The Green man system can be converted and used as a flood and drain system. Using the substrate tray in the base of the pot, the pot can be filled with soil, coco or a subtrate mixture of your preference. This means you can have the best of both worlds, the efficiency and precision of the green man system with the stability and root insulation of growing in organic inert meda. 

This self-watering system features a Green man brain controller, a choice of combi pots, iceline pipe and a flexi tank reservoir. It is a simple system which can be adapted to your exact needs. It has a sloping base for maximum drainage and it is elevated to allow warm air to circulate the pot and in order to prevent it touching the cold floor. The pot itself is a generous 40L with a sizable root-zone capacity. Another useful component of the pot is the Airstone pocket inside which perfectly holds a 4" airstone in a stable position to reduce noise. The brain boasts a precision engineered grasslin timer to ensure accurate automation. The silent pumps connect securely to the brain unit with a unique connection socket.
