5 Steps to Feminized Seeds – Learn how to force female plants to make pollen and create feminized seeds

Introduction to Feminizing Your Own Cannabis Seeds

First of all, what are “feminized” marijuana seeds? Feminized seeds are seeds which have been created by breeding two female plants together. Because there are no male parents, all the resulting seeds end up being bud-bearing female plants. With feminized seeds, you know you can always count on every plant to produce buds, and don’t have to worry about removing male plants (which cause lower yields and seedy buds if they’re left among your female plants). Learn more about male vs female cannabis plants.

Feminized seeds come from two female plants being bred together, causing all offspring to be female

Feminized seeds are commonly available from seed banks for nearly every popular or famous strain. Breeders understand that a lot of people just want to grow plants for buds, and don’t care about making a robust breeding program (which is one of the main reasons growers want male plants).

So how do seed banks feminize their seeds? How can you breed two female plants together?

The main idea is to force a female plant to produce pollen sacs like a male plant. These male flowers (growing on a female plant) create pollen, which can be harvested and used to pollinate another female cannabis plant. The resulting seeds will all end up being female. Can feminizing seeds cause hermaphrodite plants?

Growers can force a female plant to make pollen sacs, and the “feminized” pollen produced can be used to fertilize another female plant

How do you force a female plant to make pollen?

There are two main ways to make feminized pollen:

  1. Induce feminized pollen chemically (Recommended) – This is the “professional way” to feminize seeds, and is how most reputable seed banks and breeders create feminized seeds to sell to the public. Substances such as colloidal silver and gibberellic acid are used because they cause a female plant to produce male pollen sacs if bud sites are drenched daily for the first 3-4 weeks after the switch to 12/12. This article will give you step-by-step instructions on how to feminize cannabis seeds using this method.
  2. Rhodelization (Not Recommended!) – In the wild, some female cannabis plants will naturally start making male pollen sacs or “bananas” which can self-pollinate the plant. This happens if the plant is stressed, or if the plant is not harvested in time and buds start to die of old age. The plant is basically doing everything it can to save the next generation. This method is “natural” and these seeds will all end up being mostly female, but the problem is you’re selecting for plants that naturally hermie (grow both male and female sex organs) without any chemical induction. This means the resulting seeds are much more likely to turn hermie in natural conditions too. That’s a problem if you don’t want seedy buds every time you harvest. For that reason, it’s highly recommended you don’t feminize seeds this way, and it’s a good idea to toss any and all seeds that are the result of natural herming.

Read this article for more in-depth discussion about the pros and cons of each method, and how to avoid hermaphrodite plants when producing your own feminized seeds.

Overview: How to Make Feminized Seeds

1.) Buy or Make Colloidal Silver – The article below will teach you how to make colloidal silver at home, as well as show you where to buy it if you don’t want to make it (it’s actually pretty cheap!). It’s basically a solution of silver suspended in water and is available online and in health stores as a dietary supplement.

What about gibberellic acid? I’ve seen with my own eyes that the colloidal silver method works for making feminized seeds, but I don’t personally know anyone who has tried making feminized seeds with gibberellic acid. From what I understand it can be used exactly the same way as colloidal silver to induce female plants to produce pollen, but I’m not sure exactly how to prepare a gibberellic acid solution that works consistently.

2.) Spray the bud sites of your known female plant daily during first 3-4 weeks of the flowering stage (until pollen sacs form and start splitting open) – After switching to a 12/12 light schedule, choose bud sites on your known female plant, and spray/drench them daily with colloidal silver (or gibberellic acid). As the treated flowers develop, they will form into male pollen sacs. Untreated bud sites on the plant will form into female buds as usual; however, these buds are unsafe to smoke unless you’ve been very careful to make sure they didn’t come into contact with colloidal silver or gibberellic acid during the feminization process.

