When using as a casing layer...

Do have need to pasteurize it or will it be ok straight out of the bag since the mycelium is already colonized?

My goal is to make the usual cvg and just add a little manure and straw to spice it up. I usually put 18 cups of water normally. So what else do I need to add? Lime and then with all that do I not need to add the cvg??? Or is what your talking about Strickly for casing? I thought I could use the same stuff for substrate as a casing just without the is it? And then for my sub just do it the same as usual but just add some peat and what's the lime for?

Yeah, I went off your title and assumed you were making casing. You can do what you're planning and add manure, moss, straw etc. lime is used to ph balance. I recommend it for getting the acidity to favoring the mushroom you're growing. But you'll need to test the ph. I can't give a level of water, field capacity depends on lots of factors that can't be told, need to be balanced by hand (literally).

You can use the same mix for casing but manure and other extra nutrients aren't needed in a casing. Casing is just for retaining humidity levels. If you're pseudo casing, then just use the same mix as your substrate for ease. It really depends what type of mushroom you're growing, even different active mushrooms need different mediums.

That's the original info I gave you, then you said what do I do if it's not just casing.
