> Oh, WE USED YOUR STUFF, BUT VERMICULITE SEEMED TO WORK BETTER THAN PERLITE IN THE OUTSIDE BED, MAYBE THE PERLITE HELD TOO MUCH WATER AS I WAS GETTING HUGE MUSHROOMS IN OUR BEDS!

I believe you have that backwards.
Perlite is almost hard. It's a bit like a white hard Rice Krispie, and often that size, but various shapes. It is mainly closed-cell and holds moisture on the pores in the surface.

Vermiculite is darker than white, tan or beige or grey, and sometimes shiny, like its source; mica. (Mica was once the natural element, flakes off in layers, used as electric toaser insulation inside, behind the heating wires.)

Vermiculite was used as attic insulation as well - BUT it was discovered to be a health hazard if the source was not pure enough. Agricultural vermiculite is safer. I'd even say, SAFE. Vermiculite is soft, and not cruncy like perlite. IT can hold most of its volume in water, if it has time to absorb it. This can be too much water for some, who may mix the two.

For Mittleider applications, follow the directions.
