Ebb and Flow System

The ebb and flow system, also known as the flood and drain system, involves periodically flooding the plant roots with nutrient solution and then allowing the excess to drain away. This is achieved by temporarily raising the container holding the plants to flood the roots and then lowering it to allow the solution to drain. This cycle is typically controlled by a timer. The ebb and flow system works well for a variety of crops and is particularly suited for larger plants.

Nutrient Film Technique (NFT) System

The NFT system is a hydroponic setup that involves a continuous flow of nutrient solution over the plant roots, creating a thin film of water that provides both water and nutrients. The plants’ roots are suspended in shallow channels or gullies, and the nutrient solution is pumped through the channels, allowing the roots to absorb what they need. This system is often used for growing herbs, lettuce, and other small plants with shallow root systems.

Drip System

The drip system is one of the most versatile and widely used hydroponic setups. It involves periodically dripping nutrient solution onto the base of each plant, allowing it to trickle through the growing medium and reach the roots. This system utilizes individual drippers or emitters for each plant, providing precise control over the amount of water and nutrients delivered. The drip system is suitable for a wide range of plants and can be easily scaled up or down.

Aeroponic System

The aeroponic system is a more advanced DIY hydroponic setup that involves suspending the plant roots in air and periodically misting them with a nutrient solution. This setup provides optimal oxygenation to the roots and allows for faster growth and higher yields.
