Feminized cannabis seeds (female seeds) are seeds that are genetically modified to produce only female plant. For all the growers, the interesting part of the harvest is the female flowers or buds. The male flowers are only used to produce seeds. Traditionally the growers must germinate an amount of seeds at least double of the final quantity of plants requested. For the modern indoor grower this mean also to throw away a great quantity of electricity and fertiliser for nothing. Ministry of Cannabis has found a solution for this problem. Using substances, such as gibberellic acid and colloidal silver, the breeders of Ministry of Cannabis have managed to ensure that their female plant will produce male pollen. In this way, given that both parents are indeed a female, only the X chromosomes are passed to the offspring. This is why the seeds that are produced in this way can only generate female plants (99,99%).
