Please have my big THANK YOU for all information that You are posting here.

I'm just starting to work with hypertufa. Have made some simple pots and really like them. I plan to make some more big pots so I can use them for bigger plants and plant compositions. Wouldn't manage without all this information here.

I haven't seen any recipes here with using ceramsite instead or together with perlite or vermiculite in hypertufa recipes. Some people mention that they use some sand in all their recipes to make it stronger.

I've read ( at internet resources for builders not for hypertufa fans) that mixing ceramsite instead of sand into concrete makes it even more stable and strong. It's made of clay and process of making is similar as making perlite. And it is not heavy. And it goes in different sizes. You can have it (at least here, in Europe) as small as perlite. And it is not white as perlite, it's brown and goes absolutely unnoticeable in hypertufa mix. I put it in pot mixes and prefer to use ceramsite as a mulch instead of perlite because of it's neutral color. It really look nice.

Is there anybody who uses ceramsite for hypetufa? I might be wrong but it looks like ceramsite would be perfect alternative to use in hypertufa?
