The AutoPot 1 Pot System is extremely versatile and can be used for a wide range of plant types and sizes. Seasonal flowering plants and perennial shrubs thrive and produce an abundance of blooms and foliage because of the unique action of the AQUAvalve that is designed to allow the plant to go through a wet and dry cycle. The AutoPot 1 Pot System is easily extended so many pots can be linked to a single tank. The pots and trays can be easily moved at will. So if the plants grow too large they can be spaced further apart with ease. Once set up and a water butt filled with water and liquid feed the system will completely take care of all your plants' needs. All you need to do is remember to fill up your tank from time to time.
