Worth while question. As you've seen, I hang dry everything in my basement initially, then move everything to large tupperware containers that I open and close often each day until it's dry enough so it won't mold up if left closed. A lot depends on the outside temps, and whether the A/C or heat is running.
In the winter, with the heat running, obviously things dry quicker. I will normally hang to dry for around 5 days, then finish trimming everything off the larger stems, then move to the tupperware. It's a pretty quick process overall, much shorter than in the summer with the A/C on. In the summer, I usually hang for an extra day or two before the trim and tupperware burping begins. The A/C also cools the room, sometimes too much so I'll close the basement vents and often add a heater or dehumidifier to the area. There is also a slow blowing fan moving air around but not blowing directly on the buds.
I do not use any meters measuring humidity or dryness of the buds. I just go by feel and smoking it in a joint. If it burns well, it's generally done enough. The burping/curing process actually goes on for 1-2 weeks after it makes it to the tupperware. I might not check it as often as time goes by, but I continue to open and close things as I'm packaging things here and there.
And I don't like to over dry my stuff, as people will complain it dried out to quick after they get theirs. I like to leave a little bit more moisture in there than others, but just a bit more. So, lets say I normally start selling things about 12-13 days after harvest in the winter, and maybe 14-15 days in the summer. I also tend to include an extra gram or two to make up for any additional weight lost after people receive theirs.
There is no right or wrong way, as long as you dry in a darkened area, it's not too hot or cold (I like low 70's) and the fan(s) don't blow directly on the buds. I do a thorough inspection every day or two, looking for mold or other issues with a high powered flashlight and past that, just smoke a piece often to observe moisture and smokeability.
