Raised bed watering system \"Hydro Cup\" - 4 watering stakes + 4 cups in a set Never let your raised bed go thirsty again! The principle of our \"Hydro Cup\" watering stake and cup set is as simple as it is ingenious. When the soil in the raised bed begins to dry, water is slowly released by diffusion. Our raised bed watering system has been specially developed to deliver just the right amount of water in a dosed and targeted manner to the plant root. Simply put the watering stake in the raised bed and attach it to the cup filled with water. The raised bed irrigation system \"Hydro Cup\" takes care of your plants so you can enjoy a carefree holiday. This raised bed watering system consists of a set of four \"Hydro Cup\" cups and four fitting watering stakes. Optionally available in a smaller set. Please note: The raised bed cups in the \"Hydro Cup\" - 4 + 4 set cannot be combined with the watering stakes \"Hydro Classic\" and \"Hydro Wine\".
