Capillary matting allows the process of capillary watering to occur, which provides plants with water through the base of their containers, via the natural capillary action of the compost. The matting can be used with our staging trays to deliver water evenly over the whole area. When used with our Water Tub reservoir or our Big Drippa watering system plants can be kept watered for long periods. Matting can be used either way up; the dark grey side hides soil spills and attracts the sun's warmth in the cooler months; the white side will reflect more light, particularly beneficial for light sensitive plants in the height of summer.
