Wood, screen, staple gun, screws, hinges, slide lock thingy, tub for water collection (tub sits UNDER tank, not in it). Use wood for the corners, top supports (including one or two going across to support hanging plants), and in a large grid across the bottom to support pots for plants. Staple guns are awesome for attaching screen cheaply (fold the screen, staple through the folded area, and repeat). Make sure to measure twice and cut once. It helps to draw everything out... many home improvement stores will cut the wood for you, just make sure you know the measurements!
