Benefits

• Simplified Batch Mixing: Eliminate the need for a 3-step batching system to save valuable time and space. Our system injects the correct ratio of nutrients while filling the batch tank simultaneously, eliminating the mixing step of other batch mixing systems. In addition, no mixing tank is required which means the recipe is delivered straight to the holding tank. One less tank to purchase and use floor space.
• Nutrient Control: Recipe flexibility allows for all nutrient formulations to be fed from one system for an entire facility, whereas leading competitors mandate separate systems for each recipe or have limited recipe ranges.
• Integrated Batch Monitoring: Effortlessly integrate with accuracy using our Batch Tank Monitoring Kit.
• Feature Packed Software: Capable of utilizing Copilot, Blueprints and all Growlink OS2 features.
• Flexible Solutions: The NDK provides flexibility and versatility for batch tank applications
  using many of the top nutrient lines available.
• Built for Expansion: Equipped to integrate 3rd party sensors including level sensors and more.
