Netafim Netajet 4G Nutrigation Systems

Revolutionary Fertigation Control for High-Value Greenhouse Cultivation

The Netafim NetaJet™ 4G is the industry’s most advanced Nutrigation™ system, engineered for high-value greenhouse crops grown in soil or soilless media. Designed with Netafim’s groundbreaking analog dosing channels and an integrated static HidroMix chamber, it delivers unprecedented EC and pH stability, rapid response time, and ultra-precise nutrient control — making it the ideal solution for modern growers chasing yield, quality, and sustainability.

Unlike traditional digital dosing systems, NetaJet™ 4G’s servo-motor-driven analog dosing channels provide seamless 0–100% variable injection. This allows for faster EC/pH stabilization and more accurate nutrient dosing, even in short irrigation cycles typical of greenhouses. The result: healthier plants, more consistent crops, and higher-quality yields.

• Analog Servo Dosing Channels: Continuous variable control (0–100%) for highly responsive, real-time nutrient management
• HidroMix Static Mixing Chamber: Ensures homogeneous nutrient blending before injection into the mainline
• Venturi-Based Suction: Maintenance-free operation with no moving parts
• Rapid EC/pH Stabilization: Up to 50% faster control cycle than digital dosing systems
• Guaranteed EC & pH Accuracy: Enables perfect Nutrigation™ performance for even the most sensitive crops
• Multi-Channel Flexibility: Supports a wide variety of fertilizer and acid injection combinations
• 3-Phase Power Requirement: Ensures compatibility with professional-grade greenhouse infrastructure
• Fully Integrated: Seamlessly connects with Netafim’s NMC range or third-party controllers
• Modular Configuration: Adaptable to a wide range of greenhouse systems, infrastructure setups, and production scales

APPLICATIONS

• Greenhouses with soil or soilless growing media
