I've never used the water curing method and I doubt I ever will. I just haven't seen or heard people doing it much but it is suppose to really flush out the chemicals in your plants. Here's a tutorial on it: https://www.rollitup.org/view.php?pg=faq&cmd=article&id=434
I just dry it the old fashion way. Hang the buds for a few days, trim and put them in a jar, open the jar every so often to let it dry some more til they're done.
There is a water cure..I've never tried it... but if you search type this in search at top of page fdd2blk cure, harvest you'll find a wealth of info... most do the jar cure........
