I use two buckets for budwashing unless I get PM, then I'll use a third with hydrogen peroxide. You can use two buckets, one with plain water (r/o if you have it), and then fill up a 5 gallon bucket with 4 gallons of water and put in 1/4 cup of lemon juice. I'll splash around in the lemon juice for about a minute, then lightly shake the buds above the bucket to get the immediate excess of water off. Then go to the regular bucket and do the same thing. Once you're done, hang your plants, and put a towel or something down below them to catch any dripping water.
