How it works

The Blumat Digital uses tensiometer technology to show when your soil needs watering, all at the touch of a button. A tensiometer measures the ‘suction power’ of your soil, providing you with readings to determine how easy it is for the plants' roots to access water.

The Blumat Digital tensiometer works best when left in one place. You will have a stable reading 12 hours after inserting into the soil. They are not designed to be moved around regularly.

How to use Blumat Digital

1. Soak the grey tube with ceramic cone in water for at least 15 minutes.
2. Use water that has been boiled and left to cool to minimise the oxygen content.
3. Fill the tube with water and attach to the digital display head.
4. Press and hold the "On" button for several seconds until "000" or "---" is displayed.
5. Insert the Blumat Digital into the soil and wait at least 45 minutes.
6. Press the "On" button, digital reading will be displayed.

Note: for a more accurate reading, wait 12 hours after inserting into the soil.

For light-loving, fast-growing, fruits flowers and vegetables in organic living soil, the following readings are ideal:

• 120-150 mbar for establishing young plants.
• 100-120 mbar for early vegetative growth.
• 80-100 mbar for late veg and flowering/fruiting.
• 100-150 bar for late flowering/fruiting.

These numbers are a guide and can vary dependent on the plant species and environmental growing conditions.

(High value = Dry; Low value = Wet. A reading of 0 millibars is equivalent to fully saturated, achieved when the ceramic cone of the meter is in a cup of water. A reading of 750 millibars is equivalent to dry soil with little to no moisture content.)

It is important to avoid getting the Digital top part wet. If using outdoors, or in hand watering situations where the Blumat Digital may get watered over, use with the Blumat Digital Protection Cap.
