Indoors? How does it vary so much? Do you run your lights during the daytime when the sun is out?

The bottom number (75) is fine. 100*F is very hot...too hot. You need ventilation. Direct ventilation from the light source accompanied by a fan blowing across the tops of the plants and a proper intake of fresh (preferably cool) air would most likely level out temps like that. The highest you should really EVER get is 85*F. After that, you are really risking hermies and even worse...fluffy buds!
