For whatever reason, when colloidal silver solution is sprayed regularly on a female cannabis plants during the early flowering stage, she will grow male "balls" (which are full of female pollen) instead of growing buds.
This allows the grower to collect pollen from a female cannabis plant. You can use this all-female pollen to pollinate another female plant. With two female plants as parents, ALL the seeds will end up being female.
That is why colloidal silver allows can be used create female x female cannabis crosses and produce your own feminized seeds.
as for using it to make female seeds that is this
Why do you want feminized seeds?
When growing regular cannabis and trying to produce seeds, the resulting seedlings end up being about 50% male and 50% female.
This can be a big disadvantage for the cannabis grower because male marijuana plants do not produce very much THC or other psychoactive cannabinoids.
Therefore, when growing cannabis indoors, most growers will throw away all male cannabis plants as soon as they're discovered. However, it's be easier to not have to worry about males since identifying and removing male cannabis plants can be a bit of a pain. Plus, male plants also take up precious space in the grow room until their gender becomes apparent when they are forced to start flowering.
Another problem with male cannabis plants is that they can accidentally pollinate your female cannabis plants which will cause them to concentrate on making seeds instead of making sinsemilla.
Sinsemilla is the term for cannabis flowers/buds that doesn't contain any seeds. Dried sinsemilla is what most growers are trying to produce when growing cannabis.
So what can you do? If you create feminized cannabis seeds, then all the resulting plants will be female and you never have to worry about male cannabis plants again.
While there are a few different ways to create your own feminized cannabis seeds
