Keeping the air around your plants at an optimal VPD level will lead to maximum plant growth. Using the Growbud app you can set a low and high threshold for VPD, and the app will alert you if the sensor detects conditions are out of range.
The Growbud app has a default range, and in general if you keep your VPD close to 1.0 kPa your plant will be okay. To unlock maximum plant growth you can research your plant’s optimal levels for each stage of growth and use the Growbud app to help maintain those levels. In the event you get an out of range VPD alert from the Growbud app you can follow these steps:
Low VPD Action Plan: To increase your VPD and unlock maximum plant growth it is advised to increase the air temperature, decrease the humidity, or both until your VPD is back to a good level.
High VPD Action Plan: To decrease your VPD and unlock maximum plant growth it is advised to decrease the air temperature, increase the humidity, or both until your VPD is back to a good level.
