Moreover, the plants in NFT systems can take up nutrients quickly and easily, which leads to faster growth and higher yields.
- No soil needed: Hydroponic NFT systems use a soilless growing medium, which eliminates the need for soil. This also means that there are no soil-borne pests, diseases, or weeds, making the plants healthier and easier to grow. Additionally, soilless methods are more environmentally friendly as they eliminate soil erosion, runoff, and contamination.
- Year-round growing: Hydroponic NFT systems allow you to grow crops throughout the year. You have the power to manipulate the growing conditions and provide your plants with the environment they need to grow optimally, regardless of the season. This means that you can enjoy fresh, locally grown produce all year round.
- Space utilization: Hydroponic NFT systems can be used to grow crops in small spaces, such as balconies, rooftops, or even indoors. This is because the system doesn't require large amounts of space to grow plants like traditional soil farming needs.
- Higher yields: Hydroponic NFT systems tend to produce higher yields compared to traditional soil farming. This is because the plants receive the exact nutrients and water they need, which leads to faster growth rates and healthier plants. Additionally, as NFT systems create a controlled environment, there is less risk of crop loss due to unpredictable weather conditions or pest infestations.
- Lower maintenance: Hydroponic NFT systems require less maintenance than traditional soil-based farming. This is because they don't require regular tilling, fertilizing, or watering. The nutrient solution can be automated with a timer, so a grower doesn't have to check on the plants every day. Consequently, this saves time, money, and energy.
In conclusion, hydroponic NFT systems are an excellent choice for growers who want to take advantage of the benefits of hydroponics. They are efficient, space-saving, and eco-friendly, providing year-round fresh produce with minimal effort. The advantages mentioned above make NFT systems highly popular and one of the most sought-after systems by growers worldwide.
Components of a Hydroponic NFT System
A Hydroponic NFT system is a method of growing plants without soil in a nutrient-rich water solution. The system uses a continuous flow of water, which ensures the plant roots are moist and keep receiving the necessary nutrients. Here are the essential components of an NFT hydroponic system.
- NFT CHANNELS: The NFT channels provide the base where the plants will grow. They are typically made of PVC pipes in which the water passes through the plants' roots. The channels have a slight tilt to ensure that water flows continuously and does not stagnate in the system. They can be customized as per the user's preference and the kind of plants they want to grow.
- WATER PUMP: A water pump is used to circulate the nutrient solution. The pump moves water from the reservoir to the top of the NFT channels and then back to the reservoir in a loop. It is important to choose a pump that matches the size of your hydroponic system and can provide enough water flow for your chosen plants.
- RESERVOIR: The reservoir is a container that holds the nutrient solution and water. It is essential to keep the water in the reservoir at a constant level. The volume of the reservoir depends on the number of plants and the size of the hydroponic system. An ideal reservoir is made of a material that does not leach chemicals into the water or damage the plant's roots.
- NUTRIENT SOLUTION: A nutrient solution is a mixture of water and nutrients, which is supplied to the plants through the NFT channels. The solution must contain the essential elements required for a plant's growth, such as nitrogen, potassium, and phosphorus. It is essential to monitor the pH level of the nutrient solution regularly to ensure that it is within the desired range.
- GROWING MEDIUM: A growing medium is not always necessary in NFT systems. However, some plants can benefit from a growing medium to support their roots. Commonly used mediums are coconut coir, rock wool, perlite and vermiculite. Before choosing a growing medium, it is essential to research if it is suitable for the plants you want to grow and your hydroponic system's specifications.
- NET CUPS: Net cups are used to hold the plants in place and prevent them from falling over. They are usually made of plastic and placed in small holes drilled in the NFT channels. The cups have an open bottom allowing the roots to grow into the nutrient-rich water solution. It is important to choose cups that are the right size for the plants you are growing.
- PH TESTING KIT: A pH testing kit is essential to ensure that the pH level of the nutrient solution is within the appropriate range for the plants grown. A pH level outside the plant's optimal range can cause nutrient deficiencies or toxicity, eventually stunting their growth. The testing kit can either be a digital meter or colorimetric testing kit. Either way, it must provide accurate test results.
When choosing the components of your hydroponic NFT system, it is important to research and choose high-quality, durable and reliable components to ensure the success of your hydroponic garden. It is essential to keep the system clean and well-maintained to prevent diseases or pests, and ensure the longevity of the components.
