I'm definately NOT an authority on hydro, so can't be of much help on that end, BUT, I do know and understand basic growing needs.
First off, a 10x10 room is going to require about 5 1k lights to efficiently light it. Unless you have plans to build walls to section it off for seperate chambers.
An AC unit for cooling, but what do you have in mind for "flow through" ventilation? All chambers should have flowing ventilation that replaces the air at least 2-3 times per minute.
Any thoughts on the elimination of odor?
