Blumat Digital Pro Plus Soil Moisture Sensor – Zero Guesswork, Optimal Results
The Blumat Digital Pro Plus takes the guesswork out of watering. Whether you're growing in soil, coco, or living soil, it gives precise moisture readings in millibars – so you know exactly when (and when not) to water. Ideal for dialled-in growers who want healthier roots, less stress, and bigger results.
Why Choose the Blumat Digital Pro Plus?
- Accurate Soil Moisture Readings – Displays root zone moisture as soil tension in millibars
- Works with Any Medium – Suitable for soil, coco, living soil, raised beds, and pots
- Easy-to-Read Digital Display – Clear, simple readout with no digging or guesswork
- Perfect for Living Soil – Monitor moisture without disturbing microbial life
- Built to Last – Durable Austrian design made for long-term use
How It Works
The Digital Pro Plus uses a ceramic sensor to measure the suction pressure (tension) that plants exert to draw water from the soil. Lower readings (0–120 mbar) mean the soil is wet; higher readings (200+ mbar) indicate it's drying out. It shows exactly how much water is available to your roots in real time.

How to Use the Blumat Digital Pro Plus
-
Soak the Sensor
Submerge the ceramic tip in water for at least 30 minutes before first use to remove air bubbles and activate the sensor. -
Insert at Root Depth
Place the sensor into your growing media at the depth your plant’s roots are most active – mid-pot for smaller plants, deeper for large containers or raised beds. -
Allow to Settle
Wait 45–60 minutes for accurate readings after inserting the sensor. -
Take a Reading
Press the power button to display current soil moisture in millibars (mbar). -
Read the Results
- 0–120 mbar: Soil is well-watered
- 120–200 mbar: Ideal moisture range for most plants
- 200–300 mbar: Time to water
- 300+ mbar: Too dry – water immediately
-
Use as Needed
Leave in place for ongoing monitoring or move between containers as needed.
Pro Tip: In living soil, aim to stay between 100–200 mbar to support microbial activity and consistent growth.
Ideal For:
- Living soil growers looking to keep microbial life thriving
- Organic growers avoiding overwatering and root stress
- Hydro-organic and coco growers needing precise water control
- Works perfectly with the Ecothrive living soil range
- Users of Blumat Auto Watering Kits
Why It Matters
Overwatering and underwatering are the most common causes of poor plant health. The Blumat Digital Pro Plus helps you maintain the perfect balance, improving nutrient uptake, reducing stress, and boosting overall yields – especially important in organic or biological systems.
