a/c

I need to cool my room. As is it's about 85 in day time. The room is a 12x12 split into 2 halfs (green and bloom). I have 2 1000s and one 400 that is a/c and if I sealed my room and exhaust into attic I could drop a couple degrees (that's next with CO2). When summer comes I'm gonna be screwed.

I'm seeing 8000 10,000 and 13,000 BTU portable A/C units. Are these big enough for me?

My bloom room is 6x12 and grow is 6x12.


Thanks

I should add that the green half lingers at about 77 degrees. I DO have a poor route for my exhaust fan but can't fix until I get C02 cause fresh air is piped from the attic and exhaust into the living room.
