New grower

So do you have an exhaust fan? (A fan to suck old stale hot air out?) Leaving the vents open to let in fresh air won't really happen unless there's air being sucked out. Also extra fan inside the tent will just blow around the old hot air.

Easiest fix, buy a decent, inexpensive exhaust fan and ducting, and suck that air out and get rid of it away from the tent, leaving vents open to get fresh air in. If that's not an option I have seen people rig up regular fans as exhaust fans but it's not ideal.
Thanks for reply, we I do have a carbon filter connected to the fan the one like in a picture. Filter I keep inside and fan outside the tent..
 
save all your old soda bottles and fill em with water and freeze em. if you were to put several into your tent at a time i bet it would bring down the temp a little.
In other types of growing people rely on ice to cool plants down. I think some people water orchids with ice cubes.
Last summer i decided to try something from the papaver family but it was too hot already for the seedlings. i got one to survive by keeping it cool with ice till it was strong enough to withstand the heat on its own.
Had done this one few years ago, but then I had a small tent and it really helped a lot
