The Autopot Easy2Grow system is extremely versatile and is suitable for a wide range of plant types and sizes. Seasonal flowering plants and evergreen shrubs thrive thanks to the unique AQUAvalve valve, which creates a wet and dry cycle for the plants. The Autopot Easy2Grow accessory box for 12 pots (Aquavalve5) contains all the necessary connecting materials, including 9mm and 16mm tubing with specific diameters.
