The ebb and flow of the nutrient solution in a flood and drain system is intended to maximize the absorption of hydroponic nutrients and oxygen in the root zone for faster growth and higher yields.
Flood and drain hydroponic system.
The flood is when the water and nutrients flow the growing areas flowing over the plants roots.
Next is to work on the upper frame which is where the growing containers and trays are installed.
Place the tank into the bottom frame and cover with the lid.
Basically water and air don t occupy the same space at the same time in the medium and because of this we use the timing of irrigations to find an optimal balance between the air and water content of the medium over time.
The main part of the flood and drain system holds the containers the plants are growing in.
To build flood drain hydroponics you begin at the bottom.
Only periodically rather than continuously.
Basically there are two phases of its operation.
