We needed a watering system for our raised beds and this is what we came up with. It works great! Everything we used will be linked here except the roofing screws which we had and the buckets. We bought ours at our local Rural King. Most any farm store will have food grade buckets, just be sure and ask that they are. We did buy some multiples of these items due to the number of beds we have.
After having it for awhile, something we would do differently next time is predrill the hole in the bucket before fastening down to the stand. A few of our buckets has small cracks from failure to do this.
