#$%^&*AU2013201059A120130912.pdf#####An improved liquid level control device (1) for improving growing conditions and efficient crop growth in a series of plant pots including: a first valve means (2) for controlling the liquid level in a first plant pot; a connection means (4) mounted to a portion of the first valve means (2), the connection means (4) including an inlet connectable to a liquid source and an outlet for directing liquid to a remote plant pot, and a second valve means (5) slidably received within the connection means and operably connected to the first valve means (4), wherein the second valve means (5) is adapted to move between a first position allowing liquid communication between the inlet and outlet, and a second position substantially closing communication between the inlet and outlet depending on the liquid level within the first plant pot; and wherein when the liquid level within the first plant pot reaches a predetermined minimum level, liquid from the inlet urges movement of the second valve (5) to the first position within the connection means (4) to allow outflow of liquid, and wherein when the liquid level within the first plant pot reaches a predetermined maximum level, the first valve (2) urges the second valve (5) towards the second position within the connection means (4) to close the outlet; and wherein opening and closing the outlet of the connection means (4) being cyclical depending on the level of liquid in the first pot.
