Pasteurizing Vermiculite Temp issue
    #2077427 - 11/06/03 04:52 PM (13 years, 4 months ago)

I was pasteurising some Verm. and i walked away for awhile. When i came back the temperature had risen to 190degress F. It was probably there for about a half hour. Is this too high for pasteurising? Am I going to get a Bacterial Bloom here?

If I'm not mistaken, you can sterilize strait verm with no problems.

So yeah, everything will be ok.

Its for casing though, so it will be exposed to air.

Your confusing casing material with substrate. Casing materials for the most part don't have any food sources for contams to eat on. They also don't have any naturally occuring "good" bacteria. So there's no reason not to sterilize it. On the other hand poo, straw, and other bulk substraits cannot be sterilize or they will become open to contams by killing all the microbs. The good, the bad, the ugly. You need the good critters to protect the substrate during the casing. So when it comes to verm, ( a casing material ) us high temps to kill everything for best results.

Ya see what I'm saying?
