Both the colloidal silver method and the rodelization method are described in detail below if you scroll down. Rodelization is a more “natural” way to get seeds, while colloidal silver gives you more control of the feminization process. Each of the methods has its pros and cons.
These self-pollinated seeds will have gotten both sets of genes from the same female plant, so both parents will be female, and all resulting seeds with be female.
You should, therefore, destroy the plant after the pollen has been collected.
This issue with this method is that some strains of plants never seem to grow male characteristics naturally. Additionally, with this method, you’re selecting for plants that have a natural genetic tendency to show male characteristics. This can possibly produce offspring that are more likely to show male characteristics themselves which may or may not be what you’re going for. Lastly, even when you do get male pollen sacs from a marijuana plant in this way, there tends to be a lot less pollen than from a typical male plant.
Make Your Own: You can make your own colloidal silver generator at home. The diagram below should illustrate what you need to do.
Colloidal Silver is created by submerging two pieces of pure silver in distilled water, and then running an electric current between the two pieces of silver. The electric current will cause silver ions to be deposited in the water which creates a colloidal silver solution.
After the balls start forming
Unlike the rodelization method described below, you are not selecting for plants that show hermaphrodite traits. The genes of the plant are completely unaffected. This method will also produce a lot of pollen consistently compared to the rodelization method.
There are two main methods to create your own feminized cannabis seeds: the colloidal silver spray method or using rodelization.
