Ya know, I thought exactly this, until I noticed my entire harvest does seem to get much stronger as it slowly cures. I didn't believe it, but it's happened time and time again here.
I agree with you, there is a difference in cured and uncured bud's potency. While it is true that genetics are the
main determining factor in the strength of your bud, curing
does positively affect potency by allowing your final product reaches it's peak potency. That's a scienctific fact. Curing allows THC (certain non-psychoactive cannabinoids in it not all) that isn't active in wet or fast dried buds to change chemically to it's active form. I'm
not saying that ALL the THC isn't active in wet or fast dried buds, just certain cannabinoids.
Since I'm not in the mood to type it all out again, if you're interested in the chemical reaction that occurs, here is a post that I pasted same of the info into.
