VPD (vapor pressure diiferential)

Vapor Pressure Deficit (VPD) in cannabis cultivation refers to the difference between the amount of moisture in the air and the amount the air can potentially hold when saturated. It's a crucial metric for growers as it influences the plant's transpiration rates, impacting nutrient uptake and overall plant health. By optimizing VPD, growers can create the ideal environment for cannabis plants to thrive, balancing factors like temperature and humidity to prevent issues such as mold, mildew, and plant stress.
