I would just go for pasteurizing everything. I have had way too many problems with sterilized casing mixes and no problems with pasteurized. Heat destroys the h2o2, so adding it before pressure cooking defeats the purpose. Pasteurize the manure and the casing material in an old pillowcase in a large pot at 140'-170' for and hour to an hour and a half. Stomp the water out of the bags and rehydrate as necessary with .1% h2o2 solution.That's my opinion.

SpaceFarmer, in my limited experience I have found the "texture" of cow poo to be important and related to colonisation speed. If the manure was pasteurised in the method you described I believe it would lose its form and take too long to colonise, however I am only guessing. Have you any experience with actual pasteurisation of manure in the manner as described or are you theorising as I am ? Has anyone else played around with sterilastion or pastereurisation of manure ? I have only used plain natural cow shit. In nature the mycelium grows in the plain cow shit, you could say that it has been designed to. I guess It would have some natural defense mechanisms against most bacteria in the unsterilised stuff. What concerns me if the manure is heated that either some nutrients, or bacteria that might help it grow would then not be available to the mycelium having been destroyed by heat, or am I talking drivel due to my ignorance on this subject ?

Spawn, I appreciate you bringing , what for me is an interesting topic, however I believe that you wouldnt have to go to all those different variables. Just one or to experiments on each. One with plain dung, the second with pasteurised, the third with sterilised. I really dont see the need to load casing into jars and pressure cook and so on. I use manure without casing, and to keep your experiments as meaningful as possible I would advise to take out any steps or process's that arent 100 % nescassary. Once you have determined whats what with the shit then you could go on to the next step of experimenting with casing on the colonised dung. I mean what I am trying to say here is that you dont want your hobby to be any more work than it has to be. If you can get your shrooms to grow without the extra steps of pasteurisation, or sterilisation by learning how the mycelium grows on the poo natuarally then you are going to save yourself a whole heap of work. Dont work for your shrooms, let your shrooms work for you !

Fried, I suppose you are right. Dung would turn to mud with my method, but it could be fluffed back up when mixing in the inoculant. Perhaps The Learner's phase II composter with the warm mist humidifier would be a better route to go for pasteurization. I understand that dung is a fairly selective substrate, so no pasturization might be the best bet. Why take the extra step if you don't have to?

i see that these 3 people are entertaining the idea of "cleaning" the dung with heat. thats all fine and well but it in itself seem like an extra step. one word on contams, i have put pf cakes outside that were perfectly clean all white and i noticed that they got hit with the green mold. but this did not affect the fruit. so long as you split the fruit down the middle and it looks ok i think their is no problems. have yall seen soil after its been hit with a tiller, or a "garden claw"? it airy and light, why not take dried poo and till it like garden soil and throw in some pf cakes then. this is what i think will work. why change nature more than absolutly necessery. example the everglades in the 50's
