Growstuff is an online community of food gardeners. Using their open source platform, gardeners can track seeds they plant, exchange seeds with local gardeners, and learn more about growing their own food. Growstuff is in the process of developing an API that will allow 3rd party applications to be built around their open datasets regarding crop, climate, and geographic specific planting advice. The API will be in a JSON format with HTTP requests. Additional open developer documentation is available on GitHub.
