Hydroponic farming is making a splash in the agriculture world, especially in urban areas. Agriculture is the top industry in North Carolina, and a growing sector of it is hydroponics: farming without soil or sunlight. Instead, it relies on a water-based nutrient solution. Trevor Spear took up hydroponic farming as a hobby in retirement, and soon found an unexpected passion. Nanue’s Farm is a closed-loop system with nutrient-fed water running every 18 minutes for three-minute periods. Spear joined Jeff Hamlin to discuss the advantages of hydroponic farming.
