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.

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

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.

3 Best Ways to Feminize Cannabis Seeds

Most people are already aware that cannabis buds we use today come only from female plants.

Male plants pollinate female plants, which produce seeds upon pollination.

Just like children, some seeds end up being female and some male. That’s just how nature works.

A male plant can pollinate a whole room of female plants. Even if there were 50 plants in that area, all the male plant requires is a bit of wind, and each female plant will end up being fertilized.

Getting only feminized cannabis seeds is not an impossible task, you just have to work around the rules set up by nature.

Why are seeds feminized?

Cannabis growers need seeds that are guaranteed to grow into female plants, in order to avoid pollination of the entire crop.

No one wants seeds in their weed and because of this issue we require feminized seeds.

When you’re certain that all your seeds are feminized, you can grow big crops knowing that your plants are safe from pollination by a male plant.

Breeders and seed producers also want feminized seeds for business purposes, as they’re in very high demand in places where growing weed is legal.

As cannabis becomes legal in more places throughout the world, feminized seeds are the first small-time thing new growers will start looking for.

Reliably producing female plants is of great value in this industry, because only female plants produce flowers with medicinal value.

How to feminize seeds?

When breeding cannabis, growers will intentionally pollinate their females in order to get certain traits in the offspring.

How to Start Your Own Marijuana Seeds Breeding Program?

However, sometimes the breeder isn’t looking to cross two strains in hopes of getting a specific trait.

Once the breeder stabilizes a certain trait, he’ll look to mass produce the offspring with precisely those traits. He may do so by feminizing seeds that the “mother plant” produces.

In the wild and without any human tampering, cannabis plants produce mostly female seeds when they “perceive” that they’re approaching the end of their lifetime.

Feminization is essentially a process of pushing the plant to produce as many female seeds as possible, by making it “think” that it’s approaching its last days.

In order to survive and spread its genetic material as much as possible, plants will mostly make female seeds, and a very small percentage of male seeds, because a small number of males plants can pollinate a colossal number of female plants.

This is why the process of pressuring the plant to produce female seeds en-masse is called feminization.

There are several ways to perform seed feminization. Each one is different, although they all boil down to the same thing — getting female seeds.

Some methods are more efficient than others, which is why they are preferred by numerous producers and growers.

Feminizing seeds with colloidal silver

Colloidal silver is a substance made from microscopic particles of silver, which are suspended in liquid. Particles of silver are less than 100nm (nanometers) in size, and completely invisible to the naked eye.

You can get bottled colloidal silver on Amazon, or you can make it yourself, which is also relatively simple.

If you’re going to use it only a few times don’t bother making it, just order a couple of bottles.

Colloidal silver works by inhibiting female flowering hormones in cannabis. The result of this is that the male hormones dominate, and thus male flowers are produced.

By doing so, you turn your healthy female plants into males. Afterwards, you use the pollen that came off that plant to pollinate the other plants.

After you pollinate the other female plants, they will produce feminized seeds. This technique is reliant and yields female seeds in huge numbers.

Cannabis is known to yield hundreds (sometimes even thousands) of seeds after being pollinated. The colloidal silver method guarantees that you consistently get feminized seeds.

Here’s how to use it:

Spray colloidal silver on the branches every three days prior to switching the lights to 12/12 and continue spraying it until you start seeing first male flowers.

The more you use it, the more pollen sacks you will get. As the plant matures it will produce pollen that should be collected and used to pollinate other female flowers.

Collect the new seeds and plant them to get the next generation of the same plant.

Feminizing with Gibberellic acid

Feminizing with Gibberellic acid is even easier than with colloidal silver.

Gibberellic acid can also be bought in stores, and it’s mostly available in powder-form.

Gibberellic acid isn’t expensive at all, you can order it online or buy an entire box for as low as $15 bucks.

Mix the gibberellic acid with water so it reaches around 100 ppm (parts per million, the instructions on the packaging will let you know what’s what), and spray that water/acid mix on the plant once a day, for 10 consecutive days during the flowering phase, and male flowers will be produced.

