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.
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.
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.
How Are Cannabis Seeds Feminized?
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%.
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.
If you have more questions about strains or seeds, keep digging through Leafly’s resources. And to learn more about the variety of feminized seeds available to you, visit Kannabia’s website to see its full line of feminized genetics, including strains like Diesel Glue and the award-winning Mataro Blue.
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.
It should be everyone’s right to grow male and females of what they’re buying and back-cross and pheno-hunt and pheno-cross as much as they like, this is far more valuable than the luxury of getting 5 seeds that are all known to be females but missing part of their genetic code.

I’ve been told that the most stable cross would be found from parents grown from regular seeds. Your article seems to portray that as a myth.

In fact, this forms the basic principle of how feminized seeds were developed. But mitigating these intersexual tendencies is also the objective of developing stable feminized seeds. Sensi Seeds has been perfecting the process of feminized breeding for years now, all so that home growers can minimize the chance of intersexuality in their plants.
I hope this clears up any confusion as to the intention of this article.

However, over the years, the seeds and the methods used for their production have reached very high levels, becoming a real art. The quality of the feminized marijuana seeds that you find on the market today is extremely high and the chances of a hermaphrodite plant developing are almost zero. When feminized seeds were introduced to the European market in 1998, a real revolution began which inevitably led to a lack of interest in regular seeds. Today, over 95% of the European cannabis seed market is occupied by feminized seeds. In the United States, however, regular seeds continue to have an important market, still managing to cover a large part of the sector.
This is what feminized seeds look like
In the current cannabis seed market, it is possible to buy both regular and feminized seeds. But, what’s the difference? Beginners could purchase seeds without understanding the real difference. Further, we explain the main characteristics of each of them and how they can influence cultivation. This is done in order to evaluate which are the most suitable cannabis plants for your needs. Regular seeds are completely pure and natural and produce both female and male cannabis plants. Feminized seeds are seeds obtained from Cannabis plants treated with special agronomic techniques. In this case, the plants produced from these seeds will express only the female sex. The first seed company to introduce feminized seeds to the market was “Dutch Passion” in 1998.
Feminized seeds and the methods
Both of these seeds have their own qualities that make them unique.
For most growers, feminized seeds are the ideal choice when buying a variety of cannabis: they produce excellent quality grass without the risk of running into some male plants. When a professional cannabis grower wants to produce his own seeds and create his own hybrids he needs to work with plants that show both male and female sex. This is necessary in order to pollinate female flowers with male pollen, thus obtaining new genetic crosses and new seeds. This is one of the main reasons why regular seeds continue to be grown.
Thus a real revolution in the cultivation of cannabis seeds began. Today, we find several seed companies on the market that offer a wide range of feminized seeds in their catalogs. And, in some cases, there are companies that sell exclusively this type of product. The reason for this commercial strategy is quite obvious: most cannabis growers are not interested in hybridization and their only goal is to produce large quantities of top quality marijuana. This means that the ultimate goal is to grow only female cannabis plants. Buying feminized cannabis seeds avoids wasting time and being overwhelmed by frustration (there is nothing worse than growing numerous cannabis plants for several weeks and then discovering that half of them are male when the target initial was to get only female plants). When introduced to the market, the feminized seeds initially showed a rather poor quality, receiving heavy criticism from the public (given the high percentage of hermaphrodite Cannabis plants that developed from these seeds).
In a sense, one could say that this growing market interest in feminized seeds could become very dangerous for cannabis communities, turning cannabis growers away from experimentation and dissuading newcomers to create new and interesting varieties. In fact, if we consider a seed company specializing exclusively in the sale of feminized seeds, a grower will never have the opportunity to exploit those particular genetics to create new hybrids. Fortunately, there are still some companies out there that are interested in maintaining this market, where normal growers are allowed to experiment with hybridizing cannabis through regular seeds. Most recommend the use of the seeds, especially for beginner growers.
