Alternative Spawn mechanics Question

So grains are nutritious and they are used as spawn. Why couldnt one use a mix of hpoo coir andor verm as spawn? What makes grains so good for spawning/inoculating, ive read that inoculating bulk with spores or LC will be slow and end up contaminated but i guess i want to know why lol. If its just a consistency issue couldnt you use verm to fluff up the hpoo and then inoculate?

paraphrasing what I believe to understand about this,
Grains are more nutritious than pasteurized bulk substrate, but pasteurized bulk substrate is better at retaining moisture than is grain, and since fruits will need both, we try and create a proper micro climate for their birth.
It all comes down to points of inoculation, in that once you have for instance a fully colonized wild bird seed jar, once you break that up into a pasteurized bulk tub of substrate, you are in effect introducing ten's of thousands of points of inoculation into said tub,
on the other hand if you simply applied spores to a bulk substrate, it would more than likely get over run with contaminants long before the mycelium would get a strong foot hold, The goal appears to be to give the mycelium a leg up against any potential competition / contaminants.

I wonder if you could pasteurize a substrate below field capacity and then use a assload of liquid culture to bring it to field capacity and then let it colonize haha. That' would be more work anyway but grains work great because we can smell them to see if they went bad they provide 100's of inoculation points as said above and then this allows us to get away with pasteurized substrate which is your only bet for working indoors.

Because those are less nutritious bulk substrate materials. We call them 'bulk substrate' because you use so much more of them. It would also be awfully hard to shake a colonized jar of manure or coir to use as spawn, but a jar of colonized grains will break right up to pour out.
The grains also provide the jumping off point to use as inoculation of your bulk substrate. We're not duplicating nature this way, we're improving on it. RR
