seems that there's a little confusion about the difference between a cure and drying. Drying is simply removing moisture, rather boring really. Curing is less concerned with the actual moisture, and more concerned with the biological and enzymatic processes that continue after clipping and throughout a drying process. After clipping, buds are still alive, and can take more than 48 hours to 'die'. During this time the plant is not receiving nutrients, light, or anything, and will continue to biologically break down sugars and process carbon. The speed at which the plant matter actually dies depends on how quickly it loses moisture. Once dead, sugars will continue to break down in the presence of moisture (assuming there are complex sugars to be broken down, which there will be). Though the speed at which it dries will certainly effect the cure, it is the length of time which the drying took, as well as how evenly the drying was applied in this time that really define curing.
For instance, most growers hang dry for 4-10 days, till ~75%rh. They then jar, and 'burp' out roughly 1% per day (leave jars open for an hour or so). A target might be a finished rh of 55%, so a proper cure might be 4-10 days drying, then another 20 days of curing (burping), using 55%rh as a storage humidity. Hold properly cured bud up to something that was just left out for 14 days and quick dried, and they look rather similar (cured might look a little lighter, but might not be enough that you could tell), and have the same consistency. However take hits, and the quick dry will be 20% less potent, as well as make you hack your lung out when you take a hit, the proper cure is more potent, tastes like heaven, and the bong hits will wrap your lungs in pillowy goodness. Though with vaping the only thing I really notice is the potency (cured weed is more portent). I can take my headiest harvests, and I can take sugar trim, both taste the same when vaped, the only real difference I find is that it takes more of the sugar trim to do the trick than when I vape buds, so a vape of headies might be .3g, and a vape of sugar trim might take .4g.
I can clip a bud (or some sugar leaves for that matter), throw it in my iolite or in front of a heat gun, and vape it, the only real difference is that it takes a few min to dry out before it will actually produce usable vapor. The vaporizer will eventually dry it out though, then it will start producing vapor.
So yeah, cured weed will be more potent, but I think what you are really asking is how dry people get it before vaping. My experience has been the more dry the better, as far as milky hits and the ability to grind finely. I store at 55%rh, and most of what I smoke gets ground up at 55%, then left out for 1-2 days in a keif box till it is consumed (who knows what the rh is at this point, but I imagine it's a lot less than 55%
).
Hope this helps!
