What Are Pollen Sacs in Cannabis?
Pollen sacs are the reproductive structures found on male cannabis plants that produce and release pollen. They appear as small, round or oval sacs that develop in clusters near nodes and branch junctions. When mature, pollen sacs open and release pollen into the air.
How Growers Encounter Pollen Sacs
Growers encounter pollen sacs when identifying male plants or inspecting for hermaphroditic traits. They are often spotted during early flowering before they open. Because released pollen can fertilize female plants, pollen sacs are typically removed or isolated quickly when found.
Why Pollen Sacs Matter
Pollen sacs are responsible for pollination and seed production in cannabis. For growers aiming for seedless flowers, identifying and managing pollen sacs is critical to preventing unwanted seeds. Understanding pollen sac development helps growers protect flower quality and maintain control over breeding.
