VPD Calculator (Vapor Pressure Deficit)

Calculates vapor pressure deficit (VPD) based on user-provided temperature and relative humidity measurements. VPD quantifies the difference between the amount of moisture in the air that is actually present and the maximum amount the air can hold at that specific temperature. The tool accepts standard atmospheric readings, allowing users to determine the potential evaporative demand placed upon plant tissues or other moist surfaces under varying environmental conditions. Researchers, horticulturalists, and greenhouse managers utilize this resource to optimize controlled environment agriculture settings. By monitoring VPD, professionals can fine-tune watering schedules and ventilation systems to promote ideal transpiration rates in plants.
