Top shelf harvest techniques

Looking for some advice on Drying and curing for top quality results. Any and all help is much appreciated. I do have a climate controlled indoor area for drying.

I have had several great grows but always seem to screw up when drying and curing. Mainly drying. Seem to always have the same results whether I hang entire plant or branches. I keep room around 60-70, dark, humidity ranges from 40-60. I do not have a dehumidifier or humidifier since my numbers are usually good. Any help is appreciated
