What is VPD (Vapor Pressure Deficit) and why is it important in agriculture

Vapor pressure deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated.

A high VPD) (Vapor Pressure Deficit) means the air is very dry and plants lose more water.

A low VPD (Vapor Pressure Deficit) means the air is very humid and plants lose less water.

This is crucial in farming because it directly affects how much water plants lose.

Plants lose water through small openings on their leaves. This process is called transpiration. Essentially, transpiration helps plants to move nutrients, cool down the leaves, and control osmotic pressure.

But, we need to control transpiration. If plants lose too much water, they can get stressed and not grow as well.

VPD (Vapor Pressure Deficit), changes based on the type of crop and how it’s grown. In general, a VPD that’s too high or too low can hurt plants. This can lead to less photosynthesis, stomata closing, and a higher risk of fungal diseases.

So, it’s important to watch and adjust the VPD to keep it right for the crop.

NIDO ONE V2 makes it easier. This smart device lets you control and automate all the key factors for plant growth, including VPD and air temperature.

With NIDO ONE V2, you can set the VPD and temperature you want from the NIDO app. Then, the device takes care of the rest.

NIDO ONE V2’s algorithms will automatically adjust the greenhouse’s humidity and ventilation based on the set VPD and temperature.

Plus, you can watch the VPD and the temperature of the greenhouse in real time. You’ll also get notifications and tips to help make your cultivation better.
