The item's measurements are deceiving due to the substantially narrower bottom section.  It's construction is also in question due to the extremely thin material from which this made.  It's not much thicker than the temporary pots you get at a garden center with a small plant.  It's lack of strength is apparent even to the manufacturer, since they include a flimsy snap in reinforcement for the center of the planter.  There's no way I would purchase this for anything over the current close out price.  That said, the shipping and tax put this over its value.  I'm going to use it as an outdoor starter.  No way I'd want anything more substantial in it.  Also the drainage tray us pretty much worthless.
