Engineered to be an inexpensive solution for the hydroponic or greenhouse grower to maintain the ideal nutrient solution concentration level in the reservoir tank. The HI981413 GroLine Nutrient Dosing System is a complete solution with advanced process controller and a built in chemical dosing pump. Simply insert the probe and injection valve in-line with the re-circulation pump and supply the stock fertilizer to be dosed.
