How to produce feminized cannabis seeds

Buds are ready to get pollinated when they look like little bunches of white hairs

To those who say this type of reproduction just doesn’t seem right, the evolutionary strategy of plants using only female and hermaphrodite plants to breed is actually pretty common and is known as gynodioecy. One example of a plant that only reproduces this way is a flower found in Canada and the US called Lobelia siphilitica, also known as the Great Lobelia. Obviously, this reproduction method isn’t exactly the same as artificial feminization since the pollen production is caused naturally instead of induced chemically, but examples of gynodioecy show that a female flower-based breeding population can exist in the wild even when no plants are purely male.

Yes, it’s possible to use just female plants and feminized seeds for further breeding, with one major caveat.

How to produce feminized cannabis seeds

The Silver Thiosulfate Solution, also known as STS, is one of the most common methods of generating female marijuana seeds. It is very effective in allowing female marijuana seeds to be available to marijuana growers. Using this method will feminize the seeds in the best way possible, making more available on the market for growers. The solution is made of a combined silver nitrate and sodium thiosulfate. The solution result is a hormonal response to stress found in the marijuana plant. Because of this, gender change is triggered.

Generally speaking, there is no way that you can determine the difference between male and female marijuana seeds in the initial stages of planting. In addition, you are also not able to change the gender of your marijuana deeds. The concept of having feminized marijuana seeds is to maximize the female seeds that will be part of your marijuana crop. Why would you want female marijuana plants? Well, these are known to have a higher level of THC content. Male plants have reduced THC content and for that reason, female plants take precedence over male plants. With cannabis seed feminization, there are several pollination techniques that the marijuana grower can use for a favorable outcome.

One of the simplest ways to produce feminized cannabis seed is to pollinate your plants yourself. Some cannabis strains can produce male flowers when the colas have reached late ripeness. Side note: Ed Rosenthal, master grower and proud member of the CTU faculty, prefers to harvest plants around this time. Harvest the pollen by using a clean and small painting brush to transfer the pollen into a metal or glass container or in small amounts directly on the flowers.

You can do all of this yourself, but the marijuana plants have to be wisely chosen. You should only take female plants from a single cannabis strain that is almost mature. Then you would separate the plant from the bunch and spray the plant with STS. Allow it to dry and then replace it, making sure it sits alongside the other plants in the bunch.

Gibberellic Acid

Gibberellins are hormones that affect cannabis plants throughout their growth cycle. Some gibberellic acids such as GA3, 4, 5, and 7 can induce the growth of male cannabis flowers when sprayed directly on female plants before the flowering period. Most growers use GA3, the most widely available and effective of the gibberellic acids. Use a solution of 0.1 gram of GA4 per liter of distilled water. Ed Rosenthal recommends spraying the top of plants for five days in a row then changing the photoperiod to induce flowering.

It’s important to learn how to feminize seeds so you can save time on your grow. When the traditional fertilization methods are used to grow your marijuana plants, you have less control over the gender of future marijuana plants. That is why many marijuana growers take extra steps so you receive female marijuana plants at the time of harvesting. To do it yourself, feminize seeds prior to your harvest.

If you are going to do the feminization of marijuana seeds yourself, then there are methods that you can use namely:

Buying the Right Cannabis Seeds

Large-scale and home growers have harnessed the power of certain chemicals that can induce male flowers in female marijuana plants. These chemicals are used to hinder ethylene production. Ethylene is a plant hormone that helps cannabis plants ripen and produce female flowers. When ethylene production is stalled, female flowers aren’t produced. Keep in mind, these chemicals must be directly applied to each branch that you want male flowers to grow.

With the colloidal or pure silver method, you also need distilled water. Use a spray bottle to apply this mixture to your female marijuana plants, but you have to do it when the plants are flowering. Pollen sacs will be formed. The pollen has female genetics, allowing the marijuana seeds to produce female plants.
