Dilution Solutions' Water-Powered Nutrient Delivery System DAB Starter Kit includes all the parts you need for the inlet of your Nutrient Delivery System, and is used in in conjunction with DAB Pumps, or pumps with VFD Control. The Nutrient Delivery System DAB Starter Kit does not include a pressure regulator – for systems with inconsistent or high pressure situations, the Standard Starter Kit should be used. To Complete the LO-FLO Nutrient Delivery System, you will also need Dosatron Injectors, Mixing Chamber Kit(s), the pH/EC Monitor Kit or END Kit, and the Water Hammer Arrestor Kit.
