The one or more cover members (120) are couplable to the periphery (112) of the at least one base member for providing a hollow space (140), and the at least one channel is operable to receive at least one tubular member (160, 162) supported at a distance from the at least one base member. The at least one intermediate filter is arranged for dividing the hollow space into at least two segments (172, 174). The apparatus is optionally operable to provide irrigation of one or more plants growing therein from seawater supplied to a bottom region of the apparatus.
