How to Make Feminized Seeds Easily at Home
If you’re not a total beginner as a grower, you probably know that male cannabis plants pollinate female plants. You may also know that only female plants produce the flowers that cannabis fans know and love.
The problem with male plants is that if they pollinate your girls:
- The girls will produce seeds
- Their buds will have less resin & THC
- Your total bud yield will be lower
Growers normally buy feminized seeds from breeders and seed banks because they can count on almost all of those seeds becoming female plants with high THC and all the other goodies cannabis has to offer.
Here you will learn to feminize seeds yourself.
What is a Feminized Seed?
A feminized cannabis seed is what you get when you breed two female plants instead of a male and a female. When you plant feminized seeds, they germinate and grow into females.
The way to feminize seeds is to force females to produce pollen sacs. You can use that pollen to fertilize other females.
How do you trick them into producing male buds? Induce environmental stress or change their hormones chemically.
Choice #1 – which is called Rhodelization – is not a favorite method of breeders. It’s more complicated than changing hormones.
The trick to rhodelization is to fool the girls into “thinking” that they’re dying. A female anticipating death wants to optimize the continuation of the species. When they think they’re doomed, they will produce female seeds almost exclusively. This is because a small number of male plants can fertilize an entire room full of girls, so very few of them are needed. Cannabis pollen outdoors travels far and wide. The girls are more essential.
How to Make Feminized Cannabis Seeds by Changing the Hormone Balance Chemically
This is the most common method top breeders use to feminize seeds.
To do this, you can use one of four substances:
- Colloidal silver (CS)
- Silver thiosulfate (ST)
- gibberellic acid (GA3)
You can find colloidal silver at bricks and mortar natural foods stores or through online supplement stores. If you want to make your own, there are plenty of guides online that show you how to do that.
Step 1: Grow 1 or More Female Plants
Let these ladies grow through the vegetative stage.
Step 2: Spray the Bud Sites Daily
When the buds start forming, put colloidal silver in a spray bottle and drench the bud sites once per day. The buds will develop into male-like buds that have the power to pollinate. The process will take three or four weeks. Don’t stop spraying them until the pollen-filled buds start opening and the leaf that protects the pollen begins to crack.
Warning: If any female buds form, don’t smoke them. They could be dangerous because of the chemicals.
Step 3: Harvest & Dry the Pollen Sacs
Pluck the pollen sacks. Place them somewhere that allows them to dry. The drying process should take about a week.
Step 4: Put Your Sacs in a Bag & Shake ‘em Up
You can use a can for this, too. The sacs will release pollen when you shake them. Keep your container closed while doing this so that no pollen escapes.
Store your pollen in a ziplock bag or something air tight.
Step 5: Fertilize Some Lady Plants
The best time to pollinate your plants is when they are about two or three weeks into the flowering stage. If you wait too long, they’ll produce less seeds.
Do this step in a closed room. It’s a delicate process. There are lots of tutorials online about how to pollinate cannabis. Find a good one and follow the steps.
Step 6: Harvest Your Feminized Seeds
You can tell the seeds are ready when some of them start dropping from the buds. They should be brown and not green. You may need to give the plant some nutrients or whatever it takes to keep her alive so that she can get to the seed dropping phase.
Harvest the seeds with your fingers.
Step 7: Store Your Seeds or Plant Them
Keep your seeds in a cool and dry place. Mark them with a harvest date so you know how old they are. If you store them properly, they’ll keep for a few years. You can plant them any time after harvest.
How to Feminize Seeds
It’s important to learn how to feminize seeds so you can save time on your grow. When the traditional fertilization methods are used to grow your marijuana plants, you have less control over the gender of future marijuana plants.
That is why many marijuana growers take extra steps so you receive female marijuana plants at the time of harvesting. To do it yourself, feminize seeds prior to your harvest.
What are Feminized Cannabis Seeds?
Feminized cannabis seeds produce only cannabinoid- and trichome-rich flower buds on female cannabis plants. Cannabinoids and terpenes are responsible for the potency, aroma, and flavor of cannabis.
A crop that uses high-quality feminized seeds will produce a female-only crop without the presence of male plants, which can pollinate your crop and potentially reduce your yield.
Another type of seed, a regular seed, is a result of natural pollination and breeding male and female seeds together. Cannabis growers working with regular seeds have a 50% chance of either yielding a female or male marijuana plant. Growing from regular seeds isn’t the best option if you’re looking to strictly grow cannabis buds. While male plants serve their specific purpose to pollinate females, they don’t produce the trichome covered flowers that female plants do.
How Are Feminized Seeds Made?
