Male cannabis plants grow pollen sacs instead of buds. Male plants are usually discarded because you don’t want them to pollinate the females, which will produce seeds—no one wants to smoke buds with seeds in it.
Male plants can also be used for:
Males are important in the breeding process, but that is generally best left to expert breeders. When pollinating females, males provide half of the genetic makeup inherited by seeds.
Male vs. female marijuana plants
Branches grow out of the main stem and support fan leaves and buds. Growers often train a cannabis plant by topping branches to create more bud sites.
Growers can ensure the sex of their plants by growing clones or the genetically identical clippings from a parent strain. Feminized seeds are also made available through a special breeding process.
The pistil contains the reproductive parts of a flower, and the vibrant, hair-like strands of the pistil are called stigmas. Stigmas serve to collect pollen from males.
Because this occurs when cannabis is under stress, it’s important to monitor plants after they have been exposed to stressors: indoors, high temperatures or light leaks are often the cause; outdoors, a snapped branch might be repaired and then turn into a hermaphrodite.
It should also be noted that male pollen sacs and female flowers develop at the same point on the plant. Both structures emerge from nodes, the point at which branches meet the main stem. So, when you see buds starting to form on some plants, start looking for pollen sacs too.
Cannabis belongs to a minority of species that are dioecious in nature, meaning they produce separate male and female plants. Specifically, it should be noted that only 7% of all angiosperms (flowering plant species) possess this rare and interesting trait.
HOW TO IDENTIFY DIFFERENT SEXES OF CANNABIS PLANTS: SEXING CANNABIS
These protruding structures are designed to capture pollen, which leads to fertilisation. They stick out away from the flower to capture pollen from the air, and to await being brushed up against by pollen-covered insects.
The former features distinctly male and female reproductive organs. Upon close inspection, you’ll notice pollen sacs occupying some nodes, and female flowers residing at others. When the pollen sacs rupture, the pollen will displace into the flowers, and the plant will effectively breed with itself. From there, it’ll go to seed and produce the subsequent generation.
Male plants, in contrast, don’t produce flowers. This makes them less valuable for growers seeking only buds. However, they do produce pollen sacs. These small vessels create the genetic material required to fertilise female flowers and create hybrids. This makes the males extremely important for breeding new cannabis strains.

However, once the plant is about 6 weeks old, it will usually show signs of “pre-flowers” which will alert you to the gender before the beginning of the flowering stage.
Once the clones have established roots, change just the clones into flowering mode by providing them with a light schedule of 12 hours on, 12 hours off
Female marijuana plants take a bit longer than males to show their first signs after being changed over to flowering.
The first stage, “Vegetative” begins when they first sprout, at the beginning of their life.
