Cannabis plants are regarded as dioecious, which means that its male and female reproductive organs are present in separate individuals. Female plants are usually grown in a location without males in order to produce the output that are found usually in recreational and medical marijuana stores: high potency marijuana flowers, known as sinsemilla.
Feminized seeds, in general, are those that are produced by making the monoecious, or hermaphrodites in a female cannabis plant. This can be done through various methods. One is spraying the plant using a colloidal silver solution. It can also be performed using rodelization, as well as spraying gibberellic acid.
