I dry for 2 or 3 days but our relative humidity is very low most of the time so its quite fast.6 days sealed , unseal inspect and reseal after how long dry roughly? Mine are past the 6 day mark. Time to open up looks like.
In summer its too fast to dry and has to be regulated.
When trying it for the first time or even when trying new techniques you should not feel bad to constantly open and inspect the cure.
Take note of the changing aroma appearance and texture of the cob as it transforms.
I go by that method every time I can tell when its nearly there by the look and smell alone.
Short of doing a short course with a teacher the only way is experiment yourself, every plant is different with different methods used to cure it for best effect, aroma and taste.
Not everyone will get it right first time. Some gifted individuals excel straight away as its an art it takes practice.
It would be so nice to get together and compare each others work it would be paradise to me for sure.
