Installation Guide
How to Set Up Your System
Takes just a few minutes. Once set up, your plants water themselves.
Step 1
Soak the Sensor
Remove the digital top, soak the bottom for 15 minutes, fill with water and put top back on.
Step 2
Insert at Root Level
Place the ceramic tip in the root zone or near the plant and push it in 30-80% of the way.
Step 3
Wait to Read
Allow 45 minutes after placement for the reading to stabilize.
Step 4
Check mbar
Press the button and use the mbar value to know whether the soil is moist or dry.
Important setup note
The digital top isn't waterproof; it shouldn't be left in the rain without a cap.
Handy mbar guide
0–50 mbar (saturated), 50–100 mbar (ideal/moist), 120–190 mbar (dry/irrigation time).
PROFESSIONAL GRADE MOISTURE METER
Know Exactly When to Water
It reads the soil where your roots live, and tells you one thing: water, or wait.
Reads Where It Matters
The surface dries first. Roots tell a different story. The meter reads the soil that actually feeds your plants.
Perfect for Valuable Plants
Helps protect rare, large or overwintering plants from guessing.
A Real Number
0 mbar means completely saturated. 250 means bone dry. Every reading in between is a precise answer about what your soil is doing right now.
One Press, One Answer
No app. No calibration. No subscription. Push the button, read the screen, water with confidence.
Pairs With Blumat Drip
Fine-tune your Blumat Drip System with near lab-grade tensiometer readings.
Works in Most Soils
Potting mix, living soil, raised beds, and dense substrates. Best in soils with good moisture contact around the cone — extremely airy media like chunky perlite or lava rock can give inflated readings.
What's in the Box?
1 Ceramic Tensiometer Cone
The clay cone is the sensing element. Hollow-cast and fired at over 1,000°C from a precise natural-clay mixture, each one is tested batch by batch. When inserted into soil, the cone measures the same suction your plant's roots feel as they pull water from the earth.
1 CR2032 Battery
The display top ships with the battery already in place — ready to read the moment it arrives. Powers years of regular use, and easily user-replaceable with a small screwdriver when the day comes.
1 Digital Display Top
Screws onto the ceramic cone to read the suction inside in real time. Press the button for an instant mbar reading — from 0 (fully saturated) to 250 (bone dry).
Know When to Water
How to Read Blumat Digital
0 mbar
Fully saturated. Your soil is at maximum moisture — usually right after watering.
50 mbar
Still moist. Roots are drinking comfortably. Microbes are happy.
100 mbar
Starting to dry. Most houseplants are fine here. Check back tomorrow.
150 mbar
Getting thirsty. Most plants want water around here.
200+ mbar
Completely dry and may be drooping. Definitely water now.
