What type of cooling technology should I buy - throwing money on the problem. How do I cool the room my tent is in

IMHO only a good AC unit capable to cool down entire home division where the grown tent is will help.

it depends on the space you have in the growroom. If you have space enough you can put an AC inside with a tube to connect outdoor. If yu don't have space, you should cooling the external environment in order to keep a right temperature inside, using an efficient ari flow system. Have a nice grow ! 💪

I run a sharp portable air conditioner it has dehumidifier, air conditioning,fan,and vent I use it inside my 4'x4'x80" tent and it keeps it at a cool 70°f to 80°f when it is over 100° f outside the tent ..... They run about 0 to up to 0 but well worth it......

Umm, are asking if AC units exist? It uses a condenser. You need to pipe the hot exhaust air out of the area one way or another - a window unit takes care of this for you. It'll reduce humidity too, so you may want to keep that evaporative cooler handy -- evaporative coolers are humidifiers by another name.
