Measure soil moisture tension directly in the root zone with the Blumat Digital Moisture Meter. Designed for potting mixes, containers, raised beds, and living soil, this digital tensiometer reads in millibars (mbar) so you can compare moisture conditions, check drybacks, and verify irrigation performance with real data.
New to soil moisture tension? Read our Measuring & Managing Moisture in Living Soil to learn what mbar readings mean, how soil moisture tension differs from volumetric water content (VWC), and how sensor placement affects what you measure.
Available Options +
Meter Only — Base unit for direct soil moisture tension readings.
Meter + Protective Cap — Adds protection for the electronic meter head.
Meter + Protective Cap + Battery — Includes a spare CR2032 3-volt battery.
Complete Kit (Meter + Cap + Battery + Coring Tool) — Includes the Blumat Coring Tool (1" wide, 11"+ long) for clean installation with minimal soil disturbance.
How It Works +
The ceramic cone equilibrates with the surrounding soil and the meter displays soil moisture tension in millibars (mbar). Lower numbers indicate wetter conditions; the reading rises as the soil dries and water becomes harder for roots to extract.
After installation, allow about 30 minutes for a useful initial reading. Full equilibration can take longer. Once the meter is conditioned, moving it between beds or containers with similar moisture levels can provide a useful comparison within several minutes.
Use the meter to establish repeatable wet and dry reference points, check moisture at root depth, compare different locations in a bed, or verify and fine-tune a Blumat irrigation system.
Important Notes +
The electronic meter head is water-resistant, not waterproof. Do not submerge it or expose it to standing water.
The protective cap should not be seated directly into soil. Trapped humidity can damage the meter head.
For best comparisons, pay attention to installation depth, soil contact, and location in the root zone.

Once we got the Blumat watering system dialed in, the plants basically water themselves. Hand watering isn’t something we have to think about anymore, and it’s taken a lot of work off our plate while keeping moisture consistent.

Adding Blumats to our living soil beds has been one of the best things we have done for consistency and efficiency in watering. With one of the most time consuming and labor intensive tasks off the table, we now have more time to work with the plants themselves, allowing us to focus on canopy, environment, and plant health.

We’ve been using Blumat in our rooms and couldn’t be happier. Blusoak in flower and capillary mats in veg have made watering incredibly consistent and stress-free. The plants stay happy, everything runs smoothly, and we’re saving a huge amount of time day to day. Simple, reliable and super effective!

Living soil comes down to consistency, and getting Blumat dialed in across a double-tier facility changed everything for us. We’re now seeing repeatable moisture across thousands of square feet, with healthier biology, stronger roots, less labor, bigger canopies, heavier yields, and way less time spent chasing drybacks.

Blumats have changed our farms daily life drastically! It’s taken 6 hour hand watering daily to 30 minute quick teas twice a weeks. It’s an absolute Godsend! Much Love To Sustainable Village.
