MAX facts hydroponic news, tips and trivia Market Lighting Affects Nutrients Many people reach toward the back of the fresh-produce shelf to find the freshest salad greens with the latest expiration dates. But a study led by U.S. Department of Agriculture scientists may prompt consumers to instead look for packages that receive the greatest exposure to light—usually those found closest to the front. For the study, the researchers exposed spinach leaves to light similar to the 24 hour artificial fluorescent light received by spinach in packages located at the front of the display case. A second group was enclosed in two-layer-thick, brown-grocery-bag paper to represent the dark treatment. Light exposure resulted in a significant increase in levels of: • carotenoids • vitamins C, E, K • B9 or folate (Source: www.ars.usda.gov) Falklands Company Shows Viability of Hydroponics Business This year, Stanley Growers, based on the East Falkland Islands, celebrates their 25th year growing and marketing their hydroponic produce—predominantly fresh salad crops.

The novel system has a biomass boiler—that produces 400 kW power and is, to date, the largest in Spain—and 40 thermodynamic panels—employed for the first time in intensive greenhouse cultivation—that heat the crops’ roots.
