What are the main advantages of The Robuster?

  • · No need to turn it on. theRobuster starts working when water is flowing.
  • · Automatic dosing. theRobuster tracks water flow and doses the required amount of fertilizer.
  • · Precise dosing. If you set the fertilizer dosing amount at 10 ml per gallon, it doses precisely 10 ml per gallon.
  • · The Robuster works well with a wide range of water flows. Minimum water flow is 0.5 GPM
