Hey parodias, ease up a little. I don't know of anyone here who is a expert, and as a "forum" anyone can express their opinion as to what they think a cactus might be. That is how a person learns.... snip Is it a matter of recognising primary plant characteristics or just a wild guessing ...

PS I found my tech bulletin which unfortunately is in Dutch giving physical and chemical composition and that claims that the basic clay is "German Westerwald Clay" This is also confirmed in this Czech hydroponics site "... Seramis is a porous substrate, that is expanded by heat from ...

I tried to emphasise that a lot of compositions go under the names of "Diatomaceous earth" the different types even have their own "geological" names. (see http://www.perma-guard.com/articles/All_DE_notthesame.html ) But a microscopic analysis may clear up if Seramis contains the...
