cooltubes, AC, drop 1 light.

You don't say how big your room is. Do you have intake lines running air into it? Cooltube will also help as well.

You have to get the hot air out or cool it with A/C unit so how big is intake hole and exhaust hole?

Run your lights at night...

15 10gallon pots so lot u got plenty of space to play with...........sounds like you need more exhuast for such a large room.....or maybe your exhaust isnt up high....idk, just guessing based off of info given
