Hydroponic System is a system of growing crops without soil, often called soilless farming. In the hydroponic system, the plant roots grow in a liquid nutrient solution or inside the moist inert materials like Rockwool and Vermiculite. The liquid nutrient solution is a mixture of essential plant nutrients in the water. The plant roots are suspended either in the static liquid solution or in a continuously flowing nutrient mixture. The hydroponic growing system requires continuous attention to the crops, unlike the traditional farming system.

Advantages
Higher productivity than the traditional farming system, the plant nutrients are effectively used, and there is no wastage.

• The hydroponic system is a controlled climate system in which the crops can grow year-round.
• Water utilization is low when compared to the traditional farming method, up to 80-90 percent lower.
• The crops are grown in a closed space, which eliminates the attack of pests and insects.
