The passage of the 2014 U.S. Farm Bill (Agricultural Act of 2014, Public Law 113-79) granted growers the opportunity to cultivate industrial hemp (Cannabis sativa) under university and state government research pilot programs. By 2019, over 1,000 growers representing approximately 9,700 ha (24,000 acres) participated in the program in Kentucky. Industrial hemp was grown outdoors in traditional fields for fiber and grain production. Hemp grown for cannabidiol (CBD) was raised in either fields or greenhouses. CBD cultivars continue to be the most widely grown type. In 2019, 92% of the acreage grown in Kentucky was intended for cannabinoid extraction ( html).
