How Feminized Cannabis Seeds are Made
Feminized cannabis seeds are a type of cannabis seed that has been bred to produce female plants. This means that the plants will not produce any male flowers or pollen. They are a great option for those who want to grow their own cannabis but don’t want to deal with the hassle of crossing over from regular marijuana plants.
Difference between male and female marijuana plants
The main difference between male and female cannabis plants is that male cannabis plants do not yield buds, whereas female cannabis plants do. This means female plants produce usable cannabis (buds), and male plants do not. There are many other obvious as well as subtler differences between male and female cannabis plants that can affect a cultivator’s crop.
The main advantage of feminized seeds is that they will not produce any male flowers. This means that the female flowers will develop and produce the best quality buds. With feminized seeds, you will not have any unwanted male plants in your garden, which helps cut down on wastage and speeds up the flowering process.
If you have a large number of female plants growing, then it is relatively easy to identify which ones produce the best quality buds, so you can harvest all the buds off these plants to use in other products such as hash or oils.
How to feminize cannabis seeds
There are two main ways to make feminized pollen:
A cannabis seed typically has a 50/50 probability of developing either a male or a female plant. The plant’s DNA has a biological program that is designed to increase its chances of procreation and, of course, overall survival. The X and Y chromosomes, like in humans, determine gender.
Ninety-nine percent of the time, a plant will produce a male if it has one of each chromosome. A cannabis plant has a 99.9% chance of being female if it has two X chromosomes. During the flowering stage, plants are treated with colloidal silver to produce feminized seeds. Using this method, female plants are converted into hermaphrodites (a plant that is both male and female). They are compelled to generate female pollen-filled seed sacs instead of buds as a result.
In rare instances, a female cannabis plant may begin producing male pollen sacs or bananas spontaneously, which the plant can use to self-pollinate. When a plant is stressed or not harvested on time, buds begin to wither and die. In essence, the plant is exerting every effort to produce seeds and protect the future generation. These seeds are mainly female because of this “natural” process. The issue with this approach is that you’re choosing plants that develop both male and female sex organs independently, without chemical inducement. This implies that the seeds that arise are far more likely to become hermie under normal circumstances. If you don’t want seedy buds every time you harvest, that’s an issue. It is strongly advised that you avoid feminizing seeds in this manner. Additionally, it’s a good idea to discard any seeds that are the product of natural herming (such as seeds you discover in your buds while not growing any male plants).
Growing marijuana from feminized seeds
Growing marijuana from feminized seeds follows the same procedures as growing it from ordinary seeds. Keep these points in mind if you want to attempt growing cannabis and are aware of your area’s rules and legislation.
Before you plant the first seed, you must answer the following questions:
- Do you like cultivating marijuana inside, in a greenhouse, or the open air?
- What strain(s) are you planning to grow?
- Will it be photoperiod or autoflowering?
- Are you planning to cultivate a cannabis plant from seed or a clone?
- Which growing media are you going to employ? An aeroponic system, regular soil, or a hydroponic solution?
Answering these questions will raise further queries.
- Will you utilize natural or artificial light if you’re growing indoors?
- If you switch to hydroponics, will you also utilize a growth medium like Rockwool or Hydroton?
While it is possible to purchase a clone, plant it in soil, and hope for the best, it is recommended to approach marijuana cultivation cautiously and conduct an extensive study first. If that’s not your thing, you may treat marijuana like a houseplant and try a straightforward indoor grow with natural light. If you begin with one or two plants on a sunny windowsill and end up with a good harvest, you may upgrade to a more complex arrangement or stick with the original one.
It all depends on your particular preferences and how much work you want to put into it, much like most things in the cannabis industry. Regardless of your chosen method, you will need to buy cannabis seeds. You can check out the Herbies headshop for the best selection of feminized marijuana seeds.
How to Feminize Seeds
The cannabis industry has evolved more in the last 15 years than it has in the last century. Society has also evolved, allowing cannabis and the idea of weed to slowly make its way into pop culture, with more and more strains available as well as accessories for smoking or consuming cannabis. Nowadays, pretty much anyone can grow cannabis in their own house with all of the necessary equipment to make their own strains. Years ago only a select few had access to such equipment. Today we’re going to show you how to feminize seeds. You won’t need many items to do so, and the ones you do need are easy enough to get.
