What Are Nanners in Cannabis?
Nanners are banana-shaped male reproductive structures that can appear on female cannabis plants. They are actually exposed anthers that can develop without forming full pollen sacs. Nanners are most commonly associated with hermaphroditic expression and can release pollen if left unchecked.
How Growers Encounter Nanners
Growers encounter nanners during mid to late flowering when inspecting buds closely. They often appear protruding from within dense flowers and can be easy to miss without careful inspection. Nanners may develop due to genetics or plant stress and are usually spotted during routine flower checks.
Why Nanners Matter
Nanners can pollinate female flowers and lead to unwanted seed production. Even a small number of nanners can affect flower quality if pollen is released. Identifying and managing nanners quickly helps growers protect their harvest and maintain seedless buds.
