How To Produce Feminized Weed Seeds

Feminization of your marijuana plants is one of the best ways to ensure a successful harvest. There are a number of methods you can use to feminize your plants, including silver thiosulfate, colloidal silver, and rodelization. If you have completed a successful harvest, well done! You have been able to keep your marijuana plants healthy and thriving — and that is probably all you wanted to do up until this point. But what if we told you the next time around could get you an even higher  yield? Feminizing marijuana plants is one way to do this. Keep reading to find out how to do just that.

Making feminized weed seeds

One successful harvest is already doing great, but it means you are ready for learning something new. You have managed to figure out how to have a successful season, and that counts for a lot. Now, are you ready to make it even easier and better? Chances are good that you had a few unexpected obstacles to face during your first season — we have a way to lessen the load of a few of those obstacles.

That’s right, making your own feminized marijuana seeds can actually make your life easier in the long run. You probably noticed that many of your plants, when maturing, became suddenly tall and slim while others stayed short and stout. This is not a random change, of course; it has to do with what sex your plants were. Once this time of the season comes around, you can begin to plan for the future and decide which plants you can reproduce to create feminized marijuana seeds.

Sexing marijuana plants

Before you can even begin to think about making feminized marijuana seeds, you will need to accurately identify the gender of each of your plants. The males will show signs of change first, as soon as the number of hours of daylight decreases past a certain point. Males will start developing growths that resemble buds and are greenish white and egg-shaped. These flowers will soon be emitting a puff of pollen, making it clear and obvious that the plant is, in fact, male.

The females will start developing a couple weeks after that. You can identify female plants by their buds, which are white and resemble cactuses. The buds will grow steadily for around a month until they are heavy, aromatic, sticky, and much bigger.

Before all these changes in the males and females take place, you can already gauge a pretty good idea of which is which. The males are generally the tallest plants in your garden (simply because taller males mean their pollen spreads further), and they die before the females do.

Marijuana pollination

The key concept you need to understand once your plants are reaching maturity is what exactly pollination is. If you leave your plants as they are, the males will undoubtedly pollinate the females, which means the females will then “focus” their resources on producing seeds rather than buds. Unfertilized females, on the other hand, focus every ounce of energy they have on producing many fat, sticky, THC-rich buds. In other words, unfertilized females are the best for producing the largest amount of high-quality marijuana.

This means that you should actively decide which females you want to fertilize and which you want for your particular harvest. If you are only going for a successful harvest, then you should simply remove the male plants as soon as you are able to identify them.

Producing seeds

Making seeds is easiest when you are growing indoors. The best way to fertilize your plants is to begin by taking one male out separately and changing its lighting patterns. The females should still have 24 hours of light per day, but change your male’s lighting to 12 hours of light and 12 hours of darkness. This is what “tricks” the male plants into entering its flowering phase and then begin producing pollen. Once you start seeing the pollen being produced, simply get some pollen from the flowers with a piece of paper and seal it in an envelope. Store it in the freezer to maintain freshness.

The females should be kept vegetating for as long as possible. Only when you finally decide your females are ready to flower should you use the stored pollen. Choose which female you would like to reproduce — preferably one that has had a successful growing season or exhibits qualities that you prefer — and then “paint” the pollen (mixed with water) onto just one of the female’s cola.

After about half a week, start exposing your female plant to 12 hours of sunlight and 12 hours of darkness. Make sure you are aware of the seeds’ progress so you can remove them at the ideal time. When they are mature enough to remove, they will be some shade of brown. Just remove them with your fingers and freeze them in a (clearly labeled) container. They will remain fresh for as long as you keep them in the freezer.

Feminizing your marijuana seeds

If you fertilize your plants the normal way described above, you will end up with the unfortunate average ratio of males to females, which is 70% male and 30% female. If you feminize your marijuana seeds, however, you will make the ratio as close to 100% female as possible — and that means big results for your next harvest.

There are several methods for doing this, or you can simply purchase feminized marijuana seeds online. The company should be reputable, however, or else it may end up being a waste of money. If you prefer to do it yourself, you can pick from the following methods: silver thiosulfate, colloidal silver, and rodelization.

Silver thiosulfate

The silver thiosulfate method is somewhat new, although it is already one of the most common methods to use. This is due to its high rate of success. It uses what’s called a Silver Thiosulfate Solution, or STS. Silver thiosulfate is actually a mixture of sodium thiosulfate and silver nitrate, and it causes a stress response in marijuana plants. Because marijuana plants often naturally respond to stress by changing gender, this can be used to our advantage.

You should only subject one or a few of your female plants from the same strain to this treatment. They should be nearly mature when you apply the STS. All you have to do is separate the chosen plant from the rest of your plants, spray it with the STS, and then put it back where it was to grow. It will begin appearing stressed, turn brown, and will generally appear unhealthy. After less than a week, however, it will start to perk up — in just one month it will have become male.

The next step is to pollinate the other females with this male plant — just shake the male over the females, and the seeds that they produce will be feminized. This is due to the fact that the male plant actually has female pollen.

Colloidal silver

Pure silver and distilled water are the main ingredients you will need to successfully carry out this method. Simply put the pure silver (also called colloidal silver) into the distilled water, and then spray it onto the female plants. They will start forming male pollen sacs, which have the effect of a regular male’s pollen sacs but are actually genetically female.

Unfortunately, it isn’t quite that simple. You will also need a 9-volt battery, a connector, alligator clips, and a soldering iron. Attach the battery and the connector, and then solder the alligator clips to the black and red wires. Connect them to the silver — coins, for example — which should go into the distilled water. Careful not to let the alligator clips make contact with the water itself. This process will allow the silver ions to float around in the distilled water.

 

Let it sit like this for seven hours or more in order to elevate the concentration of the silver. This is then the mixture that you spray onto your female plants, thus getting feminized seeds. Spray once per day when the flowering phase has begun. You should see results within two weeks. Then fertilize the plants the same way you would normally, as described above.

Be sure never to consume or smoke any part of a plant that came in contact with the colloidal silver solution. The pollen is safe, but the plant matter that directly touched the colloidal silver solution is not. When in doubt, throw it out.

Rodelization

This is another method that takes advantage of the marijuana plant’s natural response to stress. If a female plant has reached the end of her life without being fertilized, she will naturally develop male pollen sacs. This evolved as a means of the species’ self-preservation. The seeds from this response will naturally be female because only female genetics was actually used to create them.

Rodelization is the natural method of achieving something like the above two methods describe. It simply requires you to keep the female plant in its flowering phase for much longer than you normally would, causing the plant to begin self-pollinating. Once you see the pollen sacs, you can remove the pollen and use it to “paint” female colas, as was described already.

This is easily the least reliable of the three methods, and you might not end up with feminized seeds anyway. It will also keep the plant being treated from having an ideal harvest, so it is indeed a risk. It’s the preferred choice for organic growers, however, since it is all natural.
