Have you had a chance to visit TXRX labs in Houston?
I was there about a month ago and met with a woman named Wanjun there who was very interested in the OpenAg project.
TXRX specializes in hacking old machinery to be used with Linux CNC. Their space was quite large and definitely seemed to be the sort of place perfect for a Food Computer and to find more #nerdfarmers. If you haven't had the chance to check out it I'd give it a look.
Also, Moonflower Farms was very interested in OpenAg, they currently grow Microgreens for the Houston area.
Lastly, Urban Harvest is a non-profit who may be able to help you contact other local farms in the area.
If you are interested in meeting with any of these organizations let me know and I can put you in contact with them.
