Agrowtek GrowControl GCX Instruction Manual page 66

pH & ORP Pumps
pH and ORP pumps must all be on the same dosing pump device (but may be assigned to individual pump
heads.) pH and ORP dosing is performed at a speci c ow rate (ml/min) until the target value is achieved. pH
and ORP dosing can be disabled while nutrient dosing is being performed so that it occurs after the nutrient
dosing as opposed to simultaneously.
To con gure pH dosing, select a dosing pump device (1) and then enable the pH Up (2) and/or pH Down (3)
switch options. When enabled, select the pump head (5) on the pump device to use and enter a ow rate (6)
to dose at.
