I currently have a 25x27 space for flowering (I have an upstairs second floor that will be used for veggie + cloning)

Instead of filling the entire 25x27 (8 foot high) space with 42 1000W lamps like I originally planned, I have decided to go a bit smaller for my first time and go with about 15-20 600w lamps instead.

My question is, if I plan on using 15-20 lamps in the 25x27 space (about 700sqft), should I split the room into two separate rooms? or keep the one large room (again, veggie and cloning will be upstairs).

With this smaller (in relation to my original ambitious plan) what kind of ventiliation and AC system should I be looking at.

Thanks again to everyone that can help!
