Hydroponic NFT channels consist of a series of long, shallow channels that allow nutrient-rich water to flow through them. Plants are placed in each channel and their roots are left suspended in the flowing water. The flow rate of the water is controlled, ensuring that the nutrients are evenly distributed to the plants and that oxygen can reach their roots. Inhydro is one of the best hydroponic companies in the world for NFT systems, providing high-quality NFT channels with excellent control over the flow rate of the water.
