Nah. The mycelium becomes one organism feeding on the entire substrate.

Yeah I know but I was thinking of a (future) substrate of coir/pea straw the pea straw would bring nitrogen which the coir lacks. So the sub would be coir and straw. Not sure what the requirements are for cubes, but they must require at least some nitrogen.

Also, for some other species like Pleurotus eryngii, that can really suck the substrate dry of both water and everything else...

What's your spawn rate? Commercial growing that using supplemted nitrogen at 2 percent, also uses a 1:50 spawn rate. Most often we're using from 1:2 up to 1:4. The spawn is the fertilizer. No extra nitrogen needed. Too much increases the risk of contamination.

Yeah I know the grain has quite a lot of nitrogen... I was probably just thinking too much lol.

Of course, I can't find the chart now. I had a reference for nitrogen content of grains. Can't find it now, but it was way higher than manure.

Oats (and wheat I think) are generally 17% protein. And proteins are (average) 16% nitrogen. All by weight. so 2.72% N by weight.
