When analysing your grow room data, it’s important to look for trends. This way you can reduce the worst hours in your crop cycle and increase plant vitality.
In this case, what you see is a growing trend in VPD. Not only is the trend going up but also you can see the “waves” are getting higher. At the same time the humidity is going down. The up going trend of the VPD and the down going trend of the humidity are correlated directly. However the increasing of the total delta VPD (from 0.1kPa to 0.3 kPa) is a result of not enough soil moisture!
This way you can spot plant stress increasing circumstances (drought), through analysis of climate related variables!
