Hypertufa for natural rock planters and slabs
 

I'm interested in producing hypertufa planters for bonsai. I've
talked it over with my partner in this and we don't want to imitate
bonsai pots ... more like make an artificial stone type planter, slab,
mountain etc. If any of you have any links you could throw at me,
that would be nice ... Ideas are welcome. I'll report back when i
have something to show.
