The marijuana plant or cannabis plant is an hermaphroditic plant. This means that there are male and female plants. The female plant has flowers and resin and is used for the cultivation of marijuana. The male plant only produces pollen, which has no further application.
A male plant can fertilize a female plant so a female plant will produce seeds. The result of the production of seeds by the female plant is that energy is lost and this results in a smaller harvest. For this reason male plants are not used and removed. Therefore we only sell female seeds.
When the conditions are optimal, You could store the cannabis seed somewhere between 3-10 years if they are stored dry and dark.
The best result is reached by first germinating the seeds. This is better because when you let the seeds start in a controlled environment, it increases the chance that the seeds germinate well. When you directly put the seeds in the ground without germinating them first, there is a high chance a part of the seeds will not come up.
