Readings you can trust
Soil moisture accurate to ±2% without drift, plus nutrient strength (EC) and temperature. Built for salty hydro media and dry field soils, not only open-field row crops.

Every drop,
under control.
Drift-free root-zone sensing, and control decisions made on-site. Start with one sensor and the free app, then scale across rooms, benches, fields, and facilities. The same stack covers leak detection and air quality when buildings need the same discipline.

The problem
You can't control what you can't see.
01
Timers don't know the root zone
A schedule is excellent at being on time and indifferent to conditions. Between manual checks, containers and fields swing wet and dry, whether you're running 500 acres or 20 greenhouse zones.
02
Salinity confuses the reading
Most commercial probes were designed for row crops, not high-EC hydro or heavily fertilized media. In those conditions salinity interferes with water-content readings, and a confident number can still be the wrong number.
03
Dead zones on site
Remote fields, basements, and outbuildings often have no WiFi or cell. Cloud-only systems go quiet in the one place automation matters most: on-site.
The loop
Sense it. Decide it. Water it.
A closed loop that lives on your site, from probe to pump, and keeps running when the internet doesn't.
Control that lives on-site
Growbud Edge makes control decisions on-site. When the network drops, irrigation and automation keep running. The operation never needed a login.
From source to valve
One system from probe to pump. Sense, decide, and move water on the same platform, or hook into the irrigation, feeding, and building gear you already own.
The hardware
One sensor is enough to start.
Buy a single Dro or Vero, pair it with the free app, and prove the readings before you commit to a full deployment.

Intelligence
Sees it coming. Acts in time.
Growbud learns your crop: it predicts dry-downs before they happen, spots stress in leaf photos, and folds every reading into one clear watering call, on-site, in real time.
AI predictions
Sees dry-down hours before the plants show it, so watering starts on schedule with the crop, not after the fact.
Reads your leaves
Crop photos surface stress, deficiency, and disease before soil numbers move, and that evidence feeds watering and feeding decisions.
One clear picture
Soil, climate, and crop photos resolve into one signal you can act on, without three dashboards and a spreadsheet reconciliation.
Survey tool
Survey the site before you instrument the whole floor.
One Dro is a portable survey tool: find wet spots, dry ridges, and EC buildup, then place permanent sensors where the data actually earns the install.
Start with one DroPlace one Dro in the field, bed, or container you want to benchmark.
2
Walk high, low, wet, and dry zones to compare VWC, EC, temperature, and humidity.
3
Use the map of readings to decide where permanent sensors and controls belong.
Applications
From the root zone to the mechanical room.
Cultivators use Growbud for moisture, EC, and irrigation that responds to the crop. Facilities use the same stack for leak detection and air quality, wired into the BMS already on site.
Free app
Every sensor has somewhere to report.
Pair a single sensor, review live readings, and add gateways and controllers when the site needs continuous monitoring or automation.