Feminized cannabis seeds serve a major purpose for commercial and home growers. Feminized seeds can be made by inducing a regular female cannabis plant to grow male sex organs that contain pollen. The hermaphroditic pollen will contain only the female X chromosome and no male Y chromosomes.
When used to pollinate a female cannabis plant, the seeds produced between the two plants will inherit two X chromosomes meaning that all subsequent seeds will be feminized.
The Benefits of Growing Feminized Seeds
Growing feminized cannabis seeds has many benefits over regular seeds. For one, growers don’t have to hedge their bets hoping that the regular seeds will produce female plants. Instead of planting more regular strains than needed to get lucky and get enough females for your specific purpose, you can stick with a sure bet using feminized strains. Using feminized seeds can speed up the growing process by eliminating the need to watch out for male plants, saving you time and space.
Male plants run the risk of pollinating female plants causing them to develop hermaphroditic structures and, ultimately, lower your plants’ yield compared to a grow without male plants. Weeding out the male plants, however, takes time and energy. Male plants display their sexual organs when the photoperiod changes naturally or when indoor lighting environments change.
Growers that don’t want to spend the time monitoring the plant every day can use feminized seeds to ensure that their garden will grow flower buds. Otherwise, growers will have to keep their eyes peeled for male plants and remove them from the grow immediately.
Male vs Female Marijuana Plants
Generally speaking, there is no way that you can determine the difference between male and female marijuana seeds in the initial stages of planting. In addition, you are also not able to change the gender of your marijuana deeds. The concept of having feminized marijuana seeds is to maximize the female seeds that will be part of your marijuana crop. Why would you want female marijuana plants? Well, these are known to have a higher level of THC content. Male plants have reduced THC content and for that reason, female plants take precedence over male plants. With cannabis seed feminization, there are several pollination techniques that the marijuana grower can use for a favorable outcome.
Buying the Right Cannabis Seeds
Female marijuana seeds are sold by various companies. So, you don’t have to wait to get your own. You can use the ones available to you and by doing so, you will be sure that your outcome is a female marijuana plant with more THC content. Be careful when buying marijuana seeds from companies online. Make sure this is a reputable company known for selling and delivering the right female marijuana seeds.

Some “feminized” seeds may produce hermaphrodite plants if the seeds are of low quality. High-quality feminized cannabis seeds from reputable seed banks have been bred to not display hermaphroditic characteristics under optimal growing conditions. If you’re looking for a sure thing, carefully consider your cannabis seed source.
Alternative Methods to Feminizing Weed Plants
If you are going to do the feminization of marijuana seeds yourself, then there are methods that you can use namely:
- Colloidal Silver
- Silver Thiosulfate Solution
Each of these methods should be successful, if used in the right way to produce female marijuana plants. Let’s quickly look at each method briefly.
Pollinating Cannabis Plants
One of the simplest ways to produce feminized cannabis seed is to pollinate your plants yourself. Some cannabis strains can produce male flowers when the colas have reached late ripeness. Side note: Ed Rosenthal, master grower and proud member of the CTU faculty, prefers to harvest plants around this time. Harvest the pollen by using a clean and small painting brush to transfer the pollen into a metal or glass container or in small amounts directly on the flowers.
Some outdoor-friendly cannabis strains may become stressed when grown in indoor environments, which can increase the chance of producing hermaphrodite flowers. Indoor growing environments can stress plants with fluctuating light cycles and heat. Stress training techniques are difficult to pull off, even for experienced cannabis growers. If you do happen to spot a hermaphrodite with pollen, collect the pollen and save it for later use when you feel comfortable using it.
Using Chemicals To Feminize Seeds
Large-scale and home growers have harnessed the power of certain chemicals that can induce male flowers in female marijuana plants. These chemicals are used to hinder ethylene production. Ethylene is a plant hormone that helps cannabis plants ripen and produce female flowers. When ethylene production is stalled, female flowers aren’t produced. Keep in mind, these chemicals must be directly applied to each branch that you want male flowers to grow.
The Silver Thiosulfate Method
The Silver Thiosulfate Solution, also known as STS, is one of the most common methods of generating female marijuana seeds. It is very effective in allowing female marijuana seeds to be available to marijuana growers. Using this method will feminize the seeds in the best way possible, making more available on the market for growers. The solution is made of a combined silver nitrate and sodium thiosulfate. The solution result is a hormonal response to stress found in the marijuana plant. Because of this, gender change is triggered.
You can do all of this yourself, but the marijuana plants have to be wisely chosen. You should only take female plants from a single cannabis strain that is almost mature. Then you would separate the plant from the bunch and spray the plant with STS. Allow it to dry and then replace it, making sure it sits alongside the other plants in the bunch.

The truth is, having one season’s worth of a great harvest is a good thing – but you could make it great by setting your sights on the future.
