Overview

Deep liquid flow hydroponics is a facility cultivation bed that holds 5 to 10 centimeters of nutrient solution, placing the crop roots in it, and taking corresponding measures to supplement oxygen.

The advantage is that there is no fear of water and power outages midway, the rhizosphere has a great buffering effect, the rhizosphere environment is less affected by the external environment, and has good stability, which is conducive to crop growth and management.

However, the requirements for facilities and equipment are high, and the supplement of oxygen in the rhizosphere is very important. Once infected with soil-borne diseases, they will spread quickly and cause great harm.
