The growth of microorganisms in the nutrient solution of a circulating hydroponic system was suppressed by ultra-violet radiation. Applied for three hours daily (572 Jm('-2)h('-1)) throughout experiments in which tomato and corn were grown, it was effective in reducing the population of microorganisms from between 500-800.10('3) to 10-50.10('3) cells per ml.
