A great low cost option that allows you to use your own pots, tray, water tank or container to create a complete self-watering system. The kit contains an AQUAvalve, connectors and 1.5m/5ft of 6mm/ ¼ in pipe, all you need is a container with at least 30ltr capacity and a tray with a minimum depth of 30mm. Many different sized and shaped pots can be held in one tray, allowing a large amount of plants to be watered together over a long period of time – a great solution to holiday watering.
