Often called a capillary mat, this item is a common sight in large greenhouses where automatic watering is a necessity.
Just set your pots on top and this mat will absorb water from a container (or sink) to water plants through the drainage holes from the bottom up. Constant root growth is encouraged, as plants are never over- or under-watered.
An excellent way to water soil blocks or plants that don't like water on their leaves. Also a good way to keep your plants watered while you are away from home.
Measures 36" × 72". Comes with a plastic underlay.
