Sexing your cannabis plants is essential for a successful grow operation. Male plants produce pollen, which can fertilize female plants and produce seeds. This can be undesirable, especially if you are trying to grow sinsemilla (seedless) cannabis.
There are a few key ways to tell if a cannabis plant is male or female. One of the most obvious is the presence of pollen sacs on the male plants. These sacs are located at the base of the flowers and will release pollen when they are mature. Female plants, on the other hand, will have pistils, which are small, hair-like structures that are located at the center of the flowers.
