GPP Calculator
This GPP (Grains Per Pound) calculator is specifically designed to help indoor growers understand how to calculate grains per pound—a key metric for estimating the amount of moisture in the air. By entering temperature and relative humidity values, users can quickly determine the GPP value, which indicates the weight of water vapor per pound of dry air.
While this tool provides a convenient starting point, actual grow room conditions can vary. For more accurate and tailored recommendations, it’s best to consult with an HVAC specialist or grow room engineer.
