Herbow is a window planter ‘tray’ that enables people to grow small crops outside their windows while shielding their interior space from the rain. By swinging Herbow upwards, it becomes a window shelter that blocks the harsh sunlight and the rain. At the same time, the plants are watered and grow naturally. An eave has been designed to extend over the shelter to stop water falling through the gap between Herbow and the window frame. Holes on two sides of Herbow allow for drainage of excess water.
