Best strain for hot weather??

I'm located in South America and have struggled over the last year with several grows. I've tried hydro (water temp always a problem) and soil. It's hard to believe, but my most successful grow was in an Aerogarden.
I have purchased an aquarium chiller and am also considering as an alternative, using a suggestion I read in this forum for using a foam ice chest with frozen water bottles to solve the water temp problem.
Because of heat from CFLs air temp ranges from 75 to 92 degrees. My grow area has plenty of ventilation (installed an 8" vent fan). Hot weather seems to be my biggest problem.
Is there a reccommended strain to grow in warmer climates?

i did diesel from dinafem in a desert climate with great results. huge fat calyxes clusters with little leaf material, excellent when it came to harvest time. kinda fruity overtones with the mom i picked and a heavy dankness