After that apply the pollen from the “gibberellic acid” male flowers on other healthy female plants.

Those plants will yield feminized seeds after being pollinated.

Feminizing with the rodelization method

The rodelization method is by far the slowest, the least efficient, and the least guaranteed to work out of these 3 methods.

Rodelization entails not harvesting flowers after they’ve bloomed, but rather forcing the plant to turn male, in order to preserve itself.

After the plant has flowered, you need to leave it like that for another few weeks. The plant will then stress itself and grow a couple male flowers, in an attempt to pollinate itself once more.

If your plant succeeds, you’ll need to wait an additional few weeks to get decent seeds that are ready for sowing. Keep in mind that this method is not as reliable as the other two, and yields a smaller number of seeds.

This is “nature’s way of feminizing seeds”, although like everything else with nature, it takes a lot of time. A lot more time compared to the gibberellic acid and colloidal silver.

All these factors make rodelization the most natural, but for growers by far the worst possible feminization method.

How to make feminised cannabis seeds

Until the 1990s, any cannabis cultivator was aware that, at some point, they had to separate the male and female plants if they didn’t want the first ones to pollinate the latter, which results in plants completely full of seeds. However, those were the days when pioneering seed banks like Dutch Passion were revolutionizing the cannabis scene with the birth of the first feminized cannabis strains, or in other words, seeds that only develop into female plants. At the beginning of the 20th century, many seeds banks were offering this type of seeds, feminized versions of classics strains that had been cultivated during many years as regular plants.

We are sure that by now you’d probably have grown some feminized seeds, maybe even though you are a purist and the fiercest defender of regular seeds. But. do you know where feminized seeds come from? Are you familiar with the processes used by both breeders and growers to obtain them? In this article we explain everything!

Advantages of growing feminised seeds

Indeed, the advent of feminized seeds brought about a genuine revolution within the cannabis sector. Growers were now sure that all their plants would be females, without the need to differentiate between male and female plants or having to remove the males before they could ruin the crops, which offers a number of benefits of significant importance:

  • Space and resources saving: no more growing plants which eventually will be removed for being males.
  • Reliability: it’s not that most plants are female, or that they are genetically more likely to produce female plants. The plants grown from feminized seeds have only female chromosomes (XX), therefore this method is 99% reliable.
  • Sinsemilla plants: by not having males in the grow room, your female plants won’t be pollinated, so they won’t produce any seeds during the flowering period (something that every cultivator wants, unless they want to obtain seeds)

These advantages were of great interest for the growers, and soon feminised seeds accounted for a large portion of the seeds available in the market. In addition, being able to use only female plants (generally known and selected clones) to produce seeds had another great advantage for seed producers and breeders of new varieties: they no longer need to keep males in their gene pools! And not only that. from that moment on, any female plant they could get their hands on could be used as a male to pollinate other plants, thus exponentially increasing the possibilities of creating new crosses.

It is not surprising, therefore, that at present, feminized seeds represent virtually all the seeds in the market, since they offer a number of significant advantages for both professional and home growers and breeders, for photoperiod and autoflowering plants. The main disadvantage of this method is a well known and hotly debated issue: the growers who buy this type of seeds cannot produce their own seeds in the absence of male plants, so the only way they can manage it it’s using the same process to obtain this type of seeds. But. what are these processes and what are they based on?

Female crosses: feminised cannabis seeds are born

As we’ve already mentioned, feminized seeds are the result of a process that reverses the sex of a female plant, that is, she is forced to produce male flowers. This way, and once into flowering, the female chosen will start to develop what we know as male flowers (stamens and anthers), which, just like male plants, will release the pollen that will pollinate the female plants. What is then the difference between a male plant and a reverted female plant?

