How Does it Work
The ebb and flow mat is a bottom watering system which means that water is supplied to the base of the pot and moves up into the media. Sprinklers are top watering systems and so irrigation water moves down through the media and drains from the base of the pot.
Top watering systems leach fertilizers from the media increasing costs and causing environmental problems. With bottom watering, leaching only occurs when it rains.
The Ebb & flow mat has three layers - A base impermeable layer that contains the water and prevents drainage losses, a middle layer of geotextile that distributes the water and a top layer of ground mat that protects the geotextile from mechanical damage and algae and restricts evaporation . Water is supplied to the geotextile layer by drip irrigation lines in sleaves on both sides of the mat.
