I have an hydrangea in a «self watering» vase (a Lechuza Cube) and I use a Parrot Flower Power to monitor soil moisture.
The soil moisture level sensor stays constant (17%-18%), watering the vase generates a peak for a very short time, but then the moisture level drops to the usual value (17%-18%)
A similar sensor works as expected in a «normal» vase.
The Parrot Flower Power application is continuously telling me to add water, as the action has no effect on the measured moisture level.
- Are similar values normal in a self watering vase?
- Is the soil too dry for an hydrangea?