The sex of cannabis plants is determined in the same way as ours, through the so-called sex chromosomes or genosomes. Male plants have a couple of different sex chromosomes called “XY” or heterogametic, while female plants have two chromosomes called “XX” or homogametic. When crossing a male (XY) with a female (XX), we will obtain around half of the plants of each type in their offspring. In other words, when a breeder uses a male and a female plant, the seeds produced by them will be approximately 50% males and 50% females.

After this explanation, many of you will have already figured out that if we cross two female plants (reversing the sex of one of them to force it to produce pollen), the result will be seeds that will produce female plants, as there are only female sex chromosomes in the equation. If crossing XY with XX produced 50% of each class (male and female), crossing XX with XX will produce plants that only exhibit chromosomes XX, that is to say, female plants. No matter how many times we “transform” a female plant into a male plant, we won´t be changing their genetic composition, which will still be female or XX. This way, the pollen produced by this plant will pass down female sex chromosomes exclusively.

Feminised seeds grown indoors, 100% female plants

As you can see, and although we normally use the expression “reversing the plant sex“, that is not exactly what is done, because the sex chromosomes of the female plant (XX) have not changed, even if we managed to produce male flowers. This “sex change” of female plants can be achieved in a number of ways, but usually with the same goal: to reduce the level of ethylene in plant tissues and/or inhibit the ethylene action, which makes the plant develop male flowers on entering the flowering period, as if it were a male from regular seeds. This is because ethylene is a natural regulator of the sex expression in plants!

Let’s see now the most popular ways to reverse the sex of a female plant in order to produce feminized seeds.

Methods used to produce feminized cannabis seeds

There are several ways to secure that a female plant produces pollen, and almost all of them require some type of chemical that is often sprayed on the plant. Once sprinkled with the chosen product and under a flowering photoperiod, the plant will flower normally, but as a male instead of female, producing ‘feminized’ pollen (which only contains chromosomes XX) that can be used to pollinate other females in order to produce seeds. These are some of the most commonly used techniques:

Stress or rodelization

One of the first methods used to obtain seeds that produce female plants was stress or rodelization. There are several ways to stress the cannabis plants to make sure they develop male flowers, such as through temperature, nutrition, photoperiod, and pH. However, supporters of this technique often prefer something as simple as delaying the harvest 2-3 weeks in order to force the plants to develop a few male flowers without stressing them as much as with any of the other methods we have mentioned.

Although this action will produce far less pollen than other techniques like STS, it will be enough to obtain a handful of seeds for the domestic growers to try to create their own feminized crosses. Also, the great advantage of this technique is that is 100% natural, and it doesn´t use any chemicals. It is an excellent alternative for anyone who just wants a few seeds and wishes to keep it simple without any formulas or laboratory products. However, bear in mind that this is the only method listed in this post that may produce some plants with hermaphroditic traits.

Male flower produced by rodelization

STS or silver thiosulfate solution

Without any doubt, one of the most commonly used methods for both producers and seed banks. This is a solution made of distilled water, silver nitrate and sodium thiosulphate (sometimes called sodium hyposulphite) that, after being sprayed on the female plants, inhibits their ethylene action resulting in the formation of male flowers once flowering has been induced. STS is relatively easy to prepare, although its lifespan after combining the two components is quite limited, barely a few days as long as it´s well preserved (in a dark and cool place).

It is important to mention that you must not consume any part of the plants sprayed with this type of product, although that would be weird, as the plants have “become” males and won´t produce any buds. Nevertheless, you shouldn’t use the reverted plants to make resin extracts; the best thing is to discard them after harvesting the pollen. Both components, sodium thiosulphate and silver nitrate, are also used for photo-development.

Colloidal silver

This is another way to revert the sex of the plants, but this time using a solution made of 30ppm colloidal silver (that you can easily find in many pharmacies and also online) and distilled water. The solution must be applied for a few days until the plant starts producing male flowers, something that it´s not necessary with STS, where in most cases one single application is enough.

