Vapour-pressure deficit the plant may dry out and die. For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa, ideally sitting at around 0.85 kPa. As a general rule, most plants grow well at VPDs of between 0.8 and 0.95 kPa. In ecology, it is the difference between the actual water vapour pressure and the saturation water vapour pressure at a particular temperature. Unlike relative humidity, vapour-pressure deficit has a simple nearly straight-line relationship to the rate of evapotranspiration and other measures of evaporation. To compute the VPD, we need the ambient (greenhouse) air
What the Water Gave Me (painting) the distance between both of them is dissolved.” In order to bring her viewers as deep into her life as possible, the strong details in her painting made it so that the distance between the self and the other is obliterated so that they are to share in the same experience. Kahlo returned to the same symbols and figures that can be seen in her other paintings. Her toes are what dominate the painting as they are all that is seen of her in this portrait as point up from the water. In the water Frida paints floating remints of
