Found this excellent working aeroponics system explanation by a group of teens, Tribe Awesome , should be useful for any more newbies like me, http://tribeawesome.com/, still not sure whether V1 is aquaponics or aeroponics or both ???? think I'll be aiming for Aeroponics.
Just found another link from the NCBI in America, It's a research paper on the ' Design and construction of an inexpensive Home made Plant Growth Chamber ' . The chamber size is a lot bigger than OpenAG Bot but the principles are the same.Have yet to read the full report but it may have some interesting tips, like taking readings in Fahrenheit with their sensor because 1 degree F is 0.56 degrees Centigrade.
