In fact, cannabis plants can be male or female (and sometimes hermaphrodite), which leads to huge yield differences. Indeed, male plants can be used to propagate this species through pollination, and their fibers are widely used in the textile market, while female plants are mainly used to produce inflorescences. Feminized seeds are specialty cannabis seeds that have a 99.9% chance of producing female cannabis plants.


In nature, cannabis plants are all born under dioecious species, that is, there are some male and female specimens that cross to create new specimens. Regular seeds are the ones that can produce both male and female plants, and the grower cannot control their sex. The probability of female plant births is the same as the probability of male plant births, hence the 50% / 50% proportion. For this reason, growers who want to harvest excellent buds will opt for feminized seeds to be sure that they only have female plants in their cultivation. Farmers who choose regular seeds, in general, use them for large seed production.
