HELP! 4 x 8 x 6.5 tent over heating like crazy!

How many degrees would one 16" wall mount fan cool the tent. I think 2 would be over kill.

I am pulling the air through the hoods and out of the tent. My basement is pretty big, and it's cool down there. I am using that air to cool the hoods just not working.

What I did today was swapped everything around. I had the air that was getting pulled through the lights going straight into a wall, now it's blowing to the basement. Turned both lights on and testing the temperature bottom of the tent. Will report back in a hour or so with temps.

Temps are now 29-30C. Not sure what else I can do. Maybe get a 16" oscillating wall mount fan and hope it drops the temp a few more degrees.

I use 2 6 inch inline fans from home depot to bring air into my 4x8 tents directly, . Mycarbon filter is in the tent and I use a 450 cfm fan to suck air through the filter and out the tent. I have 3 small 6inch clip on oscolatting fans to help move the air and then I put 1 house box fan at each end of the tent blowing into plants and eventually under.I run co2 so I run in cycles with sometimes no vent air out but always cool air in..I rarely hit above 82 ish when running co2. But on average with 3 open hoods with 600 watt bulbs I have zero issues keeping temps at that 78-80 mark F. Not sure why your having so much heat. 600 watters never seem to give off much heat for me. I run them open hoods in 4x4 tents to with less air movement.

These kind of show parts of how mine are usually set with plants in it with no heat issues or stress

Did anybody say a/c the outside if the tent to get the ambient temp down and Mabey add a small booster fan for intake
