Default of a 4 day dry on a cannatrol seems alarmingly fast.
I am in the camp of thought that a longer slower dry is much more important than any cure length. Obviously opinions on this one will wildly differ. The curing process is effectively a controlled decomposition, and decomposition only occurs when water is present. It’s oxidation, enzymatic, bacterial and all require water to break down the residual chlorophyll, sugars, etc. My thinking is the most progress on this process occurs when the buds are still wet and semi-wet, slowing as it achieves slightly too wet to smoke, and slowing to a crawl as it achieves smokable dryness.
