What caught my eye in London...upside down eco chandelier

What: 'Sky planter Chandelier' 

an upside-down garden chandelier of real plants and aesthetic light bulbs

Made by: Boskke (plants) & Plumen (light bulbs)

Where seen: The Old Shoreditch Station Bar/Cafe (London)

This chandelier really is astonishing, knowing the plants growing upside down out of their sockets are actually real. A smart water-filter system in the plant's socket does the trick. The brand Boskke (bosky means a fledgling forest) improves conventional gardening tools and products for contemporary urban lifestyles. 

Although it looks really cool, is it practical and make it sense? Why would you want to hang a plant upside down, to pull a trick on Mother Nature? The designer of the Sky Planter pots with its patented water reservoir, Patrick Morris, argued it reduces the watering of household plants up to 80% this way. But another doubt rises: it is not unlikely some dirt will fall down. So, is it as clean as a normal downside up plant? 

All and all, executed as a chandelier with beautiful low energy bulbs I think its the perfect fit and make sense. As a loose pot hanging upside down, I have my doubts.
