Temperature

Difficult but there is solutions. Portable ac unit is expensize option. Window style ac unit can be used effectively if you cut a he used in the tent, the front in the tent with the back outside. Window style air Conditioners work differently in all the air cooled inside the tent is kept Inside the tent. The hot air ar back side creates co densation that can be caught, as a side benefit you will have 0ppm distilled if you run it through a filter. Ac unit will also dehumidifier slighlty as it cools. Win win. Causes irreprepairable damage to tent though, measure twice cut once.

I also have an 2x4 and my temprature is also about 29-31 C but i never had issues at these temperatures… you can turn you AC up if possible, but if your surroundings Are at 30 C than only a Climat controll will help