You have so far achieved some very difficult stuff during your grow season. Maybe you had to overcome unforeseen obstacles. Do you want to make things easier next time around?
If your plants are currently maturing, start taking a closer look at them. Are there growths forming at the spot where stalk and leaf connect? Are some of your plants growing tall and skinny while others are remaining bushy and short?
These changes come from your plants reaching their sexually mature stage. As soon as this starts happening, you should be able to accurately decide which plants you will want to reproduce so you have a stash of pot for the entire year.

In this article, we will cover the basics of looking to future generations of growing seasons. The secret of success is your plants’ seeds, as well as the sexes of those seeds.
How to sex plants
The first step in making these crucial decisions is to determine which plants are male and which are female. You should start being able to do this once the season starts to change.
As soon as the length of daylight falls below eighteen hours per day, you will begin to see responses in the male plants. They will start to grow bud-like growths, which are actually greenish-white flowers in the shape of an egg. You won’t be able to mistake its gender once you shake these flowers since they will give off a cloud of pollen.
About two weeks later you will start to see distinct changes in the females as well. They will start to grow buds, which begin as a little cactus-like white growth at the ends of branches.
These buds will grow and grow until about a month has passed, at which point they will be significantly larger, sticky with resin, and odorous. Depending on the strain you are growing, this odor could smell similar to a skunk, or it could have a sweet, pleasant smell.
- Time your harvest for Perfect Taste
- Get THC levels for a Perfect High
- Don’t waste any Precious Bud
Surprisingly, you can get a pretty good idea of which plants are male before they start reacting to the changes in daylight. In general, the male plants will be the tallest of your crop.
This is a simple evolutionary trait that was naturally selected over generations – by being taller and maturing faster, males are more likely to successfully drop their pollen onto the female plants as they are budding. Taller males will also have their pollen travel longer distances in the wind.
These male plants also die sooner than females. Luckily for you, you can cut off their flowers and smoke or eat them (after properly drying them, of course). You will be pleased with the resulting high since it will be almost as good as smoking the female buds of your harvest later.
What is pollination
To seed or not to seed? That is the eternal question of many marijuana growers – especially new ones.
When left to their own devices, male marijuana plants will fertilize the females, causing a new generation of seeds to be “born.” While this may appear harmless to the uneducated grower, it can significantly decrease your resulting harvest.
When female plants are fertilized, they will slow down their production of resin, which has a high amount of THC. An unfertilized flower contains the most THC you can find on any marijuana plant. Additionally, unfertilized females can remain in the flowering phase for a long time – between six and ten weeks – meaning a higher amount of these THC-rich buds.
All this means that you will need to decide how many (if any) female plants you would like to be fertilized, and how many you want only for your harvest.
Protecting your females from fertilization isn’t as easy as it sounds, but it is crucial to you getting a successful harvest in the end. The most effective way to do this is simply by uprooting your males and taking them away from your at-risk females.
Ideally, you already took the high male-female ratio into account when you initially planted. Marijuana plants generally are 70% male, so removing all your male plants will reduce the number of plants significantly.
Remember that the end result will be higher, so don’t fear this process. That being said, you better be completely sure a plant is male before removing it from your crop.
There could be nothing worse than to uproot a plant you thought was male, only to discover you just killed a huge female plant that could have significantly contributed to your end yield.
Plenty of growers who only want the marijuana for their personal use will simply allow the males to pollinate the females, and will remove the marijuana seeds from the harvest later.
How to make seeds
This process is best for indoor growers, and it involves fertilizing your plants. To begin with, you must identify which plants are male and which are female (see above).
You will, of course, need at least one male to fertilize your females, but usually one is enough. Choose the one male plant that you think has the best qualities, then remove all of the rest.
The next step is to isolate this male plant so that you can control its lighting separately from the females.
While the females still have continuous light, your male plant should have 12 hours of light and 12 hours of complete darkness. This lighting change will spur the male into flowering and therefore producing pollen.
You should take this pollen and save it since you’re going to need it later. Use a piece of paper to get the pollen from the flowers, and then drop the pollen into an envelope. Stick the envelope in a freezer to keep it fresh.
Meanwhile, keep your female plants in their vegetation phase for as long as possible. Once it is time for the flowering phase to begin, it’s time to use the pollen that has been stored in the freezer.
Decide carefully which females you will want to pollinate. It could be because she exhibits specific qualities you like, or maybe she comes from the same strain as the male plant and it happened to be a great strain, so you want to keep the strain completely pure.
Place the pollen in one cola of the female plant(s). Don’t pollinate flowers on that same plant, and don’t get the pollen in the flowers of the other plants, either.
