Thanks for the reply. I'm working with coir as a substrate for growing
Trichoderma sp. and it is working well. You can see some examples on my web
I think this is why coir is working so well though peatmoss grows similarly,
but as you indicated, I also see various other fungi growing (I don't yet
know what they are) on the peat that I don't see on the coir.
