VPD Buddy Slider

VPD Chart Generator & Much More

Achieving the right VPD in your grow room will guarantee and increase in the yield and essential oil content of your crops.

VPD is calculated from the temperature and humidity and the resulting number in kPa means next to nothing to the general user.

Using our app you can see your current room VPD plotted on a VPD chart with easy to understand coloured bands , you can assess conditions easily at a glance and react accordingly.

For example if you temperature is too high and taking you too far down the chart in Bloom and you can not lower the temperature you can scan horizontally (humidity) on the chart until you reach a number that puts you back in your desired colour band and then raise your rooms humidity to that level and visa versa.
