Problems with my entire grow area

Hey Everybody,
I am having some serious issues with my climate and I would like to ask people that have more experience than I do with growing in general. My flower room is a 6'x8' tent my temps run 75-80 with humidity being at 55-60% from what I have gathered those numbers are not to far out of wack (on the high end of normal). I have 2 600W HPS for light I have a 6" exhaust fan with a 6" intake fan(not as powerful as the ezhaust fan). The main question that I would like answered is will those kind of numbers kill my yields or if i keep my res temps down should everything be ok? I am working on getting the temps and humidity down I am just waiting on money.

Temps not bad, watch canopy temp close to light.

No, your relative temp and humidity are in accurate range for cultivation. Keep your eyes on the height of your plants with your light, to prevent bleaching and/or burning of leaves. Also add CO2 to your grow room will help increase your yield. If you are going to add CO2 get a CO2 tank with a regulator. That's your best option.
