A new twist on the macrame hangers of the 1970's, Boskke's Sky Planter is an upside down planter. (Much like the inverted tomato plant idea, I'm guessing.) It locks in the soil so there's no mess below, and because you water from the top down, there's no water lost to evaporation. Its 'internal reservoir system' means you water less often too. A conversation starter, no doubt, that will save precious floor space. Not bad! Via.
