But for those who lack land to actually grow food on, do-it-yourself ideas like windowfarming can be a revelation -- especially when all you have is some window sill space. Aimed at those who are looking to try out windowfarming, but are reluctant about spending hours building their own system, British product designer Philip Houiellebecq's conceptual hydroponic growing system Auxano offers the ease of similar DIY windowfarms -- and without relying on electricity and the guesswork involved with other systems we've featured previously like Urbio. © Philip Houiellebecq Made of recycled HDPE, steel and rubber, Auxano is designed as a slim, nested unit that can come apart easily, and can be arranged either vertically or horizontally. Plants and their roots are inserted into the removable top, which allows for easier harvesting. The roots are immersed in a nutrient solution that sits below in an insertable cup. © Philip Houiellebecq Instead of using electrical pumps to aerate the water in the system, the liquid is aerated through the use of a built-in, hand-operated mechanism at the unit's bottom that can be pushed a few times daily to ensure it doesn't stagnate. © Philip Houiellebecq © Philip Houiellebecq Though it admittedly may not have the green factor of 'doing-it-yourself' like a windowfarm made out of materials you find, this concept design nevertheless does eliminate the need for electricity, while also probably allowing people who don't have the patience to build their own to still reap the benefits of urban gardening.
