Feminized (seeds) refers to cannabis plants that have been bred to produce only female strains. Such cannabis plants have been modified to produce only bud-bearing female plants.

The female cannabis plant is the most coveted for its production of terpenes and cannabinoids in its flowers. Tetrahydrocannabinol (THC) creates the desirable psychoactive experience known as a ‘high’ that users find pleasurable and beneficial. However, other cannabinoids also excreted by female plants are also believed to assist in the treatment of numerous medical conditions.

Growers like feminized seeds because they are guaranteed an all-female crop for cultivation.

Maximum Yield Explains Feminized

Feminized seeds were first cultivated by growing female cannabis plants that possessed both male and female characteristics. Known as hermaphrodite or hermaphroditic plants, such early cannabis plants were predominantly female but if the plant underwent stress, such as water deprivation or sudden temperature drops, the plant would enter a survival mode. In survival mode, the female plant would start to produce male staminate flowers so that pollination of the plant’s female pistil flowers could easily occur.

By growing both male and female flowers, the cannabis plant guaranteed it’s lineage survival through seed production.

Researchers have found that the use of colloidal silver helped to physically modify the seeds to further guarantee the production of only feminized seeds.

What Does Feminized Seeds Mean?

When you wonder what does feminised seeds mean, the key is in the sex!

Feminized seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized seeds mean that they are treated to make them female (hence the name feminized) so that all the seeds can be used to get flowers. Breeders usually sell feminized seeds for their strains because they are easier to grow and are too unstable to reproduce, although some people use plants from feminized seeds to get cuttings, it is advisable that they use females from Regular seeds.

What Are “Feminized” Cannabis Seeds?

Feminized cannabis seeds are produced in a way to make sure that all the resulting plants are female (since only female cannabis plants make buds).

“Regular” (or non-feminized) seeds will produce about half male, and half female plants.

Having male plants can be an asset to a breeding program, but having to watch over and throw away half the plants can be a waste of time and space for growers who just want to grow their own supply of bud!

By starting your grow with feminized cannabis seeds from a reputable breeder, you can stop worrying about plant gender altogether, and know that every single one of your plants is going to be female and make buds!

How Do Breeders Make Feminized Seeds?

The way breeders create feminized seeds is they breed two female cannabis plants together, which means that all the resulting offspring will be female. This is done by spraying developing flowers with a substance that changes flower development (often colloidal silver or gibberellic acid). This process is used to force one of the female plants to start producing pollen sacs just like a male plant.

By harvesting the pollen sacs and using the “female” pollen to pollinate buds of a different female plant, you are giving the resulting seeds only female genes (there is no “father”), so none of the seedlings end up being male.
