Imagine living with a lush garden that is not only large but has an installed hose or sprinkler system that waters everything automatically. While it is possible to put sprinklers on a hose, the hose has to be manually turned on and off. It is meant for the amount of water that is appropriate for growing grass, whose roots exist at the surface and can stand a little drought. Something more sophisticated, like a garden irrigation controller, can serve bigger plants with deeper roots.
The controller works with the flow of water in a hose system. It controls the rate according to the level of output and how far jets have to spray. If properly set, it gets the job done while also saturating the dirt to a deeper level. It is appropriate for gardens and gardeners who are not fond of drip irrigation. It can be set for the early morning in order to avoid evaporation.
