NFT Lettuce Greenhouse with İska Sera

NFT Lettuce Greenhouse with İska Sera: An Innovative and Efficient Agricultural Solution

NFT (Nutrient Film Technique) is a modern method used in hydroponic farming, offering increased productivity while conserving water. At İska Sera, we provide more efficient and sustainable agricultural solutions through our NFT lettuce greenhouse systems. In this system, lettuce plants are nourished not with soil but through a continuously flowing nutrient solution. Water and nutrients are delivered in a thin film that directly reaches the plant roots.

Advantages of NFT Lettuce Greenhouse Systems

1. Efficient Water Use:
   The NFT system recirculates water in a closed loop, minimizing water loss and delivering only the amount required by the plants. This method is particularly advantageous in regions with limited water resources. For example, water use in NFT systems can be up to 90% more efficient compared to traditional soil-based farming.

2. High Yield and Rapid Growth:
   Since lettuce plants absorb nutrients directly from the solution, they grow rapidly and deliver high yields. Scientific studies show that lettuce in NFT systems grows 30–40% faster than in traditional soil-based production. On average, an NFT lettuce greenhouse can yield between 10 to 12 tons annually.

3. Protection from Pests and Diseases:
   Because no soil is used, soil-borne diseases and pests are virtually eliminated. This allows lettuce plants to grow healthier while also reducing the need for chemical treatments. Studies have shown that plants grown in NFT systems exhibit greater resistance to diseases.

4. Controlled Environment:
   The NFT system minimizes the impact of external environmental factors by delivering nutrients and water directly to the plants. Managing variables like temperature, light, humidity, and nutrient levels results in a more efficient and consistent production process. Controlled environments inside greenhouses also allow for stable, year-round harvesting.

5. High Yield in Limited Space:
   NFT systems are ideal for areas with limited space, making it possible to achieve high production even in small areas—such as in urban farming. For example, approximately 20–25 lettuce plants can be grown per square meter, delivering up to 50% more yield than traditional farming methods.

Average Planting Capacity

The average planting capacity in an NFT lettuce greenhouse varies depending on system size, greenhouse efficiency, and applied techniques. In İska Sera’s NFT systems, 20–25 plants can be cultivated per square meter. In a 1,000 m² area, it is possible to grow approximately 20,000–25,000 heads of lettuce per year. Thanks to the efficiency of water and nutrient use in NFT systems, water consumption can be reduced by up to 90% compared to conventional methods.

Scientific studies confirm that NFT systems offer faster growth rates than traditional soil-based farming and help plants become more resistant to disease. A 2018 study showed that lettuce grown in NFT systems grew 40% faster and used 70% less water than soil-grown counterparts.
