If you want to grow your own plants, you don't need your own garden. You can also grow your own flowering plants, vegetables or herbs on your balcony or roof terrace: "Urban Gardening" is the concept. All you need is a planter box, edding acrylic spray paint and permanent markers, and our instructions in which we explain each step. If you use an old discarded crate, you're doing something good for the environment at the same time. The spray paint has a very high opacity, a short drying time and is perfect for creating all kinds of objects, whether they are used outdoors or indoors.
