it really depends on strain, and yield you are wanting to get. And don't say "as much as possible", set a real goal. You need some numbers to go off of to determine what exactly you're going to need to accomplish your minimum goal.

You could get a hell of a harvest out of that space with just 1 of those rooms alone. and some light movers.

Again it just depends on what your minimum goals are. So tell us what you're trying to achieve and we can give you better feed back.
