Hydro store Watering-Mats contain water storing polymer woven into a cloth for interior plants to reduce watering. Simply place your house plants on the mat and through capillary action, plants are watered for up to three weeks. Ul-trastore-Mats absorb similar to a spon-ge and hold it in the plant container. Non-toxic crystals are woven into the degradable cloth material. As the soil begins to dry, the mat slowly releases stored water to the soil and the plant\'s roots over an extended period of time. They reduce plant watering with less worry and save time and labour.