Colloidal silver is formed by electrically charged silver nanoparticles and has antibacterial and antifungal properties. This product was introduced in the market in 1980 for therapeutic use. However, as with STS, you should get rid of the sprayed plants once their pollen is harvested, as colloidal silver is absorbed systemically by the plant and remains in its tissues.

This sativa plant treated with STS started flowering as a female but soon developed male flowers

Silver nitrate

This is a method researched by Mohan Ram, who also conducted extensive investigations on plant sex reversal with STS. According to his findings, sodium thiosulphate (STS) is more effective in producing male flowers and viable pollen in female plants. Probably because of this, silver nitrate is mixed with sodium thiosulphate, instead of using it in isolation.

Gibberellic acid

Gibberellins are plant hormones that help regulate various processes related to the development of the plants. There are several types of gibberellins available in the market, although the most common and effective is gibberellic acid or GA3 (Gibberellin GA3). This product is used in a very similar way to colloidal silver, sprayed on the plants during several days before switching the photoperiod over to flowering.

It is worth stating that one of the side effects of gibberellic acid is a significant stretching of the treated parts of the plant, so don’t be surprised if this happens to your plants! The recommended dose to achieve the best results is approximately 100ppm.

Urban legends and lies about feminized seeds

Despite the fact that, after two decades of cannabis cultivation, many of the false myths surrounding feminized seeds have been debunked, from time to time we still hear some arguments like the ones shown below. As is often the case, many of these stories are spread by people who have never grown this type of seeds or have none or very limited experience with them. Ignorance is always a bad thing, and that’s why we want to emphasize several points in relation to feminized seeds and the myths that often go with them; myths such as the following:

Feminized seeds produce hermaphrodite plants:

The problem with monoecious hermaphrodite plants has more to do with the parents used (and if they exhibit any hermaphrodite trait) rather than with the type of seeds produced. If to create a feminized seed you use a female plant with a tendency to produce male flowers, part of its offspring will likely inherit that characteristic, whether the said female plant is used as a pollen donor (after reversing its sex) or as a recipient of pollen (letting it flowering as usual). Yet the same thing happens when producing regular seeds: if the male or female parents are not stable in this respect, neither will be their offspring (or at least part of it).

Marijuana and hermaphroditism

Many growers have been surprised by the presence of hermaphrodite plants in their marijuana crops. In this post we will tell you how to detect them and how to proceed if you find a hermaphrodite cannabis plant in your growing space. We will also discuss the causes of this hermaphroditism.

Feminized seeds produce mutant plants:

Nothing could be further from the truth. It is true that sometimes some plants develop weird traits or mutations, although this also happens with regular seeds. Unfortunately, there seems to be not enough studies comparing the ratio of specimens with mutations of one or other type of seeds; however, given the millions of feminized seeds that have been germinated in the last 20 years, if mutations would pose a problem, the quantity of feminized seeds sold would certainly not be so high, and this would be a “public security” issue within the cannabis sector, both for the growers and the producers of the seeds.

Feminized seeds have chemicals:

This is another lie that some people believe. As it’s been mentioned before, a female plant is sprayed with some chemicals in order to inhibit its ethylene action. After a few weeks of this and once in the flowering period, the plant will produce male flowers and pollen, which will be harvested to pollinate the female plants designated to produce seeds. Once the seeds are formed, they are collected and packed immediately, so they don’t come into contact with any chemicals or the plants that produce seeds, nor, of course, with the seeds themselves. Also, to produce cannabis seeds, you normally need two separated indoor cultivation areas, one for the reverted plants (treated females) and the other for the females to be fertilized to produce the seeds, so the latter can’t get “contaminated” with any chemicals.

Feminized seeds are GMOs:

Once again, this is a false statement. We have already pointed out that by using these sex reversal techniques we inhibit the ethylene action in the female plant, and under no circumstances the seeds (or plants) are genetically modified. The sex chromosomes of the female plant converted into a male plant are still female (XX), nothing has changed at a genetic level.
