Hydroponics can rapidly help serve unmet demands for fresh organic vegetables, grown close to their market.  Though limited by volume, growing food in hydroponic greenhouses has many advantages. Because the greenhouse's temperature and inputs can be precisely controlled, plants grow faster and face fewer diseases than their counter-parts outside in soil. A closed-loop irrigation system results in major water savings and uses less fertilizer, while not introducing pollutants into groundwater and soil. These greenhouses can be adapted to many different crops, and facilitate ease of rotation, which enable the farmers to more quickly react to changing consumer demand. Finally, growing hydroponic vegetables closer to consumers will help reverse the trend of foreign produce imports and transporting food across the oceans.
