In this world a secret society "farms" people with desired features (personality appearances etc.). They have ectogenesis of course; but they can't afford personnel to take care of the "products" until they reach maturity (14-20 years depending on the end uses). What kind of machines/software are needed to raise them in an appropriate way?

Consider that these people will be reintroduced into an already existing society and therefore need not be capable to form a new one on their own. In particular they need at the very least: language, self-care, basic knowledge of science/literature, basic social skills. 

I know this is a common tech in works that feature embryo space colonization but I am not aware of any that describe the technology in any useful details.
