Well I guess then a portable AC is out of the question then?

You could make the grow box into a vortex type and have a fart fan ( bathroom vent fan ) on the top and passive air in on the bottom is about all I can think of with that setup. You can add coal filter sandwich to deal with odor and just run the fan 24/7.
