What is hydroponic farming?
Hydroponic farming is a growing area of commercial food production. It is also used for home food production by hobbyists. In a hydroponic system, a nutrient-dense water solution circulates through the plants’ roots and replaces the need for soil and traditional fertilizers. This sci-fi-esque technique allows farmers and gardeners to grow food in kitchens, basements, windowsills and roofs.
