Automatically regulated, mechanical irrigation system in Cuba: A plastic bottle mounted on a metal frame is filled periodically with water from the tap, depending on the desired intensity of irrigation. The "rocker" with a counterweight tilts forward at a certain point due to the heavy bottle. The water from the bottle runs into an irrigation canal, until the rocker’s counterweight moves in the other direction and the process starts again. This automated system is particularly suitable for plants that require continuous irrigation.
