Increase your chances of obtaining feminized seeds before harvest
When traditional methods of fertilization are used to grow your marijuana plants, you have less control over the sex of future marijuana plants. Therefore, there are a lot of marijuana growers who take extra steps to make the appearance of female plants more likely. Only females produce the coveted buds and components needed for medicinal or recreational purposes. So how do you feminize your cannabis seeds before harvest? How to get only feminized seeds on your plant?

Feminized cannabis seeds
Generally speaking, there is no way that you can tell the difference between male and female marijuana seeds in the initial stages of planting. Plus, you can't change the gender either. The concept of having feminized marijuana seeds is to maximize the female seeds that will be part of your marijuana grow.

Why would you want female plants? Well, they are known to have a higher level of THC content. Male plants have a reduced THC content and it is for this reason that female plants have priority over male plants. Along with the feminization of cannabis seeds, there are several pollination techniques that the marijuana grower can use for a favorable result.
Buy Feminized Cannabis Seeds

Female cannabis seeds are sold by various companies. So you won't have to wait long to get the right one for you. By doing so, you will be sure that your result will be a female marijuana plant with more THC. Be careful when buying marijuana seeds online. Make sure it is a reputable company known to sell and deliver the right female marijuana seeds.
Alternative methods
If you want to try the feminization of marijuana seeds yourself, then there are some methods that you can use namely:
- Colloidal silver
- Silver Thiosulfate Solution
- Rodelization
Each of these methods should succeed, if used appropriately to produce marijuana plants. Let's take a quick look at each method briefly.
The silver thiosulfate method
Silver thiosulfate solution, also known as STS, is one of the most common methods of female marijuana seed production. It is very effective in enabling female marijuana seeds to be available to marijuana growers. Using this method feminizes the seeds in the best possible way, making it more available in the market for growers.

The solution consists of a combined silver nitrate and sodium thiosulfate. The result of the solution is a hormonal stress response found in the marijuana plant. As a result, a gender change is triggered. You can do it all yourself, but marijuana plants should be chosen wisely. You should only take female plants of a single strain of cannabis which is almost mature. Then you separate the plant and spray it with the STS and let it dry, making sure it sits next to the other plants.
The colloidal silver method

With colloidal method or pure silver, you also need distilled water. Use a spray bottle to apply this mixture to your female marijuana plants, but you should do this when the plants are in bloom. Pollen has female genetics that allow marijuana seeds to produce female plants.

Leave this for seven hours or more - The longer it takes, the better it is because it increases the concentration of colloidal silver. That being said, leaving it too long will eventually make the particles too big. At this point, you can spray your plants and carry out the feminization process. Spray them daily until they reach the flowering period. It should take less than two weeks although the timing may vary.
The "rodelization" method
The "rodelization" method calls for the reaction of female plants when they are stressed. The pollen sacs will grow when the plants are stressed and unfertilized. Due to the fact that the resulting marijuana seeds are derived exclusively from female genetics, it is likely to be female seeds and not male seeds.

The goal of the rodelization technique is to keep your female plants in their flowering phase longer than normal. Plants should have a normal “panic” response and go into a “self-pollination” mode. As soon as the pollen sacs start to emerge, you can harvest the pollen normally.

The main disadvantage of this method is the unreliability - even if everything works well, the seeds might not be feminized. Because of this risk, you must think carefully about whether or not this method is for you. Some strains will also work better than others with this method.
