Your temps are not bad off. 50percent humidity is what I go for,
I dry mine in big brown grocery bags, and if I had your conditions, it would take mine about 5-6 days. Before putting in jars, and start burping.
I was raised up hanging them, but that's when we grew alot of plants outdoors, and that works fine, but the bags make it lots easier ,at least for me .
Main thing you don't want to do is over dry them.
GoodLuck with your drying.
