My tent is in the garage when ambient temps were still in the 90s. In order to grow then I had to introduce some AC. I found a good deal on a portable but I had to do some creative hacking to be able to put the AC outside of the tent.
I used an Inkbird to turn the AC on, and then the AC Infinity controller to taper the booster fan speed according to temp.
Edit to add: Watch your humidity with this method, the AC tends to dehumidify very quickly. I added a 2nd humidifer that came on whever the AC was running to compensate.
