Korean Tower System.Sanghyun Jin, a Korean customer, used to use the NFT hydroponics system. Now he wants to upgrade the hydroponics tower system. The customer is curious about the working principle of the column and the configuration of the column system. We shared the video on the working principle of the column with him, and told the customer that our column would be equipped with a water pump. If we planted it on a large scale, we could also build a water and fertilizer system for the customer, build a waterway pipeline, and use timers and automatic control irrigation.