3.) Harvest “Feminized” Pollen – When pollen sacs are ready to be harvested they swell like a balloon and start to open up. Make sure not to harvest early and also make sure to keep spraying the bud sites daily until this point or you might end up with empty pollen sacs! When the pollen sacs are ready, the leaf section protecting the pollen will start to crack. At this point, it’s time to collect the feminized pollen. One of the easiest ways to do this is to collect the pollen sacs directly and let them dry for a week. At that point, they can be placed in a bag and shaken to easily collect all the pollen.

4.) Pollinate Another Female Plant – At this point, take the feminized pollen you’ve collected and use it to pollinate a female plant that has been flowering for about 2-3 weeks (full detailed instructions with a video on how to do this below). Although it’s possible to pollinate the same plant as the original, it’s not recommended in part because the timing doesn’t match up (attempting to pollinate buds too late in the flowering stage leads to reduced seed production). It’s best to pollinate a different female plant that you started budding a few weeks after the original. This increases the number of seeds produced as well as gives the new female plant enough time to develop them to maturity. It also increases genetic diversity compared to self-pollination.

6 Weeks to Harvest Seeds – After about 6 weeks from pollination, the calyxes on the buds of your female plant will be swollen and fat. You know it’s time to harvest your seeds when they start bursting out. At this point, it’s time to congratulate yourself because you’ve got feminized seeds!

Now that you’ve gotten the overview, here’s the feminization process with detailed step-by-step instructions…

Step-By-Step Instructions (with pics!)

1.) Buy or Make Colloidal Silver (or Gibberellic Acid)

Where to get Colloidal Silver (your options):

  1. Buy Ready-To-Use Colloidal Silver: Colloidal silver is sometimes used as a dietary supplement, so it’s relatively easy to find (never take it without talking to a doctor first though!). If you’re purchasing colloidal silver, try to find a solution that has at least 30 PPM (parts per million) of silver or higher.
  2. Buy A Colloidal Silver Generator Kit: If you plan on feminizing a lot of seeds, you may want to invest in a generator kit so you can easily make your own endless supply of colloidal silver.
  3. Make Your Own: You can make your own colloidal silver generator at home. The following diagram illustrates what you need to do.

Note: You can purchase gibberellic acid online (a gibberellic acid solution can be used the same way as colloidal silver for feminizing seeds). However, I do not have experience with the gibberellic acid method and don’t know the best way to prepare the solution.

2.) Spray the bud sites of your known female plant daily during first 3-4 weeks of the flowering stage (until pollen sacs form and start splitting open)

When you’re ready, change to a 12/12 light schedule in order to initiate flower formation. For photoperiod plants, wait until your plant is 5-6 weeks old before initiating the flowering stage. Some young plants seem to have trouble (and take much longer) to go through the feminization process, and their pollen may not be as fertile, so start with a more mature plant.

As soon as you change the light schedule (and maybe even a day or two before) start spraying your plants thoroughly with colloidal silver at every bud site you want to form into pollen sacs.

Spray bud sites thoroughly, drenching them with colloidal silver every single day

The above pic shows you where pollen sacs form on the plant (same places female buds form)

Important! Keep spraying daily until pollen sacs open up. Don’t stop spraying early, even if pollen sacs appear to be already formed, otherwise they may not produce much pollen!

A one-hand pressure sprayer / mister is really helpful for spraying bud sites evenly and thoroughly

You can choose to treat a single bud site or all the bud sites on the plant. Any untreated bud sites will develop into female buds as usual. If you want to smoke these buds, it’s incredibly important to avoid letting them come into contact with colloidal silver as that’s not safe to smoke. (Don’t worry, feminized seeds don’t contain any silver). I highly recommend letting the whole plant be your test subject so you don’t have to worry about that 🙂

Note: If you’re feminizing an auto-flowering plant, start spraying daily when the plant is about 20 days old from seed. This is when most auto-flowering cannabis strains start making flowers.

