Boskke‘s Upside-Down Sky Planters is a hanging potted houseplant that sports a water reservoir and fixed soil to ensure that the plants grow down without any fuss. Other than being a great addition to our home, the system actually saves water usage up to 90% compared to conventional pots.  The Boskke Upside-Down Sky Planters are available in black or white, priced from $75 to $195.
