What Are Feminized Cannabis Seeds?
This article is sponsored by Kannabia Seed Company, an award-winning cannabis seed company headquartered in Spain. Using only the highest quality genetics on the market, their grower-oriented approach has made cannabis cultivation simple and satisfying for growers of all skill levels for years.
Anyone who’s ever savored a joint owes their enjoyment to the fruits of the cannabis plant, but moreover, to the female of the species. That’s because only female cannabis plants produce the cannabinoid-rich flowers that deliver the flavors and effects consumers look for.
This is why many North American growers are turning to feminized seeds—cannabis seeds that carry only female genetics, and can be relied on to produce only female plants. By creatively applying technologies to seed feminization, modern breeders like Kannabia can ensure female genetics in seeds with a nearly 100% success rate.
Male vs. Female Cannabis Plants

Cannabis plants that are pollinated naturally or with traditional breeding techniques can produce both male or female seeds. These are known as regular seeds and, as in most species, they occur with about an even split between the two sexes. That means cannabis cultivators starting with standard seeds have about a 50% chance of yielding a female plant from each one.
As a result, growing cannabis from regular seeds isn’t very efficient—it’s akin to running a bakery that has to throw out every second loaf of bread. Growers working from regular seeds have to account for the fact that roughly half of their plants could be males. While those plants are of some value to breeders, folks growing for flower won’t find much to like in them, and too many male plants can spoil a grow.
Traditionally, the solution to this has been an inelegant one, with many cultivators planting at least twice as many seeds as they hope to harvest with the assumption that about half of them will be useless. However big a harvest you’re looking for, using regular seeds means you’ll have to plant twice that many seeds.
Why Grow From Feminized Cannabis Seeds?

There are numerous advantages for growers who start their garden using feminized seeds. By removing the guesswork of germinating regular seeds, feminized seeds streamline the growing process, saving space and time.
That efficiency is key for medical cannabis patients and hobby growers. Since most cannabis regulations limit plant counts, growers cultivating a small crop of cannabis for personal use want to ensure they’re getting the most out of their grow.
Male plants don’t just take up space in a garden, either. They can also sap time and resources from growers. When male and female plants are both present, growers need to cultivate both until their sexes are clear. While some strains will show early signs of their sex before flowering begins, most cannabis plants don’t begin to express their sex until they start to mature past the vegetative stage.
This change occurs when the photoperiod, or amount of light and dark that the plant receives, changes to 12 hours of light and 12 hours of dark. In outdoor gardens this change can happen naturally with the seasons or, in more controlled environments like indoor gardens, by human intervention using light timers.
Once those plants are old enough, growers have to go to the trouble of actually determining their sex, monitoring each individual plant to ensure any males are removed before they can pollinate their female counterparts.
Growers can avoid spending weeks nurturing plants with only a 50% chance of expressing as female and maximize the space and plant count in their gardens by using feminized seeds from suppliers like Kannabia. These specially-treated seeds increase the probability of producing a female plant to 99%.
How Are Cannabis Seeds Feminized?

There are a few techniques that can produce reliably feminized seeds. One classic method is stressing out a healthy female plant by interrupting its light cycle during flowering. While that works to an extent, the more common and controlled method is to spray down female plants with a collodial silver or silver thiosulphate solution. This method makes it possible to control the sex of a plant without any genetic tinkering or modification.
Both substances are a blend of water and fine silver particles, and they work in largely the same fashion. The silver solution impedes the production of ethylene, a hormone involved in flowering. The result is a female plant, but one that produces male flowers with pollen sacs. Since those pollen sacs develop on a plant with only female genetics, female genetics are all they carry. When those flowers pollinate another female plant (one untreated by silver solutions), the resulting seeds are nearly certain to be female.
Treating plants with a silver thiosulphate solution results in seeds that will produce feminized plants nearly 100% of the time, and Kannabia’s breeders have found this method to be the most effective way to maintain the stability of the seeds and future feminized plants.
Feminized Varieties to Try in Your Garden

Growing cannabis in your home is legal in an increasing number of states and provinces throughout the United States and Canada. To make starting a home garden easy, growers can start with feminized seeds for many popular strains from providers like Kannabia.
“In our search to find new genetics, Kannabia paired us with their feminized Russian Doll seeds,” say growers at Canada’s BlueSky Organics. “Every seed germinated, and now that we are in the late vegetative stage, these plants have an extremely hardy trunk preparing themselves for some massive buds.”

