It depends on how much you have drying at one time but when I had my grow in ffull swing, I was drying about a pound at a time. I built a cabinet that had shelves in it that were made with window screen. I cut my buds up into good size nuggets after trimming all the leaves off then placed them on a screen and placed in cabinet. The cabinet had holes in the bottom to let in air and a hole in the top with a computer fan connected to a timer.
When I had my cabinet full, I would turn on the fan continuous so that it would pull the moisture out of the cabinet slowly so as to not create a breeze on the buds. I usually let them set in the cabinet for 4-8 days, depending on the amount of bud and the level of ambient moisture in the atmosphere. But I could tell when the buds were ready to be jarred by gently squeezing a few of them. They would feel slightly soft inside but crispy on the outside.
At that point I would take them off the screens and put them in jars. Fill the jars about 3/4 full and close lid then place in dark space for 24hrs. Then go back and open jars and feel the buds. If the buds ffeel wet, I dump them out on the screens again and allow them to sit in air ffor a few hours, then put back in jars for 12hrs, then check again. Usually they would be fine at this point for airing them out every 12hrs for 1 week. Then air them every 24hrs for another week. Then air them out every 48hrs for another week. At that point they are ready ffor use but could be kept in jars and continue to be aired every 48hrs for another 1-3weeks for finer curing to really bring out the fflavors.
The key to knowing when to move to the next function is in feeling the buds for "crispiness" and inner "mushiness", then the buds should lose the "crispiness" on the outside while feeling more stiff or firm on the inside. By the 3rd week they should feel a little "leathery" on the outside but very stiff when squeezed.
Your buds looked to be small, "airy popcorn" buds rather than dense "nuggets". If those are the best of your yield then you are doing something wrong. Some strains will produce "acorn" buds or "golf ball" buds but the density and weight, and tightness of the buds is almost always a result of the amount of light that the plants receive while flowering. Yours look as if they didn't get enough lumens during their development and/or were subjected to continually high temperatures.
