Well if you didn't want a link, you should have used the search button and found your own lol. But whatever, i'm bored, and no ones really on this part of the boards anymore..

So anyways, 1oz of bud to 1 lb of butter is a good ratio to work with..its usually the one that people suggest in all the other budder threads..
And the water thing isnt neccesary, but i think some people do it just to control the temp a bit. The only difference is after the process is done and solidified, there will be water seperated frmo the budder which you discard.
