NFT DFT Vegetable Glass Greenhouse

As one of professional manufacturer, Spring Agri Equipment would like to provide you high quality NFT DFT Vegetable Glass Greenhouse.  The roots of vegetables grow in the nutrient solution, which can avoid possible residues of pesticides, heavy metals and other pollutants in the soil, so the vegetables are clean and safe in the NFT or DFT vegetable glass greenhouse. Hydroponic vegetables also have their limitations, such as large initial input, high demand for nutrient solution ratio technology, and susceptibility to microbial contamination. So if you plan to put into production, please contact a professional greenhouse construction company and professional planters for guidance, TOP GREENHOUSE will provide you with factory discount price.

The following mainly introduces NFT hydroponics or DFT hydroponics technology.

NFT（Nutrient Film Technique）

NFT is a method of hydroponics in shallow flowing nutrient solution, with shallow nutrient level (1-2 cm), simple design and construction, and low input cost. The NFT hydroponic system consists of three parts: environment control, water and fertilizer control and circulation pipeline.

● Simple structure, small investment, low cost.

● Easy to install by yourself with appropriate liquid supply device.

● Reduced water and nutrient consumption.

● It is convenient to clean and disinfect the equipment

● Nutrient solution supply is small and easy to replace

● Reduce pests and diseases

● balance the Water, oxygen, nutrition

● Reduced water pollution

NFT hydroponic system has become the choice of many scale model manufacturers, because of its low input cost in the initial construction cost savings, so that enterprises quickly enter the profit model. The NFT hydroponic system is also suitable for small businesses and individual growers to choose, and does not require too much investment in the early stage, but can grow high-quality vegetables with the NFT vegetable glass greenhouse.

DFT（Deep Flow Technique）

DFT hydroponics system immerses the plant's roots in a nutrient solution to a depth of 10-20 cm, which circulates through a water pump to provide water, nutrients and oxygen to the plant. Because of its large-scale and modern facilities, deep-water floating culture, truly realizes the factory production of vegetables, and the product quality is stable.

Key Advantages of DFT Systems

(1) Large amount of nutrient solution, good buffering

(2) Nutrient composition, pH and temperature are relatively stable.

(2) Easy to move the vegetable,during operation because the crop floats on the nutrient solution

(3) High land utilization rate.

(4) Nutrient solution recycling, save water and fertilizer.

(5) Automatic control and annual production can be achieved.

Key Disadvantages of DFT Systems

(1) High cost of facility investment.

(2) The amount of nutrient solution used for the first time is large and the operating cost is high.

(3) Disinfection and disease-free operation requirements are strict, otherwise once infected diseases will be difficult to control

(4) It is only suitable for planting small plant type crops, and the management of large plant type crops is inconvenient.

(5)High technical requirements require professional agro technician
