Jeez you’re combative, but also sorta correct depending on if you want to get me! I was thinking of this post right here:
Where he dropped verm from 50% to 13% (i.e. “moved away from”). But I get it!
P.S. Amongst other things I’m a licensed asbestos project designer. (Hit me up if you need a design on the cheap, $70/hour). The factoid about asbestos is true for sure, not that it stops me from using it, and I still go for that version 1 blend @ 50% for that sweet CEC as you do.
…And since he’s using 12% rice hulls for Si, yet Wollastonite is where we now get our Si, I drop the rice hulls… don’t need them. They are just filler that that point. So, I substitute some perlite, I use 12% perlite. It turns out that Promix’s ready-made HP blend ends up being around 12% perlite when mixed with vermiculite. That’s alarmingly exactly what I need. I can just add verm, wollastonite and gyp. It already has the wetting agent, the lime, and also delicious mycorrhiza, it’s sterile and consistent, it’s so widely used it’s FRESH, it’s cheap too from my local Griffens. You should consider it.
In the end, the nature of peat as a media is the same between the two, and I mention promix because it’s the best, most-similar mix we have to point at, and they just so happen to offer tons of interesting articles, and learning modules on these topics.

I’ve seen this is other states… I bet they drop verm completely at some point. It’s not that “asbestos bad” it’s that vermiculite dust ends up rendering public facilities as asbestos contaiminated, and abatement is expensive. It’s purely administrative.
