The Marijuana Pollination Process

A cannabis plant’s bud site contains sub-units, an arrangement of buds where individual female flowers combine to create buds. Female flowers are also referred to as pistils. Pistils are where the stigmas are generated which pollination develops.

Prior to maturation, the cannabis plants bud site is comprised of sub-units that are getting ready to expand. During this stage, it is no longer extending and the bud sites are beginning to establish. The strain will determine when the progress begins. This could happen right smack in the middle of the flowering stage.

Every single sub-unit is made of a bud. The tops of the sub-units are where baby flowers develop during the flowering stage. You can tell when this stage occurs because of the small stigmas on the single flowers. Stigmas are quite thin with white hairs springing out of the pistil.


Once the male cannabis plant get to the females stigmas, reaching the egg cell of the female plant that is in the pistil, the pollination process begins. The seed comes from pollination. Another name, and a popular one, for non-pollinated marijuana plants without seeds is sinsimilla.

There is a part of the female flower named glandular trichome that makes resin on the flowers and leaves. It will sort of resemble a ball sitting on top of a stick. Be very careful with how you handle the buds because they are quite fragile and can easily tear off if they are not touched carefully.

The more mature the pistil is, the larger it will be because their stigmas are continuing to seek pollen. Take note that there are smaller leaves under the pistil called a stipule. When the stigmas have brown or red hairs sticking out, it is able to take pollen from a male flower.


As one of the many stages of your cannabis plants growth cycle, harsh weather conditions such as rough winds or hard rainfall will kill stigmas. Once the pistils fully develop, the stigmas die making it the pistils get large and become deprived of their pomposity.

So, once it reaches the point where it is about to die, the pistil will no longer draw in pollen. The hairs will start to resolve quite quickly once the pistil and stigma have died. Notice that during the process of the pistil’s growth cycle their bodies have both white and brown hairs that do not follow are harmonized pattern of growth.
