what are feminized cannabis seeds

Feminized seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized seeds mean that they are treated to make them female (hence the name feminized) so that all the seeds can be used to get flowers. Breeders usually sell feminized seeds for their strains because they are easier to grow and are too unstable to reproduce, although some people use plants from feminized seeds to get cuttings, it is advisable that they use females from Regular seeds. It is recommendable to start growing with Feminized seeds, this will mean that the final plant won’t have any undesirable surprises like seeds reducing potency since there are no male plants.

When you wonder what does feminised seeds mean, the key is in the sex!

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.

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.

Feminized seeds and the methods

This is what feminized seeds look like

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).

Both of these seeds have their own qualities that make them unique.

“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.”

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.

How Are Cannabis Seeds Feminized?

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.

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.

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 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.
