Knowing the gender of the cannabis is crucial,specially when the purpose of growing is for business.Only female marijuana plants produce buds which most grower need and are after for while male plants on the other hand do not produce buds. Many people think that male plants has no use but it depends on how you grow them.


During flowering time, female marijuana plants usually takes longer to show their sex signs than male plants. Female marijuana plants will start to show one or two whispy white hairs where their buds are also going to form. They generally first show up where the main stem attaches to the individual bumps or ‘branches’. If a female plant is kept in the vegetative stage long enough, then she will start to show signs of hairs and whips even before growers start to alter its light schedule. Once there are white hairs and whips on your plant, then you know that it is a female plant.

Buds vs Pollen

The male plants produce pollens while female plants produce buds. The female flower turns into buds that’s why most growers separate the male plants as early as possible. If pollens from the male plant reach the female bud, this will produce seeds. Ideally if you plan to cross breed different strains otherwise killing or separating the male plant is advisable. Knowing the gender of the plant in an early stage is important because if the male plant will mature, it will release its pollen and contaminate every female plant in the nursery room. This gives frustration to growers who are not into cross breeding path because female plants who have been pollinized will most likely yield buds with lesser quality that I would have. For expert growers, they used several methods on identifying the plant’s gender. It will be easier to separate the gender of the plants after switching them from vegetative (18 hours of light, 6 hours of darkness) to the reproductive stage (12 hours of light, 12 hours of darkness).
