) cultivars at a temperature 10 °F less than recommended (75/67 °F day/night) does not reduce crop quality for some cultivars, including ‘Freedom Red’. But, this reduction in temperature set points in the fall would reduce fuel usage for greenhouse growers. At

High tunnels are walk-in plastic-film-covered structures used to alter the crop environment. Growers use high tunnels for season extension and to enhance crop quality and yield ( Lamont, 2005 ). This increased crop quality and yield are reported in

High tunnels are used worldwide to protect crop quality under adverse weather conditions and to extend the production season of crops through climate enhancement ( Lamont, 2009 ; Zhao and Carey, 2009 ). Temperature modification under high tunnels

, yard trimmings/waste, and other agricultural wastes ( Roe, 2001 ). The impact of composted soil amendments on chemical parameters of crop quality, rather than simply on crop productivity, has received relatively little attention. Amending the soil with
