How to lower temperature in a grow tent?

hi everyone, i have a 3.5x3.5 tent in a windowless den that is is open to the rest of the house from one side and doesn’t have any doors, the temperature inside the house and den never goes above 23 but in the tent i have been struggling to push down the tempts under 27. Cannot afford an ac unit atm, what would you guys do?

What kind of lights and exhaust you using? My tent runs maybe 3C-4C above room temp with a cheap 4" exhaust running when the lights are on this time of year. Clunky lights too. I've found the humidity is perfect when running just a few degrees above the room temp and humidity, ~20C and 60%, with the current fall temps. Summer time I had to run a fan on a temp controller though set at 29C but the fan cycled on and off.

With my intake flap open and exhaust running on low, temps in the tent are the same as the room it is in. I actually would like it to be warmer
27c isnt too hot, and definitely not hot enough to be considering ac. Your plants will do fine at that temp

Yeah, that's actually a good prime temperature.

Run your lights on at night when it's cool.

Why you blowing hot air down with that fan. Blow hot air up and out

27c ain't gonna hurt anything.
