How to tell if you have a female cannabis

Posted by Kat Ryn On July - 18 - 2014

Determining the sex of your marijuana plant is extremely crucial specially If you are growing it for business purposes or that you want to keep the genome pure as possible. 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. A lot of people think that male plants are useless but depending on how you use them and your growing endeavor, male plants may also be of some use.

Pistils

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. If you notice that 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 which is why most growers opt to cut out or separate the male plants as early as possible. If pollens from the male plant reach the female bud, this will produce seeds. This is only ideal if you plan to cross breed different strains otherwise killing or separating the male plant is advised. Identifying the sex of the plant as soon as possible is important because if the male plant will mature, it will release its pollen and contaminate every female plant in the nursery room. This is extremely frustrating for growers who are not in the 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, there are several other methods used on how to identify if the plant would more likely be a female or male. Separation of both male and female will be much easier after switching the plants from the vegetative (18 hours of light, 6 hours of darkness) to the reproductive stage (12 hours of light, 12 hours of darkness).
