Hi, first of all welcome! I am not experienced in doing bulk grows but have read a lot about it.
You could look into cold water pasteurization for the straw, I believe they use hydrated lime for that - from what I have read using straw can be a big contamination risk in itself so it would be good to clean things up I guess.
You could also use coir+vermiculite - since they both have less contaminants present than straw for example - or just plain coco coir, seems to be working just fine for some people..

Hello, fellow mycologists been lurking a long time, but never had a bulk setup. Going to use 66 quart tubs. I have been trying to decide on a substrate that wont smell up the house. I've decided to go with coir and maybe do a rez effect tub but wanted to get more than one or two flushes. Would wheat straw and coir be an ok mix on its own or would I be missing something? Is there anything I can add to the substrate to help resist contam?
Pasteurizing substrate doesn't really smell bad IMO... I use hpoo substrates pretty exclusively and I have never taken umbrage to the smell... It smells earthy, that's about it...
Your house isn't going to start smelling like farts...

Hello Dimitri. So i have come to realize(In my experience) that less is more with bulk substrates. For 5qts of spawn. I use 1 brick of coir, 2 qts verm and pasteurize with 4 qts of boiling water in a 5 gallon bucket. Works wonders, its Damion5050 Coir Tek. Sometimes I will use gypsum depending on what kind of grains I will be using. It doesn't stink up the house at all. There is a faint earthy odor when you open to bucket to mix it or to spawn but that's about it. Good luck!
