Drying when it’s roasting outside y

any tips on how to slow down the drying of my plants. I have 30degrees celcius coming in to drying chamber at times during the day when I normally aim for 18 to 20, there not chopped yet any ideas would be great. Ac not helping much gonna slow down the outtakes and keep an eye on humidity in cases it rises but I’m pretty sure there gonna dry too fast.

Don't refresh the air unless the temps or RH are climbing.
Hang em whole, roots and all. Pain in the arse trimming after but the more mass the longer they take to dry
