What Are Pistils in Cannabis?
Pistils are the hair-like reproductive structures that emerge from the calyx of a female cannabis flower. They are part of the plant’s reproductive system and are responsible for catching pollen during pollination. Pistils typically change color as the flower matures, often starting light-colored and darkening over time.
How Growers Encounter Pistils
Growers encounter pistils early in flowering when identifying plant sex and monitoring flower development. Pistil color and shape are commonly observed throughout flowering to gauge maturity and potential harvest timing. Changes in pistil appearance can also indicate pollination or environmental stress.
Why Pistils Matter
Pistils help growers identify female plants and assess flower development. While pistil color alone should not be used to determine harvest readiness, it provides useful visual cues when combined with other indicators. Healthy pistil development is associated with proper flower formation and bud growth.
