The reproductive organ of the male cannabis plant. The stamen produces pollen which carries the male plant’s genes and travels through air to pollinate a female plant.

“If you see stamen early in the grow cycle, you know those are males and you have to get rid of them.”

What is a stamen?

The stamen is the reproductive organ on male cannabis plants. It is made up of anthers, or pollen sacs, and filaments, which hold up the anthers. When a male plant matures, pollen sacs open and release pollen into the air. 

Identifying stamen is useful when cannabis plants are young to determine if they are male. Generally, males are separated or discarded so as not to pollinate female plants, unless one is breeding plants or creating new strains.
