That;s only for the pf tek where the dry vermiculite layer acts as the Gas Exchange filter. You would "sterilize" those jars. the vermiculute is the equivalent of the polyfil in quart jars.
so, I said all that to say this.
A bulk substrate doesn't need a protective layer. Just clean spawn mixed with some sort of coir mixture.
two different processes. also, maybe do some more research. things like

and then read the rest of his posts that he linked too.
good luck

majikProgramming said: Hey guys,
I'm about to put my spawn on bulk substrate (coir). However, I remember reading a while back (cannot find this again) that putting a layer of (dry?) vermiculate on top will help with contaminates (kinda like in a BRF).
I know that mature/strong mycelium can fight off mold and stuff but I thought this might help a little bit.
Any suggestions/advice with this?
Thanks!
That's not really necessary, I would add a thin layer of verm after spawning for 7 days or so, then re-colonize until the surfice is covered 30% with mycelium, then fruit it.
But, maybe adding it before the spawning phase might provide a better microclimate for pins..  Anyway, I would just go for it, and report back, as that would be a very interesting experiment

I mix my spawn with my substrate, then add a little more substrate on top to make sure there are no exposed grains. The idea is that if you allow grain to be exposed to air, it could dry out and render it more susceptible to contamination. The extra substrate on top prevents that. Should be to field capacity by the way.

You are probably referring to casing layers. A casing is a thin layer of non nutritive medium applied most often to fully colonized substrate to 'protect' it and give extra moisture for fruiting (it should not be dry). It also provides a microclimate that is beneficial to pin formation. Cubes by no means require a casing and lots of people swear by not casing but I almost always case. I fruit uncased monobuckets occasionally and the harvest weight is the same between buckets but the cased always produced more pins for me. (I don't have my buckets dialed in correctly yet although)

It might help protect it from airborne contaminants but I don't think the airborne sources after spawning are usually an issue in home cultivation, as much as people like to blame them.

It won't help anything. Sterility is never an issue with clean spawn and proper pasteurized substrate at proper moisture content with appropriate spawn ratios

As much as I love top layers or casing layers I now think adding them right after spawning is probably counter productive. If you look at the modern methods of commercial mushroom cultivation the spawn and the substrate are never touched directly. It's done that way because that's the major cause of cross-contamination. They use machines but you can pour the substrate and spawn into a clean container and just shake it up so you're not transferring crap from hands and everything you've happened to touch into your nice pasteurized substrate before it's gotten a chance to colonize.
