With the low tide, the plants are arranged on a table, which is located above the tank with the nutrient solution.

With the help of a timer, the time intervals are adjusted in which the nutrient solution is pumped from the container for flooding the table and then can proceed.
When flooding the table, your plants take exactly the amount of water and nutrients they need.
With the drainage of the solution, the entire spent air is withdrawn from the root area and fresh air pulled directly down to the roots.

The consumed amount of nutrient solution can be easily measured and allows them to cut their irrigation program exactly to the needs of the plants to achieve optimal yields.
