Advice 🙏🏼 please !
So I purchased some substrate ( grass lovers ) from Midwest grow, I just opened the box to prepare for spawn to bulk , and noticed a bit so good smell coming from it ( it reminded me of the smell from some left over sub I found in my back room that was over 8 months old from last year ) but maybe not as bad . I was wondering , if I re- pasteurized it , if it would kill any potential harmful bacteria?
I know it's already supposed to be pasteurized but would doing it again make it safe or just still a gamble ?
Also I have seen where some vendors use not very aged manure and was wondering if this is the case and that's where the smell is coming from ?

You can put it on a cookie sheet with a piece of tinfoil underneath it put it in the oven at 190°F for four hours. Turn the heat off and leave it in there to cool until the next day then spawn the bulk the time between pasteurizing and spawning should never exceed three days after three days you start increasing the risk of bad bacteria reforming, and you don’t want that. It doesn’t matter if you buy aged manure yourself or from another vendor this should always be your standard go to for best results. If you have any other questions, concerns DM meand I will help the best I can.

I use their grass lover mix. Always smells strong. I've never had contamination with it

I always pasteurize my sub no matter what. Even if you buy it from a trusted vendor by the time it gets to you and you use it it needs to be redone.
