Need advise! Im growing in a Back room and worried about temperature...

I am growing in a back house room/garage and yesterday here in California it was 75 degrees. I will be just flowering in there so lights on 9pm off 9am..during the day they will be sleeping but the temp in room will probably get up to 85 degrees..is that ok for night time dark temps for my girls? I will probably have fans on to help but wooried about the hotter days..night time should be fine as long as I have adequate air flow...thanks in advance and any info would help out a fellow entrupenuer..

Mid 80s aren't great but it will do just fine my room hits 84 often with no Ill effects.. Ideally u would want it around 70-75 but mid 80s will b fine . Portable ac perhaps???
