Without meaning to criticise the product in any way, I live in Oz &
have never heard of it. Since I'm no expert, that doesn't have to
mean much. But the membership of our orchid society includes
professionals, & there has never been any mention of it when potting
media were discussed. That's not to say the pros haven't heard of it,
of course, but nobody has cited it as being the answer to everyone's
prayers. The most common discussions centre on the relative merits of
peat/perlite mixes vs various bark grades & mixes. Further north
where it's warmer, mineral media like quincan & even blue metal come
into use.
I would guess that diatomite would have a high calcium content which
would resist acidification of the medium - provided the diatomite
isn't too alkaline for the good of the plants in the beginning?

Anyone here heard of, it or used it?

Their web page http://www.aussie-gold.com/ sure makes it sound like the
greatest thing to happen to orchids since sliced bread.

Any opinions?

Thanks,
