Introduction to Hydroponics Systems: What Are They and How Do They Work?
Hydroponics is a cultivation technique that uses nutrient solutions instead of soil to provide plants with essential nutrients. Instead of growing in soil, the plants develop in an aqueous medium where all the nutrients are directly available to the roots. This allows the plants to grow faster and healthier, as the roots can access everything they need efficiently.
There are various hydroponic systems, each with its own characteristics and ways of operating. Some systems, such as the Flow and Reflux System, are known for their versatility and ease of use. Others, such as the Nutrient Film Technique (NFT) System, are ideal for large-scale production. Choosing the right system is crucial to maximizing yields and ensuring that your plants thrive. The system you choose should suit your specific needs, such as the type of plant you want to grow, the space available and your budget.
Let’s take a look at some of the main hydroponic systems available, including the Flow and Reflux System, the Drip System, the Nutrient Film Technique (NFT), Deep Water Culture (DWC) and Aeroponics. Let’s explore how each one works, their advantages and disadvantages, and how they compare in terms of cost and scalability.

Nutrient Film Technique (NFT) System: Ideal for Mass Production
The Nutrient Film Technique (NFT) system is widely used in commercial hydroponic growing environments, especially for leafy greens and herbs. It works by continuously circulating a thin layer of nutrient solution along the roots of the plants, which are suspended in an inclined channel. This technique allows the roots to always be in contact with the nutrient solution, but without being completely submerged.
Advantages
Water saving: NFT is known for its water efficiency. The nutrient solution is continuously recirculated, which significantly reduces waste.
Suitability for Green Leaves: This system is ideal for fast-growing plants with small roots, such as lettuce and spinach, which benefit from the constant availability of nutrients.
Limitations
Sensitivity to Failures: NFT can be sensitive to failures in the pumping system or in the circulation of the nutrient solution. If the flow is interrupted, the plants can quickly suffer from a lack of nutrients and oxygen.
Not Ideal for Larger Plants: Plants with larger roots or that require more support may not adapt well to NFT. This system is more suitable for leafy crops and smaller plants.
Deep Water Culture (DWC): Simplicity and Productivity
The Deep Water Culture (DWC) system is one of the simplest and most productive methods of hydroponic cultivation. In this system, the plants are placed in a container where their roots are completely submerged in an oxygenated nutrient solution. An air compressor keeps the solution rich in oxygen, which is essential for healthy root growth.
Pros
Rapid Plant Growth: As the roots are constantly in contact with the nutrient solution, plants can grow rapidly. This direct contact with nutrients and oxygen promotes robust and healthy development.
Low Maintenance Cost: The DWC system is relatively simple in terms of maintenance. There is no need for complex irrigation systems or expensive equipment. The main task is to monitor the nutrient solution and ensure that oxygen is constantly supplied.
Cons
Risk of Lack of Oxygen: If the oxygenation system fails, the roots can quickly become deprived of oxygen, which can harm the plants. It is therefore crucial to keep the air compressor in good condition and to monitor the nutrient solution.
Smaller Variety of Compatible Plants: DWC is best suited to plants with roots that are not too large. Larger plants or those with more complex roots may struggle with this system, which somewhat limits the variety of plants you can successfully grow.
The DWC System offers a simple and efficient approach to hydroponic cultivation, ideal for those who want fast plant growth and easier maintenance, it is important to be aware of the continuous supply of oxygen and the limitations of compatible plants.
Aeroponics System: High Technology for High Value Crops
Aeroponics is a hydroponic growing system that uses a highly technological and innovative approach. In this method, the plant roots are suspended in the air and sprayed with a fine mist of nutrient solution. This technique ensures that the roots receive a large amount of oxygen and nutrients, promoting exceptional growth.
Benefits
Maximum Nutrient and Oxygen Efficiency: Aeroponics provides incredible efficiency in the delivery of nutrients and oxygen to the roots, which can result in very fast and healthy plant growth.
Lower Water Consumption: As the nutrient solution is applied as a mist, water consumption is minimized, which makes this system very sustainable.
