Can I bake dry verm?
    #1039408 - 11/09/02 08:38 PM (14 years, 30 days ago)

Hello, I though I read something about this a while ago but couldn't find it immediately in the FAQs or teks.. Does vermiculit melt or anything in the oven, I was gonna mix it with coco coir and bake to sterilization. Good idea?

Vermiculite is puffed mica, so you should be fine. However, verm+coir isn't a very good substrate... the coir will colonize quickly, but doesn't contain enough nutrients to support fruiting. Also, dry heat sterilization times are two to four times longer than steam sterilization due to poor thermal transfer. Finally, dry heat sterilization will dry out your substrate making it useless.

yeah, I don't think coir is really for nutrients anyway. And I've got a solution for dried out substrate: water! Thanks for the info, we'll see what happens

Yeah, I'd say go with brown rice flour instead.....I bake 'em both for about 20 minutes at 350 to clean 'em up a bit before mixing.

I'm a little confused, you are talking about baking verm to sterilize your casing layer, right? If so, don't use brf as ^ advised, but if you are talking about sterilizing substrate, don't bake it, put it in jars and boil or PC it. This thread is confusing.

You are correct. If he is making a casing instead of substrate then adding nutrients is just asking for contamination. However, in his post he refered to it as a substrate, so I assumed that is what he meant. Good catch.

The problem with adding water to fix the dry substrate is sterility. Unless under pressure, water will not heat up above its boiling point which isn't hot enough to kill most contamination. Invest in a pressure cooker if you have problems with contamination.
