I would just grow and deal with the heat. thats what I do with my Cab... and I get decent results.

My cab hits 90 during the day somtimes. And its an average of 82 to 85, For The Veg part of the Cab.

Don't put them too too close to the CFLs, Thats all I do YOu can see my results

CFL Grow Cab Log

I open the door when the light is on in the 12/12 chamber but it still sits around 80 or above on any given night.

Two things I do is One get fans blowing air like mad around in there. SO even if its hot air at least its alwasy moving.

And two get some good stress relief vitamins. Superthrive or somthing A little more geared to heat stress and such. I use a product called BIO-GENSIS Synergy and man I'm not sure if Its helping with the heat like it says it will but since I replaced Superthrive with it My plants look 1 million times better. Thicker more vigrous etc. All kinds of Pluses.

chekc out my Log... those plants were grown at high temps 80percent of the time I would say.

Just grow and except there aint much you can do about it for this grow. QWhen you get a new spot to grow, hopfully it will be better.
