Hand-Automatic_WebThe Hand-Automatic controls a single pump or valve via a wireless key fob remote carried with a watering technician. Each time the wireless remote’s button is pressed, an exact volume of fluid is dispensed by turning the pump or valve on and off by the FlowDoser.

The Hand-Automatic™ enables common submersible pumps to act like prepaid gas pumps. Make “the count” obsolete, and get the exact volume you want per plant, each time. In use, the watering technician carries your existing hose and watering wand around, but rather that counting seconds off per watering, pushes a button on the wireless remote when positioned over each plant. An exact amount of nutrient solution is pumped, and then automatically stopped. Then, the technician moves to the next plant, and repeats the process.

Each Hand-Automatic™ controls a single pump or valve, allowing it to be easily added to any grow facility with minimal infrastructure changes.
