I read somewhere that the perfect "lights on" temp is 77.2...The same person said that THC production starts to slowly diminish at temps above 80 degrees without CO2,and much more noticeably at temps above 85 degrees...
Temps 90 degrees and above without heavy CO2 can be stressful enough to cause a plant to hermie and would also seriously affect the plants THC production...

The normal amount of CO2 in our outdoor atmosphere is 0.03-0.04% CO2...
