The Autopot 1Pot XL system is extremely versatile and is suitable for different plant types and sizes. Thanks to the AQUAvalve valve, seasonal flowering plants and evergreen shrubs can flower and thrive profusely as it allows a wet and dry cycle. The Autopot 1Pot XL accessory box for 24 pots (Aquavalve5) contains all the necessary connecting materials, including 9mm and 16mm tubing.