3.) Harvest Your Feminized Pollen

When pollen sacs are starting to crack and look like they’re about to open up (or if you can see one has already opened) then your pollen is ready for harvest!

When pollen sacs are cracking and opening up, you’re ready to harvest your pollen!

Pollen spilling onto a nearby leaf

One way to harvest your pollen is to gently and carefully remove all the pollen sacs. Let them dry for a week, and then put them in a resealable bag. If you shake the bag the pollen should easily spill out. You may need to cut a few open yourself.

How to Store Feminized Pollen: Moisture is your main enemy when storing pollen. It can help to double the mass of the pollen collected by adding regular cooking flour. This absorbs moisture during storage and as an added bonus, it will make application easier when you get to pollinating. If you triple-bag the pollen-flour mixture and stick it in the freezer (with a good nametag so you know where the pollen came from), your pollen can be stored for a year or longer.

4.) Pollinate Another Female Plant

When your chosen mother is 2-3 weeks into the flowering stage, take a paintbrush and ‘paint’ your feminized pollen on the developing bud sites you want to pollinate. Bud sites (for both male and female plants) are located wherever you can see leaves meet a stem.

Only the buds that come in contact with pollen will grow seeds. You can choose to pollinate all of your buds or just a few on the plant.

Make sure that you’re touching all the female pistils/hairs with your pollen. Here’s a little video showing you exactly what this looks like!

6 Weeks to Harvest Seeds

It usually takes about 6 weeks for your feminized seeds to fully develop. Some plants are literally dying right as the seeds become ready, so to get the most viable seeds, you need to try to keep it alive until the seeds actually start dropping. The seeds can be used right away, or stored in a cool, dry place for a few years. Don’t forget to label them with the date!

Picture Journal of Making Feminized Pollen with Colloidal Silver

This grower initiated the feminization process on a seedling that was only a few weeks old. As a result, the plant wasn’t able to get big enough to produce many pollen sacs. You will get even better results if you start with a plant that is at least 5 weeks old 🙂

October 18 – Plant right before the switch to 12/12

October 27 – After being drenched with colloidal silver daily for a little over a week

October 30 – Pollen sacs are forming

November 15 – Pollen sacs appear to be almost fully formed and are swelling in size, but haven’t opened up yet. Don’t stop spraying colloidal silver or you may end up with empty sacs!

November 27 – Pollen sacs are opening up! Collect the pollen before they’re all open!

FAQs – Frequently Asked Questions

How can I identify plant gender before the plant actually starts flowering? (Besides using feminized seeds)

There are a few ways to identify plant gender before the plant actually starts flowering, and each is helpful in different situations.

  1. Start with a clone – A clone is an exact copy of another plant. If the “mother” of the clone is a female plant, it means the clone is also female
  2. Look at preflowers (identify plants when they’re 3-6 weeks from seed) – If you know where to look, cannabis plants will actually reveal their gender in the vegetative stage when they’re just 3-6 weeks from seeds. Male plants usually show their gender by 3-4 weeks and female plants usually show their gender around week 4-6 from seed. Learn how to determine the gender in the veg stage by looking at preflowers.
  3. Test the leaves of your seedling – It’s possible to send in a leaf from a young cannabis plant to a specialized testing company, and they will be able to determine the gender as soon as 3 weeks from seed! Although I haven’t used any of these companies and can’t recommend any in particular, here’s a link to one example just so you can see what I’m talking about. From talking to other growers who use this method, it appears to be very accurate.
  4. Take a clone and force it to start flowering – if you take a clone from a vegetative plant, you can force that clone to start flowering and reveal its gender. You’ll know the gender of the “parent” plant by the gender expressed by the clone. In my opinion it’s better just to look at the pre-flowers since they’ll usually tell you sooner than if you use this method (in this case you have to wait for the seedling to get old enough to clone, then wait for the clone to make roots, then wait for the clone to start flowering – which usually takes weeks longer than the much easier pre-flower method).
  5. Look at the seed itself – Some growers swear by this method (if someone knows the author of this popular but anonymous picture that has been circulated on the internet since at least 2008, please let us know!). The idea is to look at the seed’s characteristics because to some extent, some seeds look “more female” than others. According to people who use this method, it’s better than random guessing but unfortunately in the best-case scenario, even the growers I’ve talked to who have experience using this method say it only has up to 70% accuracy. That means about 1/3 of “female” seeds end up being male. It also creates false negatives, which means that about 1/3 of the “male” seeds you’re throwing away are actually female. It’s better than 50/50 but when using this method; it’s not a way to ensure that all plants are going to be female. Personally, I do not recommend using this method as a way to identify gender. I believe all the other methods are much more accurate and depend less on needing experience!

