One of the things that makes Superior Fresh so different from other land-based fish farms and glass growing houses is that they are connected and create an ecosystem that feeds each other. The water from the fish house is pumped to the glass house and feeds the plants in 140-gallon pools of water. As the plants grow, they take the nutrients from the water and “clean” it, and the clean water gets pumped back to the fish house to go into the fish tanks.
This innovative way of using water for fish to grow in and to provide water and nutrients to leafy greens means that Superior Fresh uses much less water than other fish houses and other indoor plant houses.
Their lettuce is organically grown with 1/30th the amount of water that traditionally farmed lettuces need to grow (for ever 30 gallons of water farmers need to grow lettuce in the ground, Superior Fresh uses just one gallon of water). And because the farm is under glass, they are able to create the perfect growing conditions year-round and use about 1/20th the amount of space that a traditional farm would use to grow the same amount of lettuce.
Superior Fresh grows between 15 and 20 different varieties of leafy greens (lettuces) and herbs all the time. Some of the different leafy greens they grow include organic romaine, arugula, green leaf, green oak leaf, red leaf, butter, pak choi, sorrel, and spinach. The organic leafy greens are grown on reusable biodegradable Styrofoam boards that allow the plant roots to hang in the nutrient-rich water from the fish house. With the water pools under glass, Superior Fresh organic leafy greens grow from seedlings to full size faster than traditionally farmed lettuces. It takes between 35 and 37 days for a Superior Fresh romaine lettuce to grow to full size; on a traditional farm the same lettuce takes between 55 and 65 days to grow.
