The Aqueduct 3D-printed modular planter by Evan Gant is a very interesting idea. It makes a lot of sense. Here is how designer describes it: “This modular system utilizes the connections between each planter as a method of transferring water from the top planter to the lower planters. Each plant is saturated with water on its way down the bottom planter empties out into a larger potted plant.” How smart is that? And it looks rather cute too. Available for purchase here.
