Probably more than you ever wanted to know to about Perlite. As for
vermiculite, yes it breaks down (mechanically) into its clay like
components in about a year. It's not bad to use if you keep the
percentage low (under 5% by volume). It has a high CEC because it is
basically clay platelets.

Greetings,

I was speaking to a fellow Bonsai Enthusiast about Perlite and
Vermiculite. He says that Perlite is too white, and too light (so that
it floats), and that Vermiculite tends to turn to mush, though this is
only what He has heard about Vermiculite.

Could someone tell Me their experiences with these to mediums, as I'm
thinking of buying some to create a soil mix ... yes, I found a
supplier in Canada. lol.

Thanks in advance,
