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.

“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.”

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.
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.

Most cannabis seeds contain a mix of indica and sativa genetics (technically making them hybrids) and display characteristics of both as a result. The datasheet will tell you the exact ratio of genetics (for example: 50% sativa, 50% indica).

How To Grow Feminized Cannabis Seeds
Plants will need different ratios of these nutrients during the vegetative and flowering phases, alongside adjustments in micronutrients like calcium, iron, magnesium, copper, and several others.
Pre-made cannabis fertilisers offer an easy solution with specific formulas for each stage of growth. RQS Easy Boost supplies all of the foundational nutrients needed throughout the growing cycle. Easy Grow adds additional vegetative nutrients, and Easy Bloom covers all of the necessary bases for optimal flowering.
To avoid root rot and harming plants, ensure the soil is dry before watering. You can quickly check the dryness by inserting your finger knuckle-deep into the substrate. If the soil still feels moist, wait another day before checking again. If in doubt, water well, but not too often!
Today. Feminized seeds are bred in a way that enables them to develop and flower as female plants only. Their breeding process eliminates virtually all male chromosomes; the probability of female plants growing is 99.9%.
Wild cannabis plants are typically hermaphrodites, meaning they carry the physical traits of both sexes. This is done as an emergency response to the lack of either sex in a certain crop and also allows for self-pollination. This dioecious trait has been bred-out of most contemporary, commercialized plants, in order to manipulate the cultivation process and save time by removing the need to sex plants. Good quality feminized strains on the commercial market are all but resistant to becoming hermaphrodites, particularly if grown in proper conditions.
Before feminized seeds were introduced to the market, regular seeds were the norm. These were typically made up of 50% male and 50% female seeds. This was often a source of frustration for growers who were forced to double the number of seedlings in order to ensure a satisfactory number of female plants for future cultivation.
Because male plants can fertilise many females, the popularity of feminized seeds continues to significantly aid the future preservation of cannabis strains for generations to come.
The creation and evolution of Feminized cannabis seeds have been one of the defining moments in the expansion of the cannabis market over the last few decades.

The creation of feminized cannabis seeds meant that the inconvenience of male plants, particularly their size, was no longer a concern.
