VPD
VPD (Vapor Pressure Deficit) is a measurement tool used in indoor farming and greenhouse management to track the relationship between temperature and humidity. In simple terms, it helps farmers understand how well plants can take in water and nutrients. Think of it like a comfort index for plants - just as humans feel uncomfortable when it's too humid or dry, plants need the right balance to grow well. Farmers use VPD readings to create the perfect growing environment by adjusting their climate control systems.
