My conditions are a little dry through the winter (~35%), so I expect increased times as summer comes, but this is what I do: Full manicure, hang until outside is crispy but stem still bendy, cut nuggets off of larger stem and jar (about 20-22hrs to this point). From there it's all touch and smell. I jostle the jar a bit to move the bud around and then crack it and inhale the first burst that comes out, the change of the smell as it cures helps me know when it's ready and the changing smell after dryness has occurred reminds me to go for long cures. I cut the sides off of some cereal boxes and I'll pour the buds out into them until the edges are again crispy when pinched (usually about 30-45 minutes in the beginning stages). This continues until the flavor of the strain starts to emerge over the 'earthy' smell of curing buds and the buds stop feeling spongy when pinched. By the time the buds only have to be out for about 7 minutes to achieve crispiness, I start just burping the jars as opposed to laying the buds out. When bending a bud between two fingers results in the bud snapping cleanly in the middle, then she's ready to rock. At that point I twist one up and smoke it at a regular pace: if she burns true then she's ready for you but if she goes out then back in the jar to sweat it out. I cure for as long as I can after that, just checking the smell periodically to make sure everything is good....but with blueberry and cheese you are using some really distinct smells, so that might help me.
This is of course only one way and probably the wrong way or the least efficient or otherwise stupid, but it works for me.
