle approaches, a marijuana plant in nature develops male organs, self-pollinating to produce more seeds. Think of it as a last-ditch effort to propagate its genome.
Of course, any grower for smoking purposes would collect the colas before this happens. If you’re after new seeds, though, nature can do half the work for you.
Here’s how to make feminized seeds with rodelization:
- Care for your plant as normal until the end of flowering.
- When the harvest period arrives, don’t touch your plant.
- Let the crops sit under the same flowering conditions for two to three weeks.
- You’ll notice stamens and anthers (pollen-producing organs).
Feminizing marijuana this way is easy and cheap, requiring only time and patience. It’s ideal for first-time seed producers who aren’t comfortable with using chemicals.
Note that this technique can be a hit-or-miss, though. Even if there’s pollen, there’ll be much less to go around than with other methods.
Note: Although rodelization doesn’t produce hermaphrodites (crops with male and female chromosomes), their offspring have hermie tendencies.
How to make feminized seeds with colloidal silver?
While rodelization is great for first-timers, many growers seek efficiency and higher success rates. For that reason, they use colloidal silver to make feminized seeds.
Colloidal silver is a distilled solution of water and microscopic silver particles that inhibit ethylene production. You can get it commercially or make your own.
If you purchase from a store, get a solution with at least 15ppm silver. A product around 30ppm is ideal.
In the spirit of keeping everything sustainable and self-sufficient, we’ll provide an alternative to shopping. Here’s how to make colloidal silver at home:
- Gather supplies. You need a 9-volt adapter, two electrical wires, two clips, distilled water, two silver pieces, and a ppm meter.
- Strip the wires. This method of making a solution for feminizing marijuana requires unbridled electricity.
- Connect a clip to the end of each wire.
- Fix the wires to each end of the adapter.
- Place a piece of silver in each clip jaw.
- Fill a jar 3/4 full of distilled water and suspend clips on opposing sides of the container.
- Turn on the adapter and let it work.
The solution for making feminized seeds turns pale gold after around 20 minutes. The meter should read at least 15ppm silver, too. After that, all you need to do is let the liquid sit and cool.
Once you have your product, here’s how to make feminized seeds with colloidal silver:
- Pick a female crop that’s early into flowering. The earlier you start, the better the outcome.
- Soak the plants generously using a spray bottle. Focus the silver showers on future bud sites.
- Keep spraying daily for two weeks. Try doing it at the same time each day.
- Leave the marijuana plants to grow as normal.
You should start seeing pollen sacs within a month, but it’s a good idea to move these crops from any smoking-purpose plants right away. Otherwise, you’re running the risk of a random pollen burst fertilizing an entire garden.
Making feminized seeds with colloidal silver is straightforward and almost 100% guaranteed to work. The crop you used is a write-off, though. Colloidal silver travels through the plant, causing flower toxicity.
How to make feminized seeds with STS?
Making feminized seeds with silver thiosulfate (STS) is a recent technique, but its efficiency is helping it gain traction. It’s the only option that brings the 99% feminized figure of other techniques to a certain 100%.
STS is a solution of distilled water, sodium thiosulphate, and silver nitrate. It halts ethylene production, forcing male flowers to blossom. As with colloidal silver, the plants are no longer viable for consumption once you spray them.
Much like silver, the elements for STS are accessible in most pharmacies and online shops. You can make this liquid yourself or get a bottle on Amazon and go to town with it.
If you decide on the first option, you need to prepare two solutions and only mix them when it’s time for feminizing marijuana. Always use protective equipment and choose glass or plastic containers to avoid contamination.
Here’s the recipe:
- Pour half a liter of distilled water into a measuring cup. Measure 0.5 g of silver nitrate before adding it.
- Stir until the crystals dissolve. Pour solution A into a brown glass bottle.
- Repeat step number one with 2.5 g of sodium thiosulfate.
- Stir and pour into another bottle. You now have solution B.
- Combine 50 ml of solution B, 50 ml of solution A, and 800 ml of distilled water in a spray bottle.
- Add ten drops of washing detergent and lightly shake the mix.
The liquid should stick to leaves, not immediately slide down. If it does, you need more detergent in the blend.
Once the chemistry exercise is all done, here’s how to make feminized seeds with STS:
- Start spraying five days before the flowering stage. Focus on the leaf areas and be generous with the soaking.
- Continue spraying once every five days, covering the roots with paper to avoid damage.
- Continue for four weeks. Spray at night to help the crops soak in the solution.
- Leave the plant to develop as normal after the four-week mark.
You should see pollen after another month. If you notice any yellowing or burnt tips, add more water to your STS liquid.
This technique for making feminized seeds requires more caution, but it’s as effective as it gets. Once you master the application, STS massively reduces trial-and-error, making it even easier to move on to the next stage.
How to handle pollen for making feminized seeds?
The main section of making feminized seeds is over. Your female crops are now forming pollen sacs, and you’re soon to collect the precious substance and finish the cycle.
Let’s talk about the steps that follow feminization.
How to collect pollen
Collecting pollen is the next level of teaching yourself how to make feminized cannabis seeds. This one is all about timing.
As a rule of thumb, wait until the sacs swell but act ASAP once they do. Otherwise, they can burst and pollinate nearby female plants, ridding you of your precious source.
When the time is right, cap the top of your plant with a plastic bag. Fix the cover around the crop and remove the male flowers one by one. Be careful when grabbing them to avoid pollen explosions.
Leave the sacs to dry for a few days and filter them using a micron sheet. Place a sheet of parchment beneath and shake the pods, letting the golden powder fall and collect on the flat paper surface.
You can use this pollen to make feminized seeds right away or store it for future use.
How to store pollen
If you plan on making feminized seeds later, the pollen remains fresh for a week in the fridge and up to a year in the freezer. The key idea here is to avoid moisture.
Storage with cooking flour is the way to go for avoiding humidity issues. Combine the two powders, sticking to a 3:1 flour to pollen ratio. Wrap some paper around the mixture and place it inside an airtight, opaque container.
Tip: Reduce the amount of oxygen in the jar to further prevent degradation. You could also add paper, cotton, or rice to the container.
Wrap reusable bags around your container. Leave it in the cold spot of choice, staying vigilant about temperature fluctuations.
How to pollinate the plants
How to make female seeds? Pollinate female plants with female pollen. The process can begin as early as two weeks into flowering. The method depends on the number of seeds you’re looking to produce.
If you’re going for smaller-scale production, use a soft-bristled paintbrush to dust the pollen onto buds and branches. The spores stick to the trichomes, making fertilization easy to localize.
If you aim to make feminized seeds from an entire crop, there’s a quicker way to do it. Place the pollen in a bag and cover the crop with it, shaking to help it spread. Let the bag sit there for another day.
You’ll have to wait for another four to six weeks before the plant produces seeds. Keep providing optimal conditions during that time.
Grow female marijuana from your own stash
