I have this bag of horse poo. It's several weeks old and hasn't contamed yet and I don't think it's about to any time soon.

I'm going to add several pints of fully colonized BRF to it.

So, why do I need to pasteurize the poo? It's not like it's going to contam on it's own so why can't I just put the spawn in and let it do its thing?

well one reason i can see would be to kill any bugs (gnats etc) that might be in the poo causing a nuisance. id like to hear what others say too..bump

edit: also youll be adding moisture to the poo and im sure there are plenty of mold spores ready to rock

because if you dont it will contaminate 100% for sure

I dont know how the poo is being stored and how wet it is, but if it is wet to field capacity it WILL contam I promise.

ok, playing devils advocate...

horse poo lies around in the field all season long getting wet from the rain etc. yet when we get ahold of it it's not overrun with trich etc.

has anyone here tried working with poo that hasn't been pasteurized? :mistrust:

foaf didnt pc his last jars, and only one got contaimed, out of 12, but it was straight from the bag, and not the field

That's because it's exposed to plenty of fresh air and sunlight. Once you put wet manure in a closed environment , it'll contaminate quickly. Trich doesn't thrive outdoors, but it sure loves rubbermaid tubs.

of course when you add spawn it's no longer just poo
you can get success but odds are against you,
expect to lose ~ 2 of 3.

best pasteurizer out there yet. i hooked mine to a rough neck rubbermaid container. thank you sandman & lazlo:bow:

OK, 'cause I'm stubburn and have to see it for myself I've decided to run a little experiment.

I decided to sacrafice one second flush TX cake and mix it with two parts unpasteurized hpoo that is at two drips field capacity.

Cased it with a very light layer of verm and placed in grow chamber. The TiT has a large window on the top and has a fish tank air pump running through a jar of water, 24/7.

I'll post pics as things develop.

yup, it caught a spot of trich :(

Another reason to pasturize manure is because its full of spores and mycelium. Species like Coprinus are almost guarenteed to be in horse manure.

You see lots of pics on here from under-pasturized poo showing "wild" mushrooms, and the person is saying " got my first fruits " ...

That could be dangerous if it was a poisonous mushroom that was growing in that manure and you did'nt know what to expect.
