What about softwood sawdust (as in kitty litter)
Or free sawdust received?
Wheat bran?
Oat groats grinded up into a powder
Gypsum

Do these need to be pressure cooked?

Adding colonized grain.

yea, u should PC anything with nutrients for wood lovers.

that soft pine i bet u could do the pellet TEK fi u don't add anything in to it.

for real sawdust, i always sterilize, even if no supplement, but i think others might pasteurize.

Hardwood pellets aren't considered "real sawdust"?
Sterilize meaning pouring boiling water over?
What's soft pine?

they have to go thru a heating and compression process in production.
it is real sawdust and has a binder in it (mycelium will eat it though)

thats why u can get away with boiling water.

real sawdust is raw and not clean, so i would hydrate it and sterilize in PC myself.  others might pasteurize in jars or bags i think….can't really recall or link any thread in particular, but i remember people pasteurizing shavings or mulch just as u would pasteurize poo.

if u add bran, you should sterilize in a PC.

the soft pine is the kitty litter stuff u mentioned.  i never used it, but would expect it to be the same as hardwood pellets.
