If you want to figure out how to water cure properly you should check out the grow faq. There is section about water curing specifically and it is described in detail. Its interesting, because you get a better THC to bud ratio when you water cure because it decreases the yield but not the THC content. So if you have 15% THC you end up with like 20%. It's also much smoother of a smoke and it is a basically odorless way of curing, which is a definent plus for people who are being extra discreet. Have fun and good luck!
