Cooling My 5x10 Grow Tent?

So I'm starting up a new grow with 3 1000 watt hps with cooled hoods. I have four 8 inch inline fans 720 cfm.
I have a separate room designated for this grow thats 15x15. My tent is 5x10x7 and I'm doing an auto flower grow of some candy cane most likely with 18 5 gallon pots. Anyways what would be recommend for cooling the tent the smartest way? i have a window and have been thinking about setting up a window ac unit for the whole room.

Window ac is great and easy....

Air cooled lights would help a lot and a/c is probably a must with 3x1000watts hps

You will need to air cool your lights and vent that air outside + use at least a 12000 btu ac window unit.

I had 2 x 1000w lights in the same space vented and a window ac and it was controllable. 3x1000 is going to be a bit of a challenge

Just got the 12000 btu ac and also plan on setting up the exhaust from the cool tubes running outside. I plan on using exhaust and intake in the tent as well to circulate and cool and have the ac unit just running for the whole room. Lets See how the test runs goes next weekend!

Would you consider running 2 1000w hps; and both cdl/cmh a 3100k & a 4200k in center
