Carefully change the water FREQUENTLY at first, I change every 4 hours for the first 2 days, and then let it run a couple more days with 1 water change a day. Don't use straight tap water, bottled water. Dry out thoroughly with air movement. You aren't going to be able to "cure" the bud, but treat it just like you would normal bud, give it a week in a jar after drying. Smell goes from swamp/grass to gone. The benefit is burning water-cured bud is pretty much tasteless and scentless. In with tobacco, the net effect is a lighter less strong smelling smoke, and, if you've aerated your filter, a really nice all-day buzz, as you smoke your "cigarettes." Unless you abuse the bud in the water, there's no change in potency from the cure (most cannabinoids are hydrophobic,) just makes stealth weed. If you break off trichs in the water, it'll weaken the potency.
