EVO-20 DLI Meter
Track the total light plants receive across the day with Daily Light Integral instead of relying on one momentary brightness reading.
U.S. Design Patent D1,126,017
Stop guessing. Understand your plant’s root zone.
EVO10 is a leave-in soil monitor designed to show how moisture, root-zone temperature, and daily sunlight change over time—not just at one isolated moment.
Dual stainless-steel probes
Up to 6 months of history
DLI sun-level classification
Leave-in monitoring
No Wi-Fi required
Rain-resistant housing

Why ordinary spot checks can miss the bigger picture
A single probe reads one small location. EVO10 is built to stay in place and reveal what happens across the root zone and over time.
Dual probes sample a wider soil area
Local wet pockets, dry areas, perlite, roots, and uneven soil structure can affect a single-point reading. EVO10 uses two separated probes to create a broader sampling field and provide a more representative root-zone picture.
- Less dependent on one isolated wet or dry spot
- More stable readings around the active root zone
- Better suited for long-term in-soil monitoring
Designed to stay in the soil long term
EVO10 uses two same-material stainless-steel probes and is designed for continuous contact with moist soil. This helps reduce the corrosion risks associated with some mixed-metal single-probe structures.
- Dual stainless-steel probes
- Long-term leave-in structure
- Less repeated disturbance near delicate roots
See the trend, not just a spot reading
Daily and monthly history makes it easier to understand drying speed, watering cycles, and how different pots or soil mixes hold water.
Build a real watering routine
EVO10 records changes continuously, so you can see how fast the soil dries after watering and when it reaches the level where your plant actually needs attention.
- Water at the right time
- Know your soil’s drying speed
- Compare daily and monthly patterns
What your moisture curve can reveal
The shape of the moisture trend can help growers recognize soil that stays wet too long, dries too quickly, or follows a repeatable watering cycle.
Track root-zone temperature over time
Soil temperature can be very different from the air temperature. EVO10 records temperature trends so you can identify heat buildup, faster drying, and potential root stress.
- Daily temperature trend
- Monthly temperature history
- Root-zone data, not just weather-app estimates
Simple Bluetooth access
After the first setup, EVO10 records independently. Your phone does not need to remain connected. Reconnect whenever you want to read the sensor and review stored data.
- No account required
- No Wi-Fi or internet gateway needed
- Read stored data when you reconnect
Engineered for more stable long-term readings
EVO10 combines probe structure, short measurement pulses, and alternating polarity to support reliable long-term soil monitoring.
01
Same-material probes
Two stainless-steel probes help reduce mixed-metal galvanic effects.
02
Short measurement pulses
Measurements are applied briefly instead of continuously energizing the probes.
03
Alternating polarity
Polarity alternates to help reduce one-sided polarization and electrochemical buildup.
Leave it in place. Disturb the roots less.
Repeatedly inserting and removing a spot-check meter can disturb soil structure and delicate roots. EVO10 is designed to remain installed near the root zone.
Why soil can get hotter than the air
Sunlight can heat pots and soil far above the surrounding air temperature. Monitoring the root zone helps you see why soil dries quickly and when placement or watering may need adjustment.
- Identify rapid heat buildup
- Spot potential heat stress earlier
- Adjust watering and placement using real root-zone data
Know your plant’s daily sun level
Ordinary soil meters may show only Low, Medium, High, or a single instant Lux value. EVO10 tracks Daily Light Integral across the whole day, helping you understand the total sunlight your plant actually receives.
- Full Sun
- Partial Sun
- Partial Shade
- Shade

Is EVO10 the right tool for your measurement task?
Compare EVO10 with EVO-20 and EVO-Solar. Choose EVO10 when root-zone conditions such as soil moisture and root-zone temperature are part of the question, rather than measuring only Daily Light Integral or solar irradiance.