Can I Make a Breeding Program Using Just Female Plants and Feminized Seeds?

Yes, it’s possible to use just female plants and feminized seeds for further breeding, with one major caveat.

Without careful and thorough testing, it may be possible to accidentally select for cannabis plants that tend to herm (make male flowers or pollen) and cause seedy buds when you don’t want them to.

For each possible “mother,” clones should be grown in several different environments and tested thoroughly to make sure that the mother plant does not have any tendency to make pollen naturally in normal or stressful conditions. It’s okay if plants grow pollen sacs if induced chemically since that is very unlikely to happen in someone’s garden on accident, but you don’t want plants that will start growing male parts on their own without chemical induction. Thorough testing of plant hardiness is always important when breeding, but it may be especially important when breeding feminized seeds together.

Are there other reasons I should avoid breeding seeds without males?

The most common reason growers say you shouldn’t do this is because it’s “unnatural” or doesn’t “seem right.” Some growers say you need male plants for genetic diversity. I’ve also heard growers say that the resulting plants will be weaker, sterile, less potent and once someone even told me that resulting plants “will be worse in every way.”

As of yet I haven’t seen any of these claims backed by actual personal experience, or any real-life examples showing why using feminized seeds is not a viable way to breed new strains.

To those who say this type of reproduction just doesn’t seem right, the evolutionary strategy of plants using only female and hermaphrodite plants to breed is actually pretty common and is known as gynodioecy. One example of a plant that only reproduces this way is a flower found in Canada and the US called Lobelia siphilitica, also known as the Great Lobelia. Obviously this reproduction method isn’t exactly the same as artificial feminization since the pollen production is caused naturally instead of induced chemically, but examples of gynodioecy show that a female flower-based breeding population can exist in the wild even when no plants are purely male.

The Great Lobelia naturally reproduces using only female and hermaphrodite plants. This is similar to the cannabis feminization process because it results in a population of plants that all primarily grow female flowers, with no pure male plants

When it comes to genetic diversity, the ability to cross out to thousands of different cannabis strains allows you to dramatically increase the gene pool without using male plants.

So those are my answers to the common objections of a feminized seed-based breeding program, however I am just a theory-crafter when it comes to this topic.

It certainly seems possible that a feminized-only breeding program could run into unforeseen problems down the road, but as far as I know there isn’t any evidence of that so far.

Although I have a few anecdotes from growers who have used only feminized seeds for a few generations, it would be much better to share information from someone who has conducted plenty of testing over several generations. We’d love to hear from you if you have bred more than a few generations using only feminized seeds and want to share your experience!

What are positive aspects of breeding two feminized seeds together?

Besides not having to worry about male plants in the next generation, the main advantage of doing this is you have a much better idea what you’re working with when it comes to producing the type of buds you’re looking for. When you’re growing a male plant, it has several genes it will pass to its offspring that has to do with how buds develop, but since it’s a male plant those genes aren’t expressed and it’s hard to figure out what they are.