Like most living creatures, cannabis plants need a male and a female specimen to reproduce; the male pollinates the female plant which causes seeds to grow. The resulting seeds have genes from both the mother and father plants, so it has a 50% possibility of being female or male. This is why you need to find a way to get your seeds by using just female plants, completely getting rid of male genes, which only leaves the possibility for female seeds.
How to Feminize Seeds | Tutorial
Many growers know that if you stress out cannabis plants, they can easily become hermaphoridtes (a plant with both male and female sex organs) which end up creating male flowers that create pollen which then “impregnates” the plant and others around it. The issue with stress-caused hermaphrodite plants is that most of the resulting seeds tend to be hermaphrodites too, so it’s not the best method to use and it also stresses your plants out quite a lot.
In order to turn a female plant male without stressing it out, all you need is some Silver Thiosulfate, also known as STS. If you apply STS to female plants it will modify their ethylene levels, which is the hormone in charge of determining the sex of certain plants. This causes female plants to change sex and turn into males without the disadvantage of male genes.
Making your own STS only takes about 15 to 20 minutes and you’ll need two ingredients: Sodium Thiosulphate and Silver Nitrate, both of which can easily be found in any pharmacy and on our webstore. Sodium Thiosulfate is a neutral chemical salt that’s used to reduce side-effects in some cancer treatments and can easily be bought without a prescription.
You can acquire silver nitrate on our webstore, although some people prefer to extract it from other products that contain it, such as Argenpal, a product used to get rid of warts – each one of these little contains a very small amount of Silver Nitrate, so it’s probably better just to buy it directly without the need to spend more money or spend forever trying to extract the Silver Nitrate from the product itself. We stock Panreac Silver Nitrate, which may be a bit more expensive but you’re guaranteed the best quality, and it saves quite a lot of time.
How to Feminize Seeds | Making STS
You’ll need protective material such as gloves, safety glasses and a face mask; STS can be quite toxic when inhaled and it can leave large burns on the skin. Make sure you don’t use any metallic objects when making STS – everything should be plastic, as metal can alter the composition and reduce efficiency.
Do not use metal instruments or tools in this process. The first thing you’ll need to do is grab a plastic cup and pour in 20ml of distilled water. Next, depending on your chosen method, get either 7 Argenpal sticks or 0.35g silver nitrate. If working with Argenplal, dilute the tips delicately in the water (the tip is where the silver nitrate is). Grab another plastic cup and add 30ml distilled water and 1.3g of sodium thiosulfate, mixing it slowly until it’s fully dissolved. Then, mix the contents of both glasses and mix slowly again – make sure to use a plastic spoon, no metal.
The result is 50ml of pure Silver Thiosulfate, much too potent to use on your plants, so you’ll need to water it down a bit. Add your Silver Thiosulfate to 400ml of distilled water, so you’ll have around 450ml of STS. Make sure to shake quite a lot until it’s completely mixed. It’s still much too concentrated to apply straight onto your plants; take 100ml of the mixture you just made and add it to 400ml mor of distilled water. You now have 500ml of a usable STS mixture that’s ready to be used on your plants.
For maximum efficiency you’ll need to use it the same day you make it. If stored in a dark, cool space it can last up to 15 days but each day it’ll be a bit less potent. If you have it for over a week and haven’t used it we recommend making another batch if you want the best possible results.
How to Feminize Seeds | How to use STS
STS is used by spraying it on your plants leaves, making sure that it’s entirely covered and dripping. We recommend taking the plant away from your growing area before beginning the process, or the mixture might end up getting on your other plants too. You’ll need to begin applying it 4 or 5 days after flipping the lights, right before your lights go off. This allows you to spray the plant without worrying about the light burning your plants. After 10 days, you need to respray your plants, using the same process, covering the plant in the mixture and letting it soak in in the dark.
The sprayed plant will begin growing male flowers with pollen with can then be used to pollinate whichever plant you want, causing seeds to appear that have absolutely no male genes in them. You can use the pollinated plant in order to make extracts from its resin; the amount of seeds it’ll produce will render it pretty much useless in as far as smokeable flowers. The plant that you’ve applied the STS to will need to be thrown away, as it’s much too toxic to do anything with and if you consume any of it, even its resin, you could run in to some health issues.
When should you polinate your plants?
In order to efficiently pollinate select plants, we recommend having two completely separate grow rooms or areas to work in. One should be for the plants that you’re planning on switching to male in order to obtain female polen; the other should be specifically for the plants that you plan on pollinating once you’ve reverted the other ones.
