Two transverse ribs in spaced apart relationship interconnect the opposing margins along their length to seal the longitudinal seam, thereby forming a flow regulating tube defined by the ribs and the opposing margins and forming a supply tube defined at least in part by the remainder of the sheet. The hose has a plurality of longitudinally spaced inlets to the flow regulating tube and a plurality of longitudinally spaced outlets from the flow regulating tube displaced from the respective inlets to provide a substantial path length from each inlet to a respective outlet. | |