Historically, the way to learn more about the “hidden genes” contained in a male plant is to breed it to several well-known female plants, and see how the offspring compare to each other. The genes that don’t come from the known mother plant are assumed to come from the male. Another way of going about this is to take several clones of the same well-known female plant, and breed them with many different male plants to see which ones produce the best offspring.

After testing with several pairings, you start to get an idea of the hidden genes a male plant has to offer to its female offspring. This time-consuming process of documenting and identifying good male plants is why proven stud male plants are one of the most valuable and closely guarded types of clones available today.

But the process of finding the right “father” is a little different when you start with two female plants. In this case you already know quite a bit about the genes of both parents because you can just look at and test the buds of both plants directly. This allows you to pinpoint desirable genes with less guessing and much less time spent growing out and cataloging plants!

Why even have male plants then?

In nature, male plants are very effective at increasing genetic diversity by ensuring cross pollination. With only purely male and purely female plants, every resulting seed will have two different parents.

Another big advantage in the wild of having separate female and male plants is sexual specialization. In other words, plants are able to evolve male and female traits separately, so each type of flower can become more specialized at its unique “job.”

However, this isn’t the only successful breeding strategy for plants. In fact, only 6-7% of plants have completely separate male and female plants like cannabis plants do (known as dioecious plants). Most plants grow some mix of male and female flowers on each plant, with different combinations offering different evolutionary benefits.

You might enjoy this scientific article if you want to learn more about the evolution of sex determination in plants and animals: Sex Determination: Why So Many Ways of Doing It?

And although most cannabis strains (at least the good ones) display either purely male or purely female flowers, there are some wild populations (and some strains of hemp) that regularly produce plants with male and female parts on the same plant.

When it comes to artificial selection for breeding new strains, the grower is in charge of cross pollination, so there’s no need for the plant to specialize in male parts. Pretty much the only thing most growers care about is how female flowers develop. So (unlike in nature) growers have the freedom to choose plants that improve female buds without even having to consider how it might affect male plants.

Can feminizing seeds result in hermaphrodite plants?

The answer is yes. If you do it the wrong way then feminization can lead to plants with an increased chance of herming. However, with a well-tested and well-bred feminization program, one of the main goals is to breed out any plants with hermaphroditic tendencies that show up under normal conditions. When you buy feminized seeds from trustworthy breeders, you can count on the fact that every plant will end up growing only female flowers and that’s it.

This is a relatively big topic with a lot of controversy so I wrote a whole article about it if you want to check it out!

Can I pollinate the same plant I collected the pollen from?

Yes, it’s possible. However, it’s not really recommended because for one, the timing doesn’t match up. By the time your pollen is ready to use, your original plant will already be several weeks past the optimum pollination point. It’s best to pollinate a female plant that has only been flowering about 2-3 weeks. It’s also possible to run into unwanted side effects from self-pollination/inbreeding.

One thing to keep in mind is even if you pollinate a plant to itself, the resulting seeds are likely not going to be exact copies of the original (unless the original plant is extremely inbred). The resulting seeds will be a mix of both the mother’s expressed genes and her hidden ones.

How to Feminize Marijuana Seeds

Growing marijuana can be fun especially when one uses feminized marijuana seeds because this means they won’t have to worry about dealing with males when harvest season comes. Knowing how to feminize seeds is a huge plus as it ensures that one will always have a steady batch of female seeds available.

In this article, we are going to learn how to feminize cannabis seeds as well as the different methods used to do this. It is going to take a bit of work, but the results in the end will make everything worth it.

Male and Female Cannabis Plants

Before one can even think about feminizing marijuana seeds, one must first know and understand the difference between male and female plants. Many cannabis growers are unable to tell the gender of their plants, which is a common problem. Understanding the difference between male and female cannabis plants requires one to know the hereditary functions of both.

Female plants produce flowers when they mature, and these flowers are the cannabis once they become dry and ready for harvest. Male plants, on the other hand, have no flowers but instead, exude pollen that pollinates other female plants.

