How can I lower my temperature in my grow room without A/C. I’m currently using to clip fans an ac infinity inline fan and a tower fan and my temperature stays in the high eighties to mid nineties

Where does your Exhausted air dump into?
If it’s within the same room as the grow within it then you’re just recirculating already warm air.

you definitely need an ac but as a short term solution you can use dry ice. just google dry ice ac or something. i did and this popped up

you don’t need the canister mentioned in this design because the added co2 would be beneficial for your plants
but in the end you‘ll need a lot of dry ice in time with this method so get an ac

Where is your thermometer to test temps?
If it’s in direct view of an HPS then you could be monitoring the radiant heat.
you know when it’s hot outside and the temp is 85.
but if you put a thermometer in the direct sunlight it will bump up to over 100.

Where is the room taking air from and is it cooler than the ambient air in the grow? Is your fan moving enough cfm for the light it was intended to cool,

Without an ac unit, maybe you upsize your exhaust fan to remove more cfm. BTW welcome to RIU...

I have it on the inside of my tent but not in direct contact with light. I’m running a HLG 600 r inside a 4x4

I’m just using natural air inside my house without a ac my house is reading 81 degrees but my tent is reading 93 degrees. And I have my HLG 600 dimmed all the way down and I’m still seeing high temps.

Most the time you can only achieve between 5-10F difference in ambient temps when exhausting a grow.

I know you said to @jondamon the temp probe is not in the light, if the probe is at the canopy then it's catching the light/heat its that simple.
Put a shade/card tube over the temperature probe and check the difference.
If went by a open probe I'd never ever be below 26/27c,
Canopy temperature and air temperature are two different things.
What is the temperature at the air inlet?
