Disclosed is a pneumatic liquid nutrient dispensing assembly for hydroponically cultivated plants. The assembly includes a reservoir and a liquid nutrient dispenser disposed within the reservoir. The liquid nutrient dispenser includes a substantially coaxial pump body with inner and outer tubes forming a distribution end having a distribution hub and an inlet end having a liquid intake structure. Airflow in an annular duct formed between the walls of the coaxial tubes enters the inner tube through an annular passage and carries liquid nutrient within the inner tube to the distribution hub. Distribution members fluidly connected to the distribution hub direct a flow of liquid nutrients and air to one or more plants.
