It all started with a simple wish to grow her own food in her tiny apartment. So Britta Riley and her friends developed a system for growing plants in discarded plastic bottles. Thus the Windowfarms Project was born. The project strives to combat global food shortage by helping urban dwellers to find a way to grow fresh food in their inner-city apartment.
Basically a windowfarm is a vertical hydroponic systems made of recycled bottles and other common household materials. It is used indoors to grow herbs and vegetables year round. They provide free instructions that help individuals build their own windowfarms. Then, these new windowfarmers contribute back to the project through testing, proposing, and sharing local innovations which improve the designs over time.
