Food Grade Pvc Hydroponic Vertical Hydroponics Nft System Lettuce For Greenhouse

What is the Nutrient Film Technique (NFT)?

       NFT--- Nutrient Film Technique is a kind of recirculating hydroponic system. it's very low-flow irrigation that feeds the plants in the system. Water is pumped into a flat channel slowly so that a thin “film” of nutrient solution is constantly present.

 How Does NFT Work?

          NFT is designed around that thin film of liquid running through the system. When root systems touch the film, they can drink up the nutrients they need without sacrificing aeration. By balancing the right amount of water flow, nutrients, and oxygen in the system, impressive yields can be achieved with little effort.

         A long flat channel, almost something like a rain gutter on your house, is set up at a slight angle. Holes are drilled in the top of the channel to house net cups with seedlings in them. A reservoir with a water pump sends nutrient solution up to the channel where it flows down pulled by gravity, contacting the plant’s roots along the way. At the end of the channel, the water drains down into the same reservoir where it started. NFT the irrigation runs constantly and only a thin film of water is allowed to drip through the channel.

 Advantanges of NFT:

• Easy to inspect roots for a sign of disease, feed adequacy, etc. due to absence of medium.
• Low water and nutrient consumption.
• Environmentally friendly – minimize the risk of contaminating localized groundwater.
• Unlike media based systems, you can avoid problems related to matters such as supply, disposal, and cost.
• Relatively easy to disinfect roots and hardware in comparison with other system types.
• Plant roots can maintain a uniform PH and conductivity thanks to regular feeding (and associated flushing) that prevents localized salt build-up.

What Plants Grow Best In an NFT System?

             Most growers use NFT systems to grow leafy vegetables like lettuce, spinach, bok choy, kale, and herbs. These plants thrive under constant irrigation.
