An improved liquid level control device for improving growing conditions and efficient crop growth in a series of plant pots includes a first valve means, a connection means, and a second valve means. The first valve means is operable to control a liquid level in a first pot. The connection means is mounted to a portion of the first valve means. The connection means includes an inlet connectable to a liquid source and an outlet for directing liquid to a remote plant pot. The second valve means is slidably received within the connection means and is operably connected to the first valve means. The second valve means 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. |
