Hi, Here is a good link on how to make them.
Hypertufa is a combination of concrete/peat moss/vermiculite to make a lightweight material used to form over/around molds to create planters and other containers. There are a few recipes found in web search. I have "planned" on making some for a few years. Now that I am "re-retired" I plan on getting some done. Good luck and be creative!
