It is closed with a small control valve to form a pressure difference between the control valve before and after, so that your dissolved fertilizer can enter the venturi in the water. Then enter the water supply pipe.
Flow through the venturi by vacuum suction, and the fertilizer solution is uniformly sucked into the pipeline system from the open fertilizer tank for fertilization. Make your operation easier and simpler.
If the fertilizer concentration is stable, there is no extra power, saving your time and resources!
Product range: small area fertilization such as greenhouse.
