Does vermiculite really aid in breaking down organic materal in the soil?

So im trying to make a nice organic soil mix. Ive got a base soil of peat moss with perlite, worm castings, and possibly some coco coir and bat guano. My question is if i should add vermiculite.

I have heard that vermiculite is very good to have in organic soil because it aids in the organic chemistry of the soil. If i remember right, soil is either bacteria- or fungus-dominant and vermiculite helps it be more fungus-dominant, which marijuana thrives in.

Does this sound familiar to anyone? If not, what are the real reasons for vermiculite in a soil mix?
