With water curing you dry the bud, then submerge it in a tray full of water, get a plate or something to hold it down. Change the water everyday for 7-10 days and you'll end up with better tasting, more potent bud. You wont end with as much as you put in, but thats because the water has removed all the stuff you dont wanna be smoking. It makes it more pure, and therefore a smoother smoke
