Automatic Plant Watering System Capillary Mat Gardening Watering Tool Description: The capillary mat (also called absorbent cloth or extension mat) can distribute water evenly to the bottom of the plant container placed on it. This is a very easy way to maintain the condition of the seeds by properly moistening the medium when the seeds germinate, until the time required for sowing. All you need is a waterproof surface on which the absorbent cloth is placed and a container of water slightly smaller than the surface on which the capillary pad is located. For example, you can cover the counter with plastic to protect the counter, and then spread a pre-moistened absorbent cloth on the counter and hang a border under the sink. Fill the sink with water and put your seeds on it. As long as there is enough water in the sink that can be absorbed by the fabric (the hair pads should be in contact with water), they will remain wet. Get a distance of more than a few centimeters. I've been using it to pump water from the rain gutter, through the gaps in the plant gutter, and the gutter is on top of the mat. It keeps the gutter moist enough so that it has not irrigated more than the rainwater (also known as a rainwater ditch planting system).
