Central Lakes College student Sheryl Delaney-Smith prunes basil plants Tuesday, Feb. 23, in the hydroponic sustainable greenhouse on campus. The nutrients for the plants are derived from a circulating water system which removes waste from farmed fish and circulates through the plants without the benefit of soil. The horticulture class members are preparing seed flats in anticipation of the annual CLC Horticulture Department plant sale scheduled for May. 6. Steve Kohls / Brainerd Dispatch
