The Hour Grass Living Wall Clock is an interesting concept as it helps you grow grass in a vertical manner on your wall, where it will be confined within a stainless steel and glass body frame. The grass will never be able to grow above the clock’s hands, since both hour and minute hands will pass over the patch of grass, keeping it trimmed always thanks to their sharpened edges. A watering basin is placed at the top right hand corner for easy access to keep your patch of grass nice and well-watered.
