I don't know about that whole "THC conversion" business. At what point does this begin and end? Sounds questionable.
Anyway, I have discovered a method that eliminates the need for curring - at least it has in my experience.
You harvest by first trimming all the major leaf foliage that lacks visible reson. Then you flush the plant in the dark for about a week. If you don't have a good way of doing this use a bucket with a flushing solution and an air stone and submerge the roots. IDK if this will work with cut stems - but it can't hurt to try.
After 5-7 days you remove the flushing plants and hang to dry. Waiting until a thick branch will snap is too long IMO but you definitely want a sharp fold with some snap feeling.
I would then place product into jars - if it is too wet the following day I would leave the jars open over night and try again till you get where you want to be. After that there should be no hay smell and you should be good to go.
I think with this method the flushing removes a lot of the chlorophyll and other undesirables which is what curring is supposed to break down, hence eliminating the need for curring. As for THC "converting" I'd be interested to see something less anecdotal. After all THC isn't even water soluble and is on the plant surface so I don't know why it would need time after drying to carry out this process. I could be wrong but I haven't heard any complaints with this new method.
