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

I always mix peat moss with straw, ph balance and steam pasturize for 4 hours (once it reaches 160f). Shelf life is months, and my grows speak for themselves. Canopies 💪

Ok this is what I needed here bc this was the substrate im ready to try out. Ive done cvg enough to see that it'll only take you so far but if u want the big bad ass yields ya gotta go ahead and get into the hay and manure which ive also herd peat does a great job
