My post wasn't specifically for you per se, more of a general easy AF way to pasteurize and play.  Machines and moving parts (variables), not my cup of tea, but I hope you get it worked out MycoViking... I dig it.

For what it’s worth I agree with all the suggestions that the sub is going anaerobic post pasteurisation. I use 1 litre mason jars with filter patches and pasteurise in a water bath. 2 hours once core temp has been reached. When I tried this in bags with manure it went anaerobic quickly and smelled baaad if I didn’t allow oxygen in. My solution was borrowed, seal the bag and peg the top of the unrolled bag on a line so it pulled in oxygen through the filter patch.

The other solution I found is to avoid manure and use Faht’s recipe for sub. I’ve not had that go anaerobic ever.

Yeah, I'm probably gonna switch over to Fahtty subs... Does he have a link to his recipe, or is it buried somewhere in this thread?

I think you said you are using black Kow?  Personally, I never trusted that’s stuff, because it’s basically floor sweepings and mixed with urine and such (presuming they haven’t changed anything about the way they package it nowadays).  That would be my uneducated guess as to bacterial vectors. 

Not sure how easy it would be for you to gather some filed aged cow, and/or horse manure, however that’s what I would consider trying.

Edit to add: some bacteria can survive pasteurization.

Yeah, that's what I used... At this point I'd almost rather go with the non-manure substrates the other folks have good success with. I don't have a source for field-aged manure, so that would require making a new friend and I don't like doing that at my old age... You know, if it does have urine in it, that would explain the suspected low pH issue. Would worm castings be a good replacement for the manure, or Black Soldier Fly larva castings?

I live in farm-country too, but it's mostly corn and soybean. Not a lot of cattle where I live... Although... I think I do have a car show friend that has cows...

Do the fermenting/sour bags colonize at all? Manure based sub kept under somewhat low oxygen conditions does start to smell rank but it will go away with progressing colonization. This started to be discussed repeatedly when people were following Joc's advice of aging pasteurized sub for a few days to build up microbe count. Just thinking of this as a possibility as I don't see why your machine wouldn't work.

Eventually they will colonize a good portion of the blocks, but no full colonization. I usually spawn later the same day or the next after pasteurizing. After the temps drop to room temp of course. This is the last batch I spawned, and we're now a week after spawning and the grains still haven't recovered. Yet there is no molds or visible contams.

I'm sure Faht will chime in, he does CV+ and worm castings, damn reddit user.

Excellent. Thank you very much. Also, I had no idea that search bar was down there.

Neither did I until Baba Showed me lol

I've seen a lot of mentions about black kow throughout threads. Personally i use this stuff (below) and its been fantastic. I do CVG+ even though the G is pretty obsolete. For me it works every time. tek is in my signature and contains amazon links to all products used. I use the oven and meat thermometer for pasteurization and like Puff, I run ~150F for 2+ hours.

Its listed as manure compost, but its just manure, nothing else. Here is an Instagram comparison video between black kow and brut 

Just my baby 2 cents.

A few ziplocks.  This first one is one of the trays on the reptile heating pad… wrote about that Here. Super happy with how all the trays on it are doing.  There’s no indication that it’s drying the subs out at all.  Trays don’t feel light, fruits are cruising along np.  I think it’ll work well for the winter




This last tray I found some mold in the front corner pretty early on and broke off enough of the area that I salvaged a good portion of the flush

Only issue I have had with Black Cow is it contains a lot of sticks. This is easily remedied by sifting it through a piece of 1/4" hardware cloth.

50/50 Black Cow / coir worked great in my grows.

Jake, I was doing a little thinking (I know.  Dangerous, right?) and I think if you were to take your black kow manure and lay it out in the sun until it became dry on a tarp or sheet of plastic in the yard the urine and whatever else may be lurking in the bag would be evaporated away. 

Can’t say for sure if this would work, however it is what I do for manure that I’ve collected from stalls, and/or manure I’ve had to collect that wasn’t fully dry yet.  Just spitballing here.
