These pumps are the backbone of most hydroponic and aeroponic operations. They move water and nutrient solutions to the growing areas and back again. They also provide water pressure to operate misters and sprayers.
Without water pumps hydroponic operations would be completely manual. When attached to a timer controller or environmental controller these pumps will be activated periodically and will require very little human interaction. A high amount of automation in a hydroponics operation can be achieved with only one or two pumps.
Large numbers of plants or wide areas can be irrigated and fed with a single pump and no human labor. These pumps can be used for many other tasks and can be used to build custom watering systems.
