I stumbled across this fantastic project while on the FoodCycles website http://foodcycles.org . The Window Farms project is the brain child of tech-artists Britta Riley and Rebecca Bray and demonstrates how DIY urban food farming can be take advantage of all year round.
Their website http://www.windowfarms.org is fantastic and there are tons of great process photos and images from their exhibition at Eyebeam in NYC. They’ve also posted a very comprehensive design for window farms that you can build yourself at home. To learn how to build one yourself, step step-by-step, visit http://our.windowfarms.org/2009/07/30/how-to-build-a-reservoir-system-window-farm/ and download the How To instruction guide. Seeing as I have two large windows, six months of winter weather approaching, and a love for fresh arugula, I may just be taking this project on myself very soon.
