Short term heat waves

Just started a grow and my temp are mostly ok, room between 72-76 and res between 65-70. I can't maintain ac for 24hours so I have to shut it down for 3 hours a day the times vary but it is during light on and off. As the ac is off the temps rise room to 81-85 and res is around 73-78. Would these short temp raise affect my grow?
