I just wanted to highlight a awesome feature in the Pulse Grow App: VPD Guidance.
You just enter a VPD target for your device (in kPa) and the app tells you what temperature or humidity you need in order to achieve that VPD.
To get to it, tap on a device card from the dashboard, and scroll down a bit.
If you don’t see it, you’ll need to update your app.
Set a VPD target in kPa (suggested VPD for different stages of your grow), and then do what the app says to your temperature or humidity.
