New 1200w set-up, help?

So i have a bed room for my working space, probably 8ftx12ftx10ft. I currently just finished my grow in a growlab120(4x4x7) tent, and am looking to upgrade. I purchased panda plastic and another 600 w set up to add to my current lighting. I also run a 400cfm inline fan with the scrubber blahblahblah. My question is if set up a "make-shift" tent using panda plastic within the bed room, say 6x6x10, will I need to get a stronger cfm inline to make up for the newly added 600w? or should i skip the hassles and get an A/C unit?

If anyone has any imput on this set-up or questions on how to make it more efficient that'd be awesome. My goal of all this is just to have more space for working around the plants, and obviously more light and heat control.

thanks!

Are you running are cooled hoods?

Yeah they're going to be aircooled hoods. I'm thinking that i really just need to either get a dayton blower and run a duct out of that into some wall or out the window. Or i need an AC unit. The bedroom window is on a street front though and 15 ft from the sidewalk, which makes me worry about security. But maybe insulation would cover that up in the right situation?

Anyone have ideas?
