That should be around 60-70C so I figured I could use it as a ‘semi-pasteurization’ (couldn’t hurt right). Proper pasteurization was just too much work for such a small quantity.
If one would like to get 'proper' flushes/results, one should do all steps properly IMHO.
Pasteurization happens at those temps if they are held at that temperature (measured from the center of the sub) for a minimum of 2hrs, but ideally much longer IMHO. It takes two hours at those temps to kill off the competitors, if one goes longer it further protects the substrate from contamination from future microbial competition.
I agree with following the steps but as I indicated, this was just a test to get my motions right. Even so, I was roughly following this tek which mentions:
At this point your coir can be used as a sub. The hot water, and steam has probably killed off anything malicious living in there. But this is not guaranteed. So here is your choice. You can either use the coir straight from the bucket, and spawn to your sub, or you can load it up in an oven bag and pressure cook it to make sure that it is sterile. I recommend PCing it, just for optimal success rates.
On a more personal note: I believe in trying your own stuff, seeing what does and doesn't work so you feel confident that you're not doing unnecessary work. Should this box fail miserably, then I'll feel a lot better about the time I have to spend on my pasteurization.
Longer pasteurization times allow for thermophillic bacteria to continue to reproduce and occupy more of the substrate with their extremely hardy endospores which helps protect the substrate from competitor spores.
You can read all about it here:
and I think I cover it here:
The links you mentioned are about poo right? I don't see coco coir mentioned anywhere. I believe I've read in multiple places that pasteurization is not really necessary for coco coir. Also that those bacteria are not present on coco coir (but I'm not very sure about that). Please correct me if I'm wrong though, I'm here to learn!
Edit: Searching also led me to this:
2nd Edit: I think this thread made me doubt the presence of the bacteria. Not real conclusive though.
