That is a fantastic question. Does curing and natural decarb both happen as a result of oxidation? I don’t know the answer to that but if so neither will progress quickly in vacuum (assuming thinugs like UV light are excluded). I suspect it isn’t a hard vacuum with simple gear so it couldn’t stop it completely but it could slow both processes. This is all speculation, I don’t know for sure but it is an interesting topic. I think one good question is what exactly IS curing? The only thing I know is that people say it helps break down chlorophyll and possibly other undesirable plant compounds but is there something else to it? I would love to know from a scientific standpoint what happens with curing.
Short answer is I don’t know but I suspect it will cure more slowly. I also suspect that weed already cured will degrade more slowly. The downsides to vacuum storage from the article all seemed to be related to static pulling off trichomes, chemicals from some types of plastics getting into the weed (because the vacuum methods they addressed were all plastic film related as if it were food storage or sous-vide) and the trichomes getting broken off from the compression of the plastic film.
If you do learn anything more concrete I would be interested to hear more.
