I’ve fucked around a bit lately with cold drying and curing and in my experience there are a couple of factors at play.
the most important thing is getting my fresh herbs to dry to the correct water content
next needs to be preservation of all the goodies that it contained when it was cut down, the terps that are present when harvested are in much higher volumes at this point, and the entourage effect will be stronger.
in my experience the colder the better, cold slows down terpene volatilisation
But also the less air movement and turbulence around the buds the better, as this strips away vital terps as well
and because it’s cold then it usually takes quite a long time to dry, like a month!
Im sure people will disagree and that’s fine (I’ve got no way of knowing and can’t get tests in U.K.) but in my personal opinion there is no need to cure it any further after this point. Everything good that could happen seems to have happened and it’s at that magic point where it hasn’t started to get any worse. This goes for it’s terps, it’s flavour, smoothness, perceived strength
