Active Aqua Hydroponic Systems

Grow Flow Ebb & Flow System

Grow Flow Controller


Active Aqua’s Grow Flow is the most efficient ebb & flow system on the market. With the Grow Flow’s easy-to-program controller unit, you can pretty much “set it and forget it.” And since your pumps are only pumping a short time each day, the system is extremely reliable and effcient. Just set the fill drain cycles and the controller unit does the rest!

As for safety, the Grow Flow is the only unit available with fail-safe overflow protection. If the float valve stops operating, the LED indicator lights up on the control panel and the emergency shut-off valve automatically shuts down the system, preventing any spillage or damage to your growing area.

Have bigger plans? Expand your system to up to 48 growing modules with the convenient Grow Flow or Grow Flow 2.0 Expansion Kit, or you can build your own system from the ground up by purchasing all the components individually.


Available as a 12-site Complete System, or create a custom setup by purchasing individual components.

  • Connect 6 to 48 growing modules to a single system
  • Adjustable float ladder and emergency shut-off valve
  • LED emergency indicator light
  • Each growing module consists of one outer bucket and one inner bucket – making it easy to lift and move plants
  • ¾" (13 mm) tubing and fittings make for fast flood and drain times
  • Water pumps operate on 120 V
