Sensor-based irrigation control with real-time web monitoring and control. Built for plant researchers, greenhouse operators, and teams who can't afford guesswork.
Designed for experiments where a tight control of soil moisture variability between pots is crucial. From a single bench greenhouse experiment to large-scale modular operation, exactH2O adapts to your scale.
Automated irrigation triggered by real-time soil moisture thresholds — not timers. Water when the plant needs it, stop when it doesn't.
Web-based monitoring and control from any device-desktop or mobile. Real-time sensor readings, historical data plots, system status, and irrigation history in one interface.
High-resolution VWC, electrical conductivity, and temperature sensors with substrate-specific calibration for several types of media.
Modular architecture supports growth from a single bench to larger multi-zone deployments. Controller, network, and irrigation requirements are confirmed for each facility.
"The precision irrigation system enabled developmental stage-specific drought treatments while continuously maintaining target soil moisture conditions."
Researchers at Michigan State University used the ExactH2O irrigation platform to study how drought timing affects switchgrass physiology, metabolism, and downstream biofuel production. Plants were grown in 8-liter pots under greenhouse conditions and assigned to well-watered control, vegetative drought, flowering drought, or senescence drought treatments.
The system was used to monitor soil moisture content and irrigate individual pots when soil moisture fell below programmed thresholds. Control plants were maintained at 25% VWC, while drought treatments were reduced to 1% VWC during specific developmental stages and then re-watered.
Continuous soil moisture control allowed researchers to impose precise developmental stage-specific drought and connect those treatments to gas exchange, chlorophyll fluorescence, metabolomics, biomass composition, and fermentation outcomes. The study showed that switchgrass maintained biomass under severe short-term drought, while drought timing strongly influenced metabolic responses and biofuel yield.
