The GrowBox container garden fits on patios and decks and features a cut-out planting guide that shows beginning gardeners exactly where and what to plant. The GrowBox then automatically adds the right amount of water and fertilizer. The entire system can be set-up in about 15 minutes. The heart of the GrowBox system is the patented Nutrient Patch cover that automatically adds fertilizer as the plants need it. Developed by commercial tomato farmers, the home gardener simply lays a Nutrient Patch on top of the soil and plants tomatoes, peppers, beans, salad greens or any other plants at the numbered slots. Inside the planter, a 4-gallon water well adds water at the correct rate so there’s no guessing about maintenance. The GrowBox planter comes complete with fertilizer, simple instructions and a planting guide.