The process of pollinating your plants must be done carefully. For best results, separate the whole female plant to avoid contaminating the other plants around it.
First, put the frozen pollen into a little bowl, and get a small watercolor paintbrush. Use this brush to glaze the pollen on the top of your female plant’s cola.
After four days or so, put the pollinated female plant under 12 hours of sunlight and 12 hours of uninterrupted darkness. This is the point when you no longer have to worry about cross-pollination since the pollen will be firmly stuck to the cola.
Keep a close eye on your pollinated female to make sure you harvest her seeds at a suitable time. Mature marijuana seeds will not be green, but rather will be some sort of brown color.
Once the seeds are mature enough, simply use your fingers to take them out. Label the container with the seeds and then refrigerate them all. As long as they remain cool and dry, they won’t lose their ability to germinate next season.
In the end, you will both have a nice, high-quality strain of seeds for your next growing period, and the rest of your unpollinated plants will produce wonderful weed. It is a great way to conserve financially while also increasing the quality of your future crops.
At this point, you are probably thinking that the 70% male and 30% female average is pretty unfortunate. Most growers would agree with you. Unfortunately, you don’t have much control over your future plants’ genders when you use regular fertilization techniques.
This is why many take measures to make it more likely that they will get only (or mostly) female plants. One way to sway the odds in your favor is to feminize your marijuana seeds.
In general, you cannot tell the difference between male and female seeds. You also cannot change a seed’s gender. The idea behind feminizing your plants is to maximize the amount of females in your crop since female plants generally have a higher THC content than males, and, therefore, get priority.
Seed feminization utilizes a number of pollination methods to tip the scale in your favor. If you have some extra cash and aren’t feeling up to the challenge, you can also buy already feminized seeds from marijuana seed companies.
Buy feminized seeds
- Every plant will produce flowers
- No time wasted growing useless cannabis
- Grow nothing but harvestable plants
That being said, buying feminized marijuana seeds online can often be hit or miss. Make sure the company you are buying from is reputable. This is the best seed shop online.
There are three types of feminization: silver thiosulfate, colloidal silver and rodelization. Each one, when properly carried out, should end up successfully giving you mostly female plant.
Silver Thiosulfate method
The new innovation if using STS (Silver Thiosulfate Solution) has somehow become commonplace – and it’s a great one because it is highly effective. It has allowed feminized seeds to be found everywhere, meaning that the average grower can buy feminized marijuana seeds.
Better yet, we can all rest assured that they are probably properly feminized, rather than the hit-or-miss feminized seeds market of days past.
So what is silver thiosulfate? It’s a half-and-half combination of sodium thiosulfate and silver nitrate. It simply causes a hormonal reaction of stress in the plant that triggers a change in gender.
So how do you actually create feminized marijuana seeds yourself? It involves a little bit more than drenching your plants in silver thiosulfate, unfortunately…
First you should decide which plants you’re going to use. They should all be female and from one strain, and nearly mature. Then just take one of them, separate it from the bunch, spray it with STS, let it dry, and finally replace it alongside its sister plants.
That plant will start looked very stressed out. It will turn brown and might worry you with how close to death it appears. Just five days later, however, it will begin its revival. In one month’s time, this plant will have finished its transition into being male.
At this point, you can simply shake the new male plant right over those same females, thus pollinating the female plants. Because the new male plant used to be female, the pollen it provides is actually female pollen. That means that, after just a couple of weeks, these pollinated female plants will create feminized seeds.
Although the process seems extremely simple, especially compared to other methods you may have heard of, this doesn’t mean you will have success on your first try. Luckily for you, breeders you might want to buy feminized seeds from always make sure each batch of seeds, along with the entire process, is successful.
They will, therefore, give you seeds that you can depend on. In fact, these days the highest end feminized seeds have a feminization rate of 99% or more, so this method is clearly a huge help to the marijuana industry.
Colloidal Silver method
For this method, you will need a very small amount of colloidal silver (pure silver) and distilled water. Put the former into the latter, then, using a spray bottle, apply the resulting mixture onto your female plants while they are flowering.
The plants will begin to form pollen sacs (which are normally seen on males). The pollen contains genetic material that is actually totally female – making it highly probable that the marijuana seeds the plant produces will be female.
That was the simple way of describing the process. Actually doing it is much more complex and involves many more details. In addition to the pure silver and distilled water, you need a 9-volt battery and connector, alligator clips, and soldering iron. Sound like too much trouble?

Assuming you have no problem with spending the time and money finding these “ingredients,” the next step in the process is to connect the battery and its connector.
Solder the alligator clips onto the red and black wires to form the best electrical current. Then connect these to the silver (probably coins) that you have.
