Why substrate instrad of grain ?

My skills are developing quickly. ATM I have healthy 100% colonized rye grain jars. Im getting ready to attempt a monotub something er other. I have Hpoo and straw... But ive been considering this a lot. I have seen mycelium colonize all sorts of things and fruit... Even produce decent fruit (although low yield) with little to no nutrients. So my question is... If mushrooms can grow and fruit just fine on say rye grain, why do we mix up fancy substrates like hpoo and straw or wood chips bran and gypsum ? My thought is mushrooms will do fine on grain but the substrates add a nutrient boost. Is that correct ?

For the most part, grain provides the nutrtion and bulk substrate provides sufficient water to expend the nutrients contained in said grains into mushrooms (90%+ water.) Poo and straw contain more nutrition but still not a great deal compared to the grains. Vermiculite has the least. There may also be some supliments contained in the bulk substrates.
Read this, I think you'll find it informative whether or not you want to use the tek: http://www.shroomery.org/forums/showflat.php/Number/18135103#18135103 Ooops, ^ Edited, wrong link.

I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister. I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave. I think it will be good cause B+ is so potent. Triggered yet? Only a square would say "a cube is a cube."
No, this does not look right...

the grains are the nutrition. straight grains don't do as well as grains mixed with substrate, cased grain does somewhat ok but not as well as a real bulk substrate with mixed grain spawn and sub.
before this was all figured out casing grain was a normal practice, before grain spawn itself was a normal practice people tried just inoculating substrate and that didn't work nearly as well using grain spawn does.

I've had pretty good luck casing straight grains, they can do Ok.
Lets say you have 4 quarts of rye and you case it, you might yeild a few ounces, which is fine. But by mixing it up with a bulk substrate, that same 4 oz might yeild 6-8oz first flush in a monotub

Thanks guys! That was interesting... I was on the right track but not entirely accurate.

You are Learning that's what matters...have you read the basics? This is how I stepped up to bulk.

It was my understanding that it was partly nutritious, but also provided more surface area for the myc to colonize. I dunno, maybe I'm wrong.

IMO given violet's results it cannot be that nutritious to cubensis. Other species are another story.
Also consider that the mycellium is growing massive ammounts to colonize the bulk sub, probably 2-4X as large. That requires a lot of energy and a lot of building materials.
