Hi Martin,
I moved your request to the "search" section.... ;-)
I do not have that clone - PDN in the US used to have it (
https://www.plantdelights.com/products/a…-thailand-giant ), but not any more.
Maybe someone here in the forum might have it, let alone that I doubt that it grows so big under our conditions; maybe with extra assimilation light in winter...
I do not want to loose you here in the forum but you might have more luck in the international Facebook group; they have an extra "swap and sell" group as well (I am not at fb...); search for "facebook amorphophallus group" (it's the group with 8000+ members) and "facebook amorphophallus group swap and sell"
Good luck,
Bernhard.