When using the pollen that you’ve collected from your reverted plants, you need to make sure that the plant that you plan on using it on is fully ready for it; this can depend on the strain you’re growing. The right time to begin applying feminized pollen is actually right when your plants begin to flow real flowers.
You generally want to use the pollen as fresh as possible on a plant that is fully ready to take it on, or else it simply might not work – it’s kind of like people, in that sense. Certain things need to be just right. To harvest large amounts of high quality seeds, you’re probably better off doing a few tests in order to find out when the right moment is. You can do this by testing it out on the same strain before going big.
How to Feminize Seeds | Make your own strains
When making your own seeds you can combine your favorite strains, resulting in a plant that you’ve created yourself that is 100% feminized. When you combine two strains, you’ll get various phenotypes with varying qualities and structures. It’s important that you use regular seeds to do this, as feminized ones are much too weak and might have issues such as stress and end up becoming hermaphrodites.
In order to stabilize the genes in your resulting plants, you’ll need to select the phenotypes you like the most, meaning that you’ll need to grow quite a lot of the seeds that you get from your feminized plant. Then, take a clone from each plant and set them to flower in order to study their characteristics. Once you’re done, you’ll need to pick two mother plants, revert them and cross them with each other to get a more balanced version. This process is repeated as many times as necessary in order to create a balanced strain that has the characteristics you’re looking for.
Feminizing cannabis seeds is quite the process. You need to be able to keep perfect track and control of the timing when it comes to flowering and pollen yield if you want the best possible results. Take your time, do a few controlled tests and then you can start making large amounts of your own seeds.
Feminized cannabis seeds
Feminized cannabis seeds first appeared in the 1990’s, they were invented by Dutch Passion and feminized cannabis seeds now account for 95%+ of all cannabis seeds sold.
Regular cannabis seeds produce male and female plants in roughly equal numbers. But today regular cannabis seeds account for under 3% of Dutch Passion seed sales, even though our 15 varieties is one of the most complete collections of regular cannabis seeds still available. Most home growers simply do not like to use their time, space and electricity growing male cannabis plants. Most home growers prefer to grow a small number of high quality female plants, and the best way to do that is from cuttings (clones) or from feminized cannabis seeds , which are usually bought online or from the local seed shop.
How were feminized cannabis seeds created?
Back in the 1990’s Dutch Passion’s founder, Henk van Dalen , was growing some cannabis plants from regular seeds, they were the only type of cannabis seed available at the time. Cannabis growers had dreamed of feminized cannabis seeds, but it was generally accepted that it was not possible for cannabis. One day Henk noticed something unusual when studying some female plants which had been left to flower for several weeks longer than usual. It was one of those experiments just to see what happened if a female was left to bloom for much longer than anyone would normally think about. It was an experiment that would change cannabis growing forever, because he noticed the female plants eventually produced male flowers. Henk collected the pollen and used it to pollinate some other female plants and a few weeks later he collected the seeds which had formed. Again, it was one of those experiments done ‘just to see’ what happened.
The seeds were planted, and to everyones astonishment every seed produced a female plant. There was huge eagerness to try to understand it, and perhaps a chance to repeat the experiment and see if this discovery could be put to a practical use. So more female plants were grown from regular seed, and sure enough several weeks after the normal harvest date, the females began to produce male flowers. The pollen was carefully collected, Henk called this ‘female pollen’ because the seeds created from it only gave rise to female plants. This larger, second experiment confirmed the initial findings. Feminized cannabis seeds had been created at Dutch Passion, though at first not everyone believed it.
The process of collecting ‘female pollen’ from over-ripe female cannabis plants was not suitable for mass-production of seeds. Today each seed company has their own preferred chemical way of creating ‘female’ pollen to use in the creation of feminized seeds.
Today, feminized cannabis seeds are vital to growers of all kinds. Feminized autoflowering cannabis seeds are becoming almost as popular as photoperiod seeds, they are an easy and convenient way to grow cannabis both indoors and outdoors. Many first time cannabis growers choose feminized auto seeds because they are so easy and flexible to grow.
Feminized CBD-rich cannabis seeds are popular with medical growers. Many outdoor growers also rely on feminized seeds, without them they would risk male plants pollinating the entire crop.
Regular seeds are popular with some old-school growers and small scale seed banks. Dutch Passion’s regular seed sales are so low that we regard it as a service rather than a viable business. For most growers, feminized seeds are the preferred way to grow your own cannabis.
