How do Nutrient Film Technique (NFT) systems prevent root bound and ensure healthy plant growth?

NFT systems prevent root bound by providing a continuous flow of nutrient-rich solution over the roots, which are typically held in a sloping trough or channel. This design allows the roots to grow freely and absorb nutrients as needed. The constant flow of solution also prevents the buildup of toxins and ensures that the roots receive a consistent supply of oxygen. Additionally, NFT systems can be designed to accommodate different plant types and growth stages, making them a versatile option for hydroponic farming.
