Feminized Seeds | Everything you Want to Know About
Feminized seeds have completely changed history, and nothing will ever be the same again. In this monograph on feminized marijuana seeds we take a closer look at their creation, history, chemistry, advantages, best strains and many other aspects in a complete guide, come join us!
What does the term feminized mean?
The term “feminised” in the context of cannabis refers to seeds that have been modified or treated to produce almost exclusively female plants. This process is carried out to maximise the production of cannabinoid-rich flowers, which are produced by female cannabis plants. Male plants, on the other hand, produce pollen and not flowers, and can reduce flower production if they pollinate female plants.
Feminised seeds are the result of a process that involves manipulating the life cycle of the cannabis plant to produce seeds that will produce female plants. This process can involve several techniques, including spraying with colloidal silver, the use of silver thiosulphate, and self-pollination. The end result is a seed that has a very high probability of producing a female plant.
Origin of the feminized seeds
Feminized seeds are a relatively recent development in the history of cannabis cultivation. Although cannabis has been cultivated by humans for thousands of years, the idea of producing seeds that will produce almost exclusively female plants is a concept that has only gained popularity in recent decades.
The origin of feminised seeds can be traced back to the 1970s and 1980s, when cannabis breeders began experimenting with the idea of manipulating the sex of cannabis plants. These early experiments often involved techniques such as colloidal silver spraying or self-pollination, and while they were usually successful, they laid the groundwork for the development of feminisation techniques used today.
Chemistry of these seeds
Feminised cannabis seeds are genetically identical to regular cannabis seeds in terms of their basic chemical makeup. Both contain the ability to generate the same types of cannabinoids and terpenes, which are the chemical compounds responsible for the psychoactive and therapeutic effects of cannabis. However, feminized seeds are more likely to produce female plants, which tend to produce more cannabinoids and terpenes than male plants.
In addition, feminised seeds can be influenced by several factors, including the growing environment and the genotype of the mother plant. These factors can affect the concentration and ratio of cannabinoids and terpenes in the resulting plant, which in turn can affect the effects and therapeutic benefits of cannabis.
Who created the first feminised seed
The creation of the first feminised seed is a matter of debate, as many breeders and seed companies have claimed this honour. However, it is widely accepted that the popularisation of feminised seeds in the cannabis industry can be attributed to the Dutch seed company Dutch Passion in the 1990s.
Dutch Passion was one of the first companies to commercialise feminised seeds on a large scale, and their feminisation techniques, which include the use of colloidal silver and silver thiosulphate, have since been adopted and refined by many other seed producers. While the creation of the first feminised seed may be a matter of debate, there is no doubt that Dutch Passion played a crucial role in the popularisation of these seeds.
Differences between feminised, regular and autoflowering strains
Cannabis seeds can be classified into three main categories: regular, feminised and autoflowering. Regular seeds will produce a mix of male and female plants, and are the preferred choice for breeders wishing to produce new strains of cannabis. Feminized seeds, as we have discussed, have been modified to produce almost exclusively female plants, and are the preferred choice for growers who wish to increase their flower production.
Autoflowering seeds, on the other hand, are a unique category of cannabis seeds that flower automatically after a certain period of time, regardless of the light cycle. These seeds are the result of breeding regular or feminized cannabis strains with cannabis ruderalis strains, which are known for their ability to flower automatically. Autoflowering seeds are a popular choice for growers who want a quick and easy harvest, as they do not require the light cycle change that is needed to induce flowering in regular and feminised strains.
A female and a feminised seed is the same?
Although the terms “female seed” and “feminised seed” are often used interchangeably, there is an important difference between the two. A female seed is a seed that has been produced by a female plant and has a 50% chance of producing a female plant. A feminised seed, on the other hand, is a seed that has been modified or treated to produce almost exclusively female plants.
The main advantage of feminised seeds is that they maximise the production of cannabinoid-rich flowers, which are produced by female cannabis plants. Male plants, on the other hand, produce pollen and not flowers, and can reduce flower production if they pollinate female plants. Feminized seeds are therefore the preferred choice for growers.
There are several techniques for feminising cannabis seeds, each with its own advantages and disadvantages. Some of the most common techniques include spraying with colloidal silver, the use of silver thiosulphate, self-pollination, and rodelisation.
