How to Feminize Marijuana Seeds

how to feminize marijuana seeds

Growing marijuana feminized seeds make things easier for you. You don’t spend some time separating male plants from the female ones. Since you will only deal with feminized plants, you can also save some space in your garden.

You may avail feminized seeds from a reputable bank seed so you can get started. But to make sure the quality, you can learn how to feminize marijuana seeds by yourself. 

Some feminized seeds can be hermaphrodites, which you don’t want. So making feminized marijuana seeds on your own will save you from any undesirable instances.

Introduction to Feminizing Marijuana Seeds

Some growers would stress out the marijuana plants, and it would result in hermaphrodites, which have both male and female organs. Hermaphrodites can impregnate the plants and end up with male plants. So stressing out the plant won’t fulfill your wish to have stable feminized seeds.

It’s best to use regular seeds to feminize as some feminized seeds are prone to stress. To avoid the possibility of this certain chemicals will help you with the process.

Feminized seeds would create a plant that produces buds with such potency. But when making the seeds, you should think of a breeding program to stabilize the result of the process. Quality feminized seeds mean that there’s prevention to the development of hermaphrodites.

How to Feminize Marijuana Seeds With the Use of Chemicals

Colloidal Silver

It is a substance that is made from releasing minute particles of silver into the water. It’s impossible to be detected by the naked eyes as it measures 100 nanometers. 

You can buy bottled colloidal silver online. You can do it if you only need to use it a few times. 

Steps on Making Feminized Seeds with Colloidal Silver

Step 1

Spraying the female plant’s bud sites should be done every day on the first 3 to 4 weeks of the flowering period. You have to see to it that the pollen sacs form, and they can split open.

When you switch to a 12/12 light schedule as you’ve begun with flowering time, the bud sites should be covered with colloidal silver. Then male pollen sacs come out when the flowers have developed.

The parts that are not treated with colloidal silver will remain female. But when they had contact once with the substance, it’s unsafe to smoke. 

Step 2

You would know that pollen sacs are ready to harvest when they appear swollen like a balloon. Don’t do the harvest if you don’t see this state. You have to be consistent in spraying it so you won’t find empty pollen sacs in the end.

Another sign that would tell you that the pollen sacs are ready is when cracking happens on the leaf section that acts as a protection for the pollen. You can start collecting the pollen.

Dry them for a week after collecting. When they’re dried, you can place them in a bag and shake so you can collect the pollen with ease.

Step 3

Once you’re ready with your pollen, you can pollinate the female plant. It should be on the 2nd or 3rd week of the flowering period. 

You may pollinate the same plants, but the timing is not right. It’s not effective to do the process when the plant is in the late part of the flowering stage. It can cause lower seed production.

A different female plant that started budding later than the first plant. It doesn’t only increase the production of seeds, but it also gives enough time for the female plant to complete maturity. It can create genetic diversity compared to using just a single plant.

Step 4

The calyxes of the female plant’s buds will become fat and swollen. It would take six weeks after the pollination. They would burst out, and you can collect your feminized seeds.

STS or Silver Thiosulfate

It is a chemical mixture that can induce the formation of feminized pollen. It’s commonly used for creating feminized seeds as it is proven to be effective. 

Female plants rely on ethylene production, and without it, male plants that abound with feminized pollen will surface. STS comes in this scenario as it inhibits ethylene production. 

How to Make STS

If you have no idea of making the mix, you might think that it can be complicated. It’s like making a juice drink from a powdered mix.

There are two stock solutions for this. You can put them as A and B. A is composed of distilled water and silver nitrate while B has distilled water to but with sodium thiosulfate.

You would need a light-proof bottle for storing this solution. As long as it is sealed well, it can be kept in the refrigerator and remain in usable condition for several years. 

When you finish mixing A and B, you have to dilute it with distilled water before you spray it to the plant. You have to keep it away from light sources. You can preserve it for nine months, and it will remain in the effective state.

Use protective gear like goggles, gloves, and a safety mask when mixing the solution. It’s toxic, so it’s not good to inhale it, and it can also burn your skin, so watch out. You must use plastic tools. Metallic objects can diminish the efficiency of the solution and modify the composition of the materials.

STS Mixture Procedures

You can begin with pouring 20 ml of distilled water in a plastic cup. Dilute 300 mg of silver nitrate in it. You can get the silver nitrate from Argenpal, which is used for wart removal.

In a separate plastic cup, you can mix the 1.3 mg of STS with 30 mg of distilled water. Do it slowly until the STS is completely dissolved. 

Then mix what’s inside the two cups, and don’t forget to put on protective gear. With all the right steps, you can acquire 50 ml of silver thiosulfate. It can be too potent for marijuana plants, so what you need to do is add 400 ml of distilled water. Shake the mixture until you have 450 ml of solution.

400 ml of silver thiosulfate is still strong for the plants. So just take 100 ml of the solution and add 400 ml distilled water. The 500 ml solution is now acceptable by the plant. 

To get the maximum efficiency, use it within the day that you made it. Place it in a dark, cool place when not in use. It can still be good after 15 days, but you should know that the potency decreases as the day passes by.

Application of STS

Spray STS on the leaves of a marijuana plant and let them soak into the solution. You have to do it in a secluded area so it won’t affect other plants. 

The ideal time to make this application is after 4 or 5 days that you flipped the lights into getting turned off. You won’t fear to damage the plants. Wait for ten days; then, you can do it again.

The parts that received the solution will have male parts with a pollen sac. The pollen from it would be applied to other plants to come up with feminized seeds. The sprayed plant should be discarded as it’s too toxic to use. 

You can pollinate other plants, and it paves the way to combine different genetics. It is a chance that lets you create a feminized hybrid. Those are the things on how to ferminize marijuana seeds. 

Sum it Up

It might sound difficult to some growers on how to feminize marijuana seeds. But with patience and mindfulness, you can do it right. Try doing it with either colloidal silver and silver thiosulfate.

You mustn’t associate stressing the plants in this procedure so you can only come up with feminized seeds. Timing and keeping are essential in terms of flowering and pollen production.