Pollinated female plants will produce seeds instead of cannabis. This also causes the female plant’s THC levels to drop, and its buds will also be full of seeds. Those who wish to grow cannabis need to have female plants and remove any male plants in the grow room. But how can one tell whether a cannabis plant is male or female?

Male Plants

Male cannabis plants appear tall and thin and only have a few leaves and branches. Male plants look “unhealthy” because of their lanky appearance and height. The nodes of male marijuana plants have round balls, have low THC levels, and do not produce flowers. Male cannabis plants are only needed by growers who want to produce their own seeds. Male plants should be removed from the grow room if one wishes to grow cannabis.

Female Plants

Female plants are the exact opposite of their male counterparts as they appear healthier and have more branches. Not only do female plants grow in height, but they also grow in width, too. Little hairs appear on the ends of female plants’ branches right around the start of the flowering season.

Females can also be distinguished by their nodes which look tiny balls with a bunch of little hairs growing out of them. Female cannabis plants produce flowers and usually have high amounts of THC. Raising feminized marijuana seeds has a 95% chance of producing female plants.

Alternative Methods to Produce Feminized Seeds

Growing a crop from feminized marijuana seeds is saving up space and ensuring a mostly-female harvest. Feminized seeds are an efficient option for indoor and outdoor growers. Resources, grow space, and time will not be allocated to plants that will end up getting discarded after the 12-12 light cycle. Outdoors, female plants provide one with a good way of preventing gorilla crop pollination.

Besides buying the seeds from trusted seed banks, there are also other alternatives that growers can use to produce their own supply of female seeds. Just think of how awesome it must feel to produce a batch of Bruce Banner strain seeds without having to purchase from a seed bank.

Here are the 3 most common methods used in creating feminized seeds:

The Colloidal Silver Method

Source: Green Point Seeds

Colloidal silver is a substance that is produced by suspending microscopic particles of silver in liquid. These silver particles measure no more than 100 nanometers and cannot be seen by the naked eye. Bottled colloidal silver can be purchased online through shops like Amazon or made at home which is a relatively simple task. If one is looking to use it for only a few times, then it is best to just purchase the colloidal silver instead of making it on one’s own.

The substance works by impeding the cannabis plant’s female flowering hormones. This results in the male hormones dominating the females, and in turn produces male flowers. This basically turns the female plants into healthy males. The pollens that come from the male plants are used to pollinate other female plants which produce female seeds after.

When pollinated, cannabis can yield hundreds (and sometimes thousands) of seeds – using the colloidal silver method guarantees that one consistently gets a healthy amount of feminized seeds.

To use this method, spray the colloidal silver on the plants’ branches every three days before switching to the 12/12 light cycle. Continue spraying until the first male flowers become visible. The more one uses colloidal silver, the more pollen sacs are produced. As the male plants mature, it will produce pollen that can be collected and used on the females.

Gather the new batch of feminized seeds and raise them to get a new generation of female crops in your garden.

The Silver Thiosulfate Method

Silver Thiosulfate, or STS for short, is a chemical mix that is used for producing feminized pollen. STS is the most reliable and commonly used method for creating feminized seeds. Female marijuana plants rely on ethylene production to form flowers. No ethylene means the female plants will produce males rich in feminized pollen.

STS suppresses the production of ethylene in plants. When properly applied on cannabis plant’s bud site, the plant does not produce ethylene. Again, male flowers are formed when ethylene is absent.

Making STS

Making STS might seem complicated at first, but it’s actually as simple as mixing a powdered juice drink. Silver thiosulfate is mixed up into two separate parts known as “stock solutions.” The stock solutions are categorized as A and B. Solution A consists of a mixture of distilled water and silver nitrate, while solution B consists of distilled water and sodium thiosulfate.

