Advice on maintaining temperature?

Hi!

So today is the day that I'm supposed to.crack the bags but I noticed on the thermostat that it's reading 80°F and I have a heating mat set between 74-76°F

My bags are inoculated and laying in my SAB what are some things I can do to lower the temperature a little bit?

The SAB is laying in my closet but my room also has the only AC unit in my apartment.
