Thanks, I'll definitely keep that in mind! I have a friend who eats only organic for health reasons and to avoid ingesting the odd chemicals you mention, and he's definitely interested in an AutoMicroFarm.
There may be overlap with the market for food spectrometers, https://www.kickstarter.com/projects/903107259/scio-your-six... . You are providing food supply chain transparency at the point of production rather than consumption. This is related to software security efforts to build reproducible binaries from open source, to guarantee production integrity.
