Grow Journal of the Month: April 2017
Based on cigar humidor experience, the way to 'end' your cure is to let the essential oils dry out. At 55% RH this would probably take several months to 2 years to cause irreversable damage. In my opinion, 'well cured' and 'not good' are subjectiive. They are more criteria reflectiving personal preference than measurable, objective fact.
To answer more factually, I can neither confirm or deny that statement.
In my subjective experience, that does not seem to be true.
