WebJul 12, 2024 · High VPD/Low RH: Plants close their stomata, reducing CO2 uptake. Low VPD/High RH: Plants open their stomata, increasing CO2 uptake. If your VPD is too low, then your plants aren’t going to acquire enough nutrients, slowing growth; if your VPD is too high, you’re going close the stomata, rendering your extra carbon dioxide ineffective ... WebHigh VPD usually causes plants to close their stomata in order to reduce water loss and avoid hydraulic malfunction (cavitation). However, this occurs at the cost of reduced carbon uptake during photosynthesis. At the same time, transpiration rate increases with high VPD up to a point after which it either remains high or starts decreasing ...
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.
