one of my m8's is water curing one of his buds he says it should stay in water for a week and that will flush all the unwanted shit out from it, hes only doing one like this as a test to see if the reults are what he thought
i wouldent like to soak a bud in water personly but il have a taste when its done and then ill think about it lol
another curing method is to leave it in a airtight jar for atleast a month and will improve on the taste and high
cheers hope this helps
