This Living Wall Planter includes a self-watering tank that makes maintenance easy! To install, simply attach the tank, plant the planter, then hang it up. Planters may be planted and replanted wherever convenient and simply brought to the installation area and quickly hung up without disrupting other planters. The Living Wall Planters breathe and allow excess moisture to evaporate or pass-through. The unique design eliminates the need for extra-drainage, even in heavy rainfall. Plants in the Living Wall Planter can air-prune and develop healthy root structure to prevent plants from becoming pot bound. Made from up to 100% recycled plastic (darkest colors are 100% recycled). Each planter is built with BPA-Free polyproplyene and is 100% recyclable.
