Water is essential for life, there's no denying it. On top of this, watering our plants is relaxing for many gardeners - it gives us a bit of time to forget about any other worries we might have, while we focus our attention on nature. While we all love our gardens, they shouldn't get in the way of the other things we enjoy, for example going on holidays. With a self-watering container, the plant can effectively water itself. This means that we can leave them alone for a few days while we enjoy some time away, and not have to worry about them drying up and dying. Capillary matting and trays are also great for growing plants and for starting seeds indoors, as they help keep the soil constantly moist, without overwatering.