These solutions can be stored in light-proof bottles and get refrigerated and sealed for several years without getting damaged. When both A and B are mixed together, the resulting solution is diluted using distilled water before it is applied to the plants. Store the STS (both diluted and full strength) away from all sources of light. When stored properly it can be preserved for up to 9 months but using a freshly mixed batch of STS offers a better chance at getting great results.

Make sure to have protective materials such as goggles, gloves, and a safety mask when mixing the solutions. STS can leave behind burns on one’s skin and is also toxic when inhaled. Remember not to use any metallic objects when producing STS as these can reduce efficiency and alter the material’s composition. Only use plastic when making STS.

How to Mix STS

The first thing must do is to put 20 ml of distilled water into a plastic cup. Dilute at least 300 mg of silver nitrate into the cup of distilled water. Silver nitrate can be obtained from Argenpal sticks which are available in online pharmacies. Each stick of Argenpal contains 42.5 mg of silver nitrate. The silver nitrate is found at the tip of each stick. Argenpal is a medication that is used for getting rid of warts.

Get another plastic cup and fill it up with 30 mg of distilled water and 1.3 mg of STS. Mix slowly and carefully until the STS has dissolved. Now, mix the contents of both glasses using a plastic spoon and make sure to wear gloves and a mask while doing it.

If done right, the user will end up with 50 ml of silver thiosulfate, which is too potent to use on cannabis plants. One can tone down its potency by adding the STS to 400 ml of distilled water in a bottle and shake the mixture until it is completely mixed. This now leaves one with 450 ml of STS which is still too concentrated for use on plants.

To further remedy this, take 100 ml of the mixed STS and add it to 400 ml of distilled water. Now, one has 500 ml of usable and plant-friendly STS. Use the mixture on the same day it is made to get maximum efficiency. When not in use, store the STS away in a cool, dark place. The mixture can last for up to 15 days, but each passing day makes the mixture less potent.

Using STS

Spray the STS on the leaves of your cannabis plants until they are fully covered in the mixture and dripping. It’s recommended to remove the plant that one intends to spray from the grow area to avoid spraying the STS on the other plants. It’s best to begin spraying 4 to 5 days after flipping your lights just as they get turned off. This allows one to spray the plants without the fear of causing damage to them. Respray the plants using the same process after 10 days.

Male flowers with pollen sacs will appear on the sprayed plants, and this pollen can be used on other plants which will produce seeds with all-female genes. One can use the pollinated plants and make extracts from their resin because the number of seeds that they produce is going to make them useless. The sprayed plants will eventually have to get discarded as they’re going to become too toxic to be used.

When making feminized seeds using STS, one can combine different strains, thus resulting in a feminized hybrid that one has made himself, which is very satisfying. For instance, one can combine a K Train strain with a Critical Cure strain and get a different phenotype with various structures and qualities.

The Rodelization Method

This is an all-natural method of creating feminized seeds which also happens to be the simplest one as well. However, its biggest drawback is that it’s unreliable and may not produce that many feminized seeds. The basic premise of this method is that some female cannabis plants will begin growing male pollen sacs if they are left in the flowering state for too long. This is a last-ditch effort by the cannabis plant to self-pollinate so it can at least produce a few seeds near the end of its life cycle.

One can collect the male pollen sacs and use them to pollinate other feminized plants. To do this, one should evenly cover the female’s buds with pollen 2 to 3 weeks into their flowering stage. Females that get pollinated in this manner will begin producing all-female cannabis seeds. One must observe caution when pollinating plants through the rodelization method so that one will only pollinate some of the plants while leaving the other ones alone so they can be used later for personal consumption.

The main concern with using this method is that some cannabis strains are unable to naturally grow male characteristics. The rodelization method also requires one to look for plants that have a natural tendency to show their male characteristics. Doing this will give the plant a chance of producing offspring that have male characteristics as well.

Even if one were to get male pollen sacs through this method, the amount of pollen produced is much lower compared to typical male cannabis. And since this method is all-natural, one can easily implement it in an organic grow.
