The Good Ideas, Inc. Garden Wizard Raised Bed Garden is the most innovative raised bed on the market today. This raised bed uses four 50 in. wall sections that interlock to enclose a 4'x4'x10 in. space. And it is the very first raised bed garden that can water itself. That's right, this patented design makes use of a special soaker hose that connects to each wall. When you fill one wall with water, it transfers to each of the other walls while simultaneously watering the garden. The unique soaker hose uses a slow-drip, wicking action that only delivers water to the soil when needed. So you can be assured that plants will stay watered, but not over-watered. But the wall sections can also work without the soaker hose, providing you with a beautiful, sturdy, and inexpensive rock wall border. Now there's no need to purchase expensive bricks and spend hours installing them. Most raised bed gardens require a lot of set up time and effort to complete and use treated wood or other unsafe and easily damaged materials. The Garden Wizard RBG takes no more than 5 minutes from start to finish. Simply layout your setup location, connect the wall sections with the pins and attach your included soaker hose (optional). Each kit can be infinitely expanded. It's made in the USA using FDA approved Polyethylene.
