When Rock Kietzer of Kietzer Farms built his first two greenhouses in 1981, his intentions were to produce enough tomato plug transplants for his own production needs. Within a year, however, the entrepreneur was also supplying neighboring growers and soon was on his way to becoming a major, regional vegetable and tobacco plug transplant supplier. Kietzer Farms is located in Sister Lakes, a resort community near Hartford, Mich.
