I love this idea. I would like to see OpenAg at more conferences related to CEA, and Indoor Agriculture, but I think you're absolutely correct in pointing out this opportunity as well. It is hard to find willing volunteers in this industry as the demand for talent is so high. I think there may be a much more willing (and technically capable) volunteer base in the open source community than the ag-tech community at this point.
Two weeks is a bit short to grow anything but microgreens, what you could do is bring seedlings with you at about 16 days, and by 25-30 days they'll be mature edible plants.
How are you currently involved in the Open Source community? Have you built a PFC?
Very interested and supportive of this idea!