Colloidal Silver Spraying (CSR)
Colloidal silver spraying (CSR) is one of the most common techniques for feminizing cannabis seeds. This method involves spraying a female plant with a colloidal silver solution during its flowering period. Colloidal silver inhibits the production of ethylene, a plant hormone that is crucial for the formation of female flowers. This induces the plant to produce male flowers, which will produce pollen containing only X chromosomes. When this pollen is used to pollinate another female plant, the resulting seeds will be feminised.
RSP is an effective and relatively simple method of feminizing cannabis seeds, but requires careful handling. Colloidal silver is a heavy metal that can be toxic to humans if ingested or absorbed through the skin, so it is important to take safety precautions when using this technique.
Silver thiosulphate (STS) is another technique commonly used to feminize cannabis seeds. Like colloidal silver, STS inhibits ethylene production, which induces female plants to produce male flowers. However, STS is generally considered more effective than colloidal silver for feminising cannabis seeds, and is the technique of choice for many commercial growers.
Using STS to feminise cannabis seeds involves spraying a female plant with an STS solution during its flowering period. The resulting male flowers will produce pollen containing only X chromosomes, and when this pollen is used to pollinate another female plant, the resulting seeds will be feminized. As with colloidal silver, it is important to take safety precautions when using STS, as it can be toxic to humans if ingested or absorbed through the skin.
Self-pollination or Spraying with Gibberellic Acid
Self-pollination is another technique that can be used to feminise cannabis seeds. This method involves inducing a female plant to produce pollen, which is then used to pollinate the same or another female plant. Self-pollination can be induced in a number of ways, including environmental stress, genetic manipulation, and spraying with gibberellic acid.
Gibberellic acid is a plant hormone commonly used in agriculture to promote seed growth and germination. When sprayed on a female cannabis plant during its flowering period, it can induce the plant to produce male flowers, which in turn will produce pollen containing only X chromosomes. When this pollen is used to pollinate the same plant or another female plant, the resulting seeds will be feminised.
Rodelling is an all-natural method of feminising cannabis seeds. This method involves allowing a female cannabis plant to go through its normal flowering period without being pollinated. In response to this lack of pollination, the plant may begin to produce male flowers in an attempt to self-pollinate. These male flowers will produce pollen containing only X chromosomes, and when this pollen is used to pollinate the same plant or another female plant, the resulting seeds will be feminised.
Although rhodellisation is an all-natural method of feminising cannabis seeds, it is not as effective as other methods such as spraying with colloidal silver or using silver thiosulphate. However, it is a popular choice for growers who prefer to avoid the use of chemicals in their cannabis cultivation.
Benefits of feminized seeds
Feminised seeds offer several benefits for cannabis growers. Firstly, they maximise the production of cannabinoid-rich flowers, which are produced by female cannabis plants. Male plants, on the other hand, produce pollen and not flowers, and can reduce flower production if they pollinate female plants.
Feminized seeds also eliminate the need to sex cannabis plants, which can be a laborious and time-consuming process. With feminised seeds, growers can be sure that almost all of the plants they grow will be female, allowing them to plan their crop more accurately and efficiently.
Disadvantages of this type of seeds
Apart from the benefits, they also have some drawbacks. Firstly, feminized seeds are usually more expensive than regular seeds, due to the additional feminisation process. Also, feminized seeds are not suitable for breeders who want to produce new strains of cannabis, as they do not produce male plants that are needed for pollination.
Although feminised seeds have a high probability of producing female plants, it is not a guarantee. Environmental and genetic factors can influence the sex of cannabis plants, and it is possible for a feminized seed to produce a male or hermaphrodite plant. Therefore, growers using feminized seeds should continue to monitor the sex of their plants during the flowering period.
Recent innovations in feminized seeds
Recent innovations in feminised seed production have led to the creation of high-quality feminised seeds that produce female plants with unprecedented consistency and reliability. These innovations include improvements in feminisation techniques, such as the use of colloidal silver and silver thiosulphate, as well as advances in cannabis genetics that have allowed breeders to produce cannabis strains with unique cannabinoid and terpene profiles.
In addition, the legalisation of cannabis in many places has led to increased research and development in the cannabis industry, resulting in the creation of new cannabis strains and improved cultivation techniques. These innovations have made feminised seeds an increasingly popular choice for cannabis growers, both amateur and commercial.
