Description

The Netafim Netaflex 5G Greenhouse Fertigation System is an automated fertigation system designed for efficient nutrient dosing and irrigation management in greenhouse soil and soilless growing systems. Powered by the GrowSphere™ MAX controller, it uses an open-tank pre-mixing system to blend nutrients before injection, helping provide accurate and uniform fertilizer application across irrigation cycles.

Dual EC and pH sensors provide fast regulation and stabilization, while closed-loop injection control continuously adjusts dosing through analog feedback. The system supports adaptive dosing, configurable injection channels, and variable injection rates, with flow capabilities from 3–64 m³/h (13–282 GPM) and fertigation flows from 25–600 L/h. GrowSphere™ MAX also enables local and remote system management, real-time monitoring, analytics, and reporting. The Venturi-based design has no moving parts, helping reduce maintenance requirements and downtime.
