My dry rooms have always been cooler than 72F / 21C. Layed out on screens, with lots of air flow, dehumid set at 35% for two days, two days just on sreens, mix it around everyday. When the tiny buds can crumble (dry), I put in a thick contractrator garbage bag to bring the moisture out from the big stems into the buds. Usually for about 12 hours. Then back on the screens for a few if needed. When the medium stems are snapping they are ready to be bagged and sealed. If you let it 'sweat' in the black bags too long, it can ruin the smell.
Again, it all depends on how much you're working with, but everytime I do use a dehumid.
