5 Gallon Buckets (Free-ish, ask your local Restaurants, I got 8 buckets that original had Pickles in them)
I also purchased a 3″ hole saw from Lowes to cut perfect circles from the of the 5-gallon lids, this is so the net pots will sit perfectly in the secured 5-gallon bucket lid.
That is all! Good luck!
