How often do you change your bong water?

You Vaporbong, Interesting
What kind of set up do you have? I have been wanting to go this way for awhile. I have an Extreme Q and really like it, but having moist vapor appeals to me.

Try it out with the Q...I use the Solo, so I imagine that with the q it's just going to be even better...

I use the Solo directly in my root lil sista but I'll be getting a gong adapter and the VXL Cloud is on my Xmas wish list hehe

I did it!! I found a nice little bubbler and hooked it up to the Extreme Q. Love it! Monster rips and no Cough. Ok a little cough some times.

I use to clean my bong everyday... until one day after cleaning it, it was still wet and slipped out of my stoned hands =[

when it starts turning yellow, stink, or sits for longer than a week.
when im using it alot i gotta change it every day or 2.
