Turn grower experience into irrigation strategies that can be executed, monitored, and adjusted to changing weather.

The NETDA ecosystem

Solutions for every greenhouse need

From irrigation and fertigation to monitoring, analytics, and greenhouse climate control.

Documented feature

NETDA Smart Irrigation

Schedule-based or weather-responsive irrigation using ETc, crop coefficient Kc, and grower-defined strategies. Configure irrigation thresholds, cooldowns, drainage targets, EC, pH, and fertilizer programs for each growth stage.

NETDA hardware and solutions

From controllers to integrated fertigation systems

NETDA brings together controllers, sensors, hydraulic components and software to help growers manage irrigation, nutrient delivery and operational data.

Central controller

NETDA Smart Irrigation Controller

The controller operates outputs according to scheduled irrigation, manual commands or a grower-defined weather-responsive strategy.

  • Four relay outputs for compatible valves, pumps or auxiliary equipment.
  • Two inputs intended for pressure and flow-related signals.
  • RS485 interface for temperature, humidity and light sensors.
  • Local operation alongside software-based monitoring and control.

Illustrative design only. Confirm the production hardware specification and wiring before purchase or installation.

Irrigation and fertigation

Water and nutrient control for every irrigation event

Connect water and nutrient tanks, pumps, valves and distribution lines. Each irrigation event can carry its own timing, duration, water/fertigation mode, target EC/pH and nutrient program.

  • Zone-specific schedules and crop-stage settings.
  • Reusable nutrient programs and channel configurations.
  • Operational history and sensor readings where supported.
  • Local control or integration with a separate controller.

Flow capacity, pressure, nutrient channels and EC/pH control depend on the installed system.

System integration

Designed around real greenhouse workflows

Water passes through the pumping and measurement assembly. Nutrient channels are dosed according to the configured system, and the mixture is distributed to the selected irrigation zones.

  • Inputs: water, nutrient tanks, sensors and grower settings.
  • Decisions: schedules, recipes, durations and safety conditions.
  • Outputs: pump/valve commands and operational logs.

Smart irrigation software: the grower remains in control

NETDA is not merely a timer that opens valves. It helps growers translate their experience into a strategy that can be simulated, reviewed and refined.

01. Fixed schedules

Set time, duration, zone, water or fertigation mode, EC/pH and nutrient program. A familiar and practical starting point.

02. Weather-responsive ETc

Use climate data and crop coefficient Kc to estimate water demand. Growers configure irrigation thresholds, cooldowns and duration limits.

03. Preview and simulation

Explore irrigation events using yesterday's data, today's conditions or sunny/rainy scenarios before enabling ET-based automation.

04. Nutrient programs

Store nutrient-channel recipes and target EC/pH values by crop stage, then adjust them as growing conditions change.

05. Dashboard and history

Review temperature, humidity, light, VPD, ETc, irrigation logs and EC/pH readings where sensors are available.

06. Reusable crop data

Save and refine crop-stage parameters, irrigation strategies and fertilizer programs for future growing cycles.

A practical adoption path

01 · Keep current schedulesStart with the irrigation practices already familiar to your team.
02 · Observe conditionsCollect climate, ETc and irrigation data.
03 · Compare forecastsSee what NETDA would schedule under the same conditions.
04 · Enable when readyRefine thresholds and adopt automatic ET irrigation after verification.
In development

NETDA Smart Climate Controller

A hybrid time-and-condition approach to greenhouse climate control. For example, at 11:00, if temperature and VPD exceed grower-defined thresholds, a fan may run for a specified duration. Planned devices include circulation fans, ventilation fans, fogging, shade screens and lighting. This solution remains in development and testing.

Growers define the strategy. NETDA executes it.

NETDA does not replace grower expertise. Growers set water requirements, growth stages, irrigation windows, and operating limits; the system uses climate data to support execution.

01 · Configure

Select crop, growth stage, Kc, irrigation thresholds, and fertilizer programs.

02 · Calculate

Track weather, calculate ETc, and forecast irrigation events based on settings.

03 · Validate

Compare forecasts, irrigation history, and crop response to refine settings.

More than automatic valve switching

Scheduled irrigation

Set fixed irrigation times, durations, EC, pH, and fertilizer programs.

ETc-based irrigation

Accumulate weather-based water demand and irrigate according to grower-defined thresholds and cooldowns.

Preview before activation

Simulate irrigation schedules using yesterday’s data, today’s data, or selected weather scenarios.

History & charts

Review irrigation history, weather, and operating data to support adjustments.

Crop data

Store growth stages, irrigation strategies, and fertilizer programs as reusable templates.

Flexible control

Keep scheduled and manual irrigation available alongside weather-responsive operation.

From real growing conditions

Tested in everyday growing conditions

NETDA is tested in real cultivation conditions, including a tomato greenhouse using substrate across multiple seasons and uneven seedling stock. The developer observes crop response, fertilizer costs, and weather-responsive irrigation to improve the product.

Our belief: technology should serve the farms growers already have, not only premium facilities.

Results from one farm may not apply elsewhere; yields and costs also depend on cultivar, area, nutrition, weather, and management.