Feminized Cannabis Seeds
Feminized Seeds – If you want to buy quality feminized cannabis seeds, you must understand precisely what it is you’re buying. Feminized cannabis seeds are not just premium seeds with a higher price tag. They are marijuana seeds carefully bred to produce only female cannabis plants — no males, no seeds.
To be clear, female cannabis plants are the only ones that develop flowers and thus the only ones to produce a useful amount of cannabinoids like THC and CBD. Though males produce no flowers or cannabinoids, they do produce pollen and a powerful desire to pass that pollen to some nearby ladies. And they’re good at it, too! A single male can pollinate hundreds of female cannabis plants within miles.
Female Only Plants
By growing female-only cannabis seeds, you avoid the risk of male plants pollinating nearby females. This is important for a few reasons. First is the convenience and bag appeal of a seedless sack of weed. There’s nothing better than opening up a jar of some fine sensimilla, or seedless cannabis flower, and there’s no better feeling than knowing that you grew that premium bud yourself from a small seed.
Secondly (and perhaps most importantly), is the fact that seedless cannabis produces higher cannabinoid levels compared to seedy weed. Essentially, the moment a female cannabis plant is pollinated, her energy averts from producing cannabinoid-rich flowers toward producing the healthiest offspring possible. Indeed, Mary Jane is a strong female, and if pollinated, she will sacrifice cannabinoid production for the sake of her kids.
While we certainly appreciate Mary Jane’s dedication to her lineage, sometimes it’s best to avoid the risk of male pollination all-together. To do this, we recommend buying feminized cannabis seeds.
What Are Feminized Cannabis Seeds?
As mentioned, feminized cannabis seeds are simply seeds specially bred to produce only female flowers. The most common method for producing feminized marijuana seeds is to stress a female into producing her own pollen sacks as a means of protecting her genetic line. Basically, by stressing a female cannabis plant, she briefly assumes she’s done-for and will pollinate herself or other nearby females so her genetic line will not die. Score one for evolution!
After carefully stressing a female into pollination, breeders can confidently sell the resulting seeds as “female cannabis seeds,” knowing full-well that no males will be in the mix.
Pollen from male plants contains both X and Y chromosomes. As such, seeds produced from male pollen will produce either female plants (which contain only XX chromosomes) or male plants (which contain both X and Y chromosomes). By removing the male from the pollination process, there is no Y (male) chromosome to pass on to the next generation. Hence, all seeds produced from a pollinated female plant will only contain female genetics. Unless the next generation is also stressed, they should all produce seedless cannabis flower.
Should You Buy Feminized Seeds?
At Greenpoint Seeds, our primary focus is on regular cannabis seeds. These allow both growers and breeders the opportunity to experiment with different strains at a relatively low price. However, we also offer many feminized seeds to make the cultivation process easier, albeit at a slightly higher cost. The increased price point is solely due to the additional feminizing step these seeds endure; both our regular marijuana seeds and our feminized seeds produce dank buds with high cannabinoid levels.
When choosing between regular and feminized cannabis seeds, there are a few things to consider. For example, will you have the time and the capacity to pre-sex your cannabis plants before transitioning into the flowering stage? This process is easy enough for small grows, but large operations often have difficulty pulling all males before it’s too late. The size of your grow and the time you’re willing to invest are significant factors when choosing the best cannabis seeds for your needs.
Additionally, consider your permissible plant-count. Many legal states only allow a certain number of plants per adult and household, and you may not want to fill up your quota with plants that may or may not make it. In this case, we recommend feminized cannabis seeds.
Finally, do you plan to breed your plants? Cannabis strain breeding is an advantageous hobby but usually requires the use of both male and female plants. If breeding your plants is on the horizon, regular cannabis seeds may be a better option for you.
