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 (song) What the Water Gave Me (song) "What the Water Gave Me" is a song by English indie rock band Florence and the Machine from their second studio album, "Ceremonials" (2011). The song was written by lead singer Florence Welch and Francis "Eg" White, and produced by Paul Epworth. It was released on 23 August 2011 as the first promotional single from "Ceremonials". After the band performed the song in Berkeley, California, on 12 June 2011, the studio version premiered on Florence and the Machine's official website. Welch decided to name the song "What the Water Gave Me" after seeing the
