Overview Superior engineering is what sets Dosatron apart from other fertilizer injectors on the market. These injectors are engineered to provide repeatable results with minimal maintenance, saving time and money. Adjusting the amount of fertilizer injected is easy using the ratio-selector stems. Dosatron nutrient injectors accurately inject nutrients or acids (pH Down) while watering your plants. They work without electricity, using only the water pressure from a pump or water mains, eliminating the need for bulky mixing tanks and allowing nutrients to be mixed only when needed. General Information VF refers to the type of seal on the unit. VF seals are designed for use with nutrients and pH Down. If AF seals are required for use with pH Up, please contact us prior to purchasing.
