s traditional Jar planter is made from a natural stone exterior, fiberglass material and comes in a stylish white plaster finish. It is sized to perfectly fit a 12" dia grow pot for drop-in of your plant of choice. It comes equipped with a shelf that raises the grow pot to the perfect height, if using as a cache pot. However, the shelf also has a self-watering design that allows this Jar planter to function as a self-watering planter if the live good is planted in potting soil. This planter is designed to only be used as a self-watering planter in a covered outdoor or indoor setting. If using outdoors, a drainage hole can be drilled with a standard drill bit to ensure proper drainage. This planter is lightweight, easy to move and is frost proof when not holding water.
