When it comes to growing cannabis, one of the most important things to know is how to differentiate between male and female plants. Male plants produce pollen, which can fertilize female plants and cause them to produce seeds. This can be undesirable for growers who want to harvest sinsemilla, or seedless cannabis. Female plants, on the other hand, produce buds that are high in THC and other cannabinoids, which are the compounds that give cannabis its psychoactive effects.
There are a few key ways to tell the difference between male and female weed plants. One of the most obvious is the presence of pollen sacs. Male plants will have pollen sacs on their flowers, while female plants will not. Pollen sacs are small, round, and yellow or brown in color. They are located on the stems of the flowers.
