What are the advantages and disadvantages of the hydroponics system?
Hydroponics allows plants to be grown without soil or with minimal soil, making it a sustainable farming method.
It enables vertical farming to produce more food in less space, recirculation of water and fertilisers, and control of climatic parameters like temperature, humidity and light.
However, it requires initial investment in equipment like aerators, pumps, and growth media.
It also needs regular monitoring of water quality parameters like pH, dissolved oxygen, and nutrient levels.
The system depends on electricity for pumps and aerators, and requires technical knowledge for maintenance.
Explanation
The chapter explains that hydroponics is a solution for growing healthy food in an environmentally friendly manner. Advantages include: precision farming with controlled nutrient supply, vertical farming to utilise space efficiently, water and fertiliser recirculation, and climate control in polyhouses. Disadvantages implied include: need for equipment (pumps, aerators, net pots), regular maintenance, monitoring of pH and dissolved oxygen, and technical expertise.
