Water tray \"Ultrastore M\" - Environmentally friendly plant care for up to 3 weeks The ideal solution for the holidays! \"Ultrastore M\" ensures the optimal watering of indoor plants during your absence: thanks to these water storage mats, plants are supplied with moisture for up to three weeks. Our water trays consist of water-storing polymers, which are processed into a fleece. This can be used to line flower baskets and planters. The product is easy to use and reduces water consumption by 50%. The \"Ultrastore\" water storage mats are also ideal for plant breeding. They work according to the sponge principle: the water is absorbed and kept inside the planter thanks to the non-toxic polymer crystals which are woven inside the biodegradable fleece. When the soil begins to dry, the mat releases the stored water into the soil and roots for an extended period of time. The water storage mats are ideal for planters, hanging flower baskets and potted plants, both indoors and outdoors. They last for several years and are environmentally friendly. Each package contains two water trays.
