This salad concept grows its own lettuce through an on-site hydroponic farm
🌱 Neon Greens, a quick-service salad restaurant in St. Louis, Mo., features its own 400-square-foot vertical hydroponic farm, producing an equivalent yield of three acres of 80 lettuce varieties used in their salads. Founder Josh Smith emphasizes radical transparency in sourcing, highlighting that conventional lettuce is often two to three weeks old when it arrives from California and Arizona. The hydroponic farm requires substantial machinery maintenance and was installed using a 150-foot crane. Neon Greens focuses on lettuce due to its high yield and quick growth, avoiding crops like kale with longer maturation times. The restaurant makes an environmental impact by saving on water—using only 2,500 gallons annually per farm versus 900,000 gallons in six months for traditional farming—and practices recycling and composting. While currently less cost-efficient due to operating a single location, Smith aims to reduce lettuce costs through expansion and economies of scale.
