The Venetian Vertical Garden is a stacking, vertical planter. Each planter can hold about 2 gallons of growing media and thanks to its circular construction, can showcase plants and vegetation on all sides. This is especially useful for controlling the amount of sun or shade received by certain plants by strategically positioning the planter around the home or among foliage. The pods can also be stacked as many as desired (max 6 recommended) or used as individual planters around an area. When stacked in an offset fashion, there's plenty of vertical growing space, allowing taller plants to grow up between the pods without being hindered. Each pod is made from polyethylene, a naturally inert and incredibly strong material that's weatherproof and natureproof. There are also several drain holes that allow moisture to escape to avoid root rot. Made in the USA with several color options.
