The universal drip irrigation connector kit works for both single and double drip line mulch and allows you to connect two beds together. Connect the Flora Flow Pressure Regulator (sold separately) to your garden hose and then connect the pressure regulator to the universal connector. The universal connector can then be connected to your single or double drip line mats. To connect two or more beds together (up to 6' apart), simply unscrew the end cap off of the connecter to attach another universal connector.
