Replace or refresh the top water distributor in your FlowGrow tower with a compatible FlowGrow Flow Cap.

The FlowGrow Flow Cap sits at the top of the tower and spreads nutrient water from the centre hose across the tower levels. Water then flows down through the system, reaching plant roots before returning to the reservoir.

  • Distributes water from the centre hose down through the tower
