    How the Largest Greenhouse in the U.S. Is Using 90% Less Water to Grow Their Tomatoes | EatingWell

    Here are some excerpts from the article:

    The 60-acre structure is the largest greenhouse in the United States. And Webb says that it has the potential to resolve a plethora of crises facing agriculture today—from farm labor abuses and fertilizer runoff to the impact of climate change and an over-dependence on pesticides, along with environmentally taxing inputs, like water. He hopes that it will also revitalize the local economy.

    While facilities like AppHarvest's do require energy to power heaters and lights, they can produce as much as 30 times more yield per square foot than outdoor fields. Growing tomatoes hydroponically requires 90% less water (per tomato produced) and no herbicides, and operations can even introduce predatory insects to control any pests that do slip in, according to Gene Giacomelli, Ph.D., a professor of agriculture at the University of Arizona who studies greenhouses and other advanced growing systems. This greenhouse is also a controlled environment—so no matter what the climate is doing outside, the plants always have perfect growing conditions. AppHarvest even installed a closed-loop recycled-water system to keep any nutrient runoff out of Rowan County's waterways.
