Foaf is gonna use some coir for WBS rez-effect.
Does coir need to be pasturized or can he just
PC it?
Will straight coir be good or should he use 50/50
coir/verm?
Thanks in advance.

sterilize your coco always

pasturizing is only for bulk subs like straw, poo, and stuff like that

I pasteurize mine with great results, you really don't want to sterilize a bulk substrate like coir or manure by pressure cooking, if you were to be using it as a casing layer, then i would suggest sterilizing, by pressure cooking. SO pasteurize for the win. I've attatched my end results using pasteurized coir.

if you get the brick form
just wet it with boiling water-
it's already pretty sterile
after the manufacturing process.

I always sterilize coir and worm castings - works great and is a lot less trouble for me than Pasteurizing.

Also, Pasteurizing worm castings is almost impossible (unless you are shooting for a pillowcase full of mud).

DON'T sterilize peat or manure - doing so drastically increases your chances for contamination.

Sterilizing only works properly with coir/castings (in terms of bulk substrates or casings).

That is one of the reasons I prefer coir and worm castings; they work just fine sterilized. I find Pasteurizing to be a huge PITA.
