Abstract: A garden planter with integrated irrigation and lighting systems (100) includes a container (101) for holding plants and an irrigation tube (107) for supplying water to the interior of the container (101). A light (213) is positioned above the container (101) for providing illumination. One or more fastening tubes (105) are used for supporting the container (101) and supplying irrigation directly to the container or concealing the irrigating tube (107).

Abstract: Building materials of modules of at least one mortise and tenon and either a curvilinear side face or joinder of the modules at angles other than zero and ninety degrees. Lateral ends of the modules are flush with lateral ends of adjacent modules. Preferably, the modules are: (1) of a low density aggregate cementitious mix; and/or (2) have a hollow space extending from the mortise to the tenon and include a structural support member passing through the hollow space and a compression retainer securing the structural support member to the modules; and/or (3) have grooves circumscribing the modules and which are proximate corresponding grooves on modules placed on top or below. The modules are preferably sealed to one another with sealant placed in the grooves.
