This tough, injection moulded tray has a number of valuable applications. It will easily accommodate a full sized grow bag and thereby considerably reduces the required frequency of watering. It is equally useful as a water reservoir tray for pots and seed trays. It will hold 5 of our Large Seed Trays (G17). A series of shallow horizontal ridges feature on the internal base of the tray which can aid drainage. Made from recycled polypropylene. Size Check: 117cm (46”) Long 40cm (16”) Wide 5cm (2”) High
