WebVPD is a measure of the difference between the amount of water in the air versus the maximum amount of water the air can hold at a given temperature (the saturated condition). It is typically measured in units of kPa or mbars. A low VPD is indicative of high moisture content in the air, and a high VPD is indicative of low moisture content. WebMar 11, 2024 · The resilience of cannabis plants to a high VPD is, of course, determined by genetics. A decreased tolerance to high VPD levels also is the result of suboptimal Calcium levels within the plant tissue. As mentioned earlier, this is a result of too high a VPD during initial growth / stretch, but can also point to an inadequate fertigation program.
