The AutoPot 1 Pot XL Pot System comes supplied with a tray that accommodates a 25 litre pot and a Root Control Disc that is placed under the pot in the tray cavity with the gold side face up. The Root Control Disc or RCD will prevent roots from leaving the pot and discourage them from heading towards the AQUAvalve. You will also receive an AQUAvalve that controls the water supply and 1.5 metres of 4mm pipe that supplies the water to the system. The AutoPot 1 Pot XL 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 AQUAvalvue that has been designed to allow the plant to go through a wet and dry cycle. The AutoPot 1 Pot XL Pot System is easily extended so many pots can be linked to a single tank. The pots and tray can be easily moved at will meaning that if the plants grow too large they can be spaced further apart with ease. Once the system is set up and the tank is filled with water and liquid feed the system will take care of all your plant’s needs. All you need to do is remember to fill your tank from time to time.
