A client from Saudi Arabia, who wants to personally invest in a hydroponic farm, focuses on the return on investment. The customer wants a greenhouse area of 1000 square meters to grow some green leafy vegetables for sale. After learning about all of our products, the customer ultimately wants to choose between an NFT device and hydroponic tower system. The NFT system has low investment, simple operation, high yield and good planting effect of the tower system, but the investment is higher. The client eventually chose the tower system and set up his own hydroponic farm with our assistance.
