Yep. Blumat sells a meter, and I found this on its Amazon page:
Step 3
Interpreting the Reading: A display of 0 millibars is equivalent to the meter in a standing cup of water. A display of 750 millibars is equivalent to soil completely void of moisture. For high-value crops like hemp, a reading of 100 millibars for vegetative stage and 120-150 millibars for flowering stage is ideal. These numbers may vary dependent on variety.
Now all we need is the data showing how much moisture a blumat delivers. Whatever it is, it's the correct amount. Or close enough.
