The AeroGarden Extra is a raised bed container gardening system designed for use by individuals with mobility, lower extremity, or neurological disabilities or arthritis or spinal cord injury. This system sits on a counter or table and can be used to grow lettuce, tomatoes, herbs, or flowers year round. The Aerogarden uses aeroponics, creating a controlled environmental chamber in which plant roots grow in humid, rainforest-like air instead of soil. The user drops in the dirt-free, pre-seeded Bio-Dome pods, and adds water and nutrient tablets. The system features a built-in plant lighting system and a computerized timer that indicates exactly when to add water and nutrients, then automatically adjusts nutrient delivery and water flow and turns the lights on and off. This model is twice as tall as the AeroGarden 7 (see separate entry) and offers 50 percent more light. Other features of this model include advanced growing technology that automatically adjusts lights and nutrient flow to each stage of the plant's growth, a 24-hour super grow light cycle, a deluxe trellis system that adjusts as plants grow, and a grow light replacement reminder. The system also includes one seed kit (choice of gourmet herbs, mega cherry tomatoes, or sweet bell peppers), three deluxe growing lights, and nutrient tablets. OPTIONS: Additional seed and growing options include customizable salad seed, flower seed and herb seed kits, grow anything kits, and custom tomato and pepper kit. Other seed kits include Thai peppers, Chinese cabbage, Jalapeno peppers, coleus, and more. Garden starter trays, replacement bulbs, nutrients, shears, and additional accessories are also available. DIMENSIONS (HxWxD): 34 x 18.5 x 10.5 inches. COLOR: Black.
