The fertilization can be realized by way of automatic fertilizing machine and proportionate fertilizing pump. The EC value, PH value and the liquid level of liquid blending chest can be tested by fertilizing machine. Under the control of computer program, fertilization can be executed by overall control of light intensity, time and light accumulation. Meanwhile, the system can clean the filters periodically and correct temp-humidity of the environment.
The proportionate fertilizing pump is relatively simple. It can be connected with liquid-supplying pipes without power and much attention after installation. No matter how the water-flow and pressure fluctuate, the amount of liquid is always strictly in proportion with the water supplied.
