It works by raising fish and plants together in a contained water system. The fish produce waste, which is filtered to remove solids and transformed into nutrient-rich water through a two-step bacterial process. The enriched water is then pumped into a separate tank where seedlings float on soil-free growing beds, illuminated by special LED lamps that provide optimal light for growth. Through this method, crops grow 20 percent faster than plants grown using traditional farming techniques. For that reason, aquaponics is emerging as a sustainable
