Drying problem

Hello everybody, I’m new here, I came from growdiaries.com. I have a problem and I want also your opinion. I live at 42° nord parallel, so is already very hot. In 2/3 weeks I have to harvest, and dry my babies.. the temperature in my grow box will goes from 26-29°C. I don’t have a basement, or better: I have it, but I have odor control problem in it, so is useful only if I have to put close jars. In my box I have a carbon filter connect to the extractor (outside the box) inside I have a little fan, and I also have another fan like the extractor to use if necessary. I can not use a fridge, my wife will kill me. I have also a mini portable A.C., basically an evaporative cooler. It downgrade temperature around 1 or 2°C but also increase RH. I know I have to stay down 60% RH. What’s your advice to dry at the best possible way may babies? I really appreciate your help.

P.s. I also have some boveda 58% RH ready to use

Research freezer curing. Dry for 4-5 days, keep fans running 24hr, reduce leaves prior to chop, then into fridge or frost free freezer. Maybe purchase a mini fridge.

Run an intake from your basement to your "box" and vent your exhaust outside. Maybe try running your portable AC next to the basement intake (after you run it) to pull more cooler air.
