hight temp when lights out

hey guys. quick question. searched all over but no answer.
so my med is in 12/12 right now but due to high temps during the day, i've gone lights on at night and lights out during the day. grow closet in a dark area. the internal temps stay at around 80-85 during the human day and 79-83 during the human night time (when lights are one for flowering) ....
any negative affects when temps are in mid 80's when the plant's going through 'it's' night time?

Ya cause you need about a 10-15 temp drop for the night time.

Need more fresh cool air going into the closet.

Update. Highest it got was 93! Took a look over yesterday and she still looks alright. Definatley keeping some clones of this one. Looks like a very resilient strain.

Anything over 85 degrees and growth allmost stops. Not good for the flower cycle. You should do like dopdragon says and get some fresh air in there. Any extra circulation will help.

Thanks for the tips guys. I currently have a ranco etc hooked up to inline fans so Im definately getting tons of fresh air in there. Lately the weather has been good and Im getting consistent mid to high 70s. Hopefully my neck of the woods won't see 90s again for the rest of the year. I took her out the other day to do a mid cycle flush and she looked great! I'll have to post up some pics soon.
