The environmental factor that has the greatest effect on transpiration is humidity. High humidity levels reduce the rate of transpiration because there is already a lot of moisture in the air, making it harder for water to evaporate from the plant's leaves. Conversely, low humidity levels increase transpiration as the drier air creates a larger gradient for water to move out of the plant.
