WebVPD is calculated using temperature and relative humidity. A general VPD range for a greenhouse is from 0.45 kPa to 1.25 kPa. The higher the VPD, the drier it is in the greenhouse. The lower the VPD, the more moisture is present. At the upper limit of the VPD range, the crop may not be able to keep up with transpiration demand. WebThe comparison shows that the optimal control of a greenhouse tomato crop production system without heat storage and autonomous availability of CO 2 , when simulated over four characteristic days, improves the energy efficiency by 8.5%.
