LIQUID MANURE PASTEURIZATION FOR COIR-MANURE BASED SUBSTRATES
This is a method to prepare yourself a lot of manure/coir based substrate with ease. Most of the time when you hear about manure based substrates you will hear the term "Field Aged Manure" which seems like some people like to believe is the holy grail of poop and an absolute requirement to successfully use manure in a grow. Well, like other thing in this hobby, this is not wrong but isn't the end of the story either. If you want to grow with manure then you don't have to field age or leach it. The only thing that is necessary to take care of is to let the manure sit in a bucket or bag for as long as it takes to loose it's pungent ammonia smell. This can take a few weeks but the good thing is you don't have to do any of the hard work like spreading it out on a trap or similar, repeatedly spraying or turning it regularly. Keep it in a bucket, maybe put a cloth over it to keep the flies out and that's it. Once the manure has lost its smell it is ready to use.
I grow a lot with coir / manure mixes cause I do mostly grow Panaeolus and I can't be bothered to properly field age my stuff so I only make sure the manure "smells good". I used to pasteurized manure in a sous vide cooker and the coir would get prepped separately with the Bucket-TEK. This works out OK except that this does restrict the amount I can do at once due to the size out the sous vide cooker. Also mixing the manure and coir together homogeneously is always a bit of an effort due to the texture of the manure and it takes too long for my taste. This is why I came up with liquefying the manure for the pasteurization process which has a number of advantages:
- The manure is dissolved in a liquid which makes it easy to bring everything to pasteurization temperature at the same time. No waiting for the core of the manure to get up to temp, this means it takes much less time and care.
- Large portions of the manure will not get partially sterilized.
- Since the manure is in liquid form it can directly be used to hydrate coir which reduces the effort to thoroughly mixing everything together.
- This can easily be used to make a large amount of substrate at once.
Now this sounds all good and some of you might think heating liquid poop will stink up the house but if you let it sit for a few weeks it will just be like cooking up a bunch of dirt and if this is not to your liking then there is always the garage to do the do or going back to growing cubes with just coir . So if you think that this might be what you were looking for then get yourself a bag of manure and let it sit in your shed for a couple of month or till ready. But do it now.
I'm doing this with horse manure and this is how I go about it:
This is what the manure that I keep around looks like. Just like some fresh horse droppings but minus the smell. I think this stuff is about 5 month old now.

I take out a few hand full and throw it into an old pot with some water in it. As you can see there are some worms in there so make sure you check the manure for those lanky diggers and get rid of them as much as you can. They are good for the garden so that is where they go. There is not a measured ratio that I use and if you ask me to take a guess I'd say that it ends up at a ratio of around 1:3 manure to water by volume.

I mix up / dissolve the manure in the pot with a small mixer attachment for a drill. Make sure to do that in a big bucket or at low revs or else you are going to paint the walls brown.

Once the mix is ready I put a lid on and put the pot on the burner. The target temperature is 140F, a little bit higher doesn't hurt. 150F is my absolute maximum. If I overshoot the temperature then I let the mix cool down to pasteurization temp and throw in a handful of fresh manure and all is good. It's so easy to correct this with a liquid medium. Since there are some solids in the mix that will settle to the bottom of the pot it is a good idea to give things a stir occasionally. This will prevent the build up of heat pockets under the sediment at the bottom and keeps stuff from burning.

As soon as the temperature is reached I switch off the burner, take off the pot and make sure the temp doesn't go below 130F in the next hour. What I do when using the electric element is I switch it off when the thermometer reads 130F. The temp will clime to just above 140F and the heat left in the element will keep the temperature for long enough. When using the gas burner I turn it off when reaching 140F and turn it back on when the temperature drops below 130F. I do have a hunch that it is not necessary to wait a full hour and one could probably get away with a shorter wait but I really don't have the time to test this out at the moment.

Once the manure was kept at temperature for an hour use it still hot to hydrate the coir. I take care to break up the coir brick into small pieces cause the liquid manure is more viscous than just water and will need to be stirred and mixed with the coir for a little while. It is better to pasteurize a bit more liquid manure than what you actually need and pour enough to get to field capacity than trying to make the exact right amount. Put the lid on tight and let things cool. Once cool you can give it a final mix and check if field capacity as been achieved before you spawn. Adjust with vermiculite if it is too wet or add more pulverized coir or squeeze out excess water. If it is too dry then add some more of the liquid or tap water. Soon enough you will get the hang of it. This will give a manure content of approximately 20% I think, never really calculated it though.

There you have it, the easiest and fastest way to make a lot of manure coir substrate 
Here are few photos where this substrate had been used.

1.33333 quarts of manure to 4 quarts water hydrates a full brick or 1.33333 quarts manure to 4.5 quarts water and 2 quarts of verm would be the recipe? Do i have that math correct? Id assume you might need more water than the standard 4 quarts considering you added manure thats also taking some water from the coir.
What is your exact recipe for the mono you use for 27 and 30 gallon totes?

Sorry mate, I don't have a recipe. Just eyeballing the liquefied manure each time and then pouring as much over the coir as I think it needs. When it's too wet I add verm and when its too dry I add more of the liquid cause I usually have some left over. Different coir and manure will have different properties so it doesn't really makes sense to give a recipe with exact numbers. I also try to use as few jugs and vessels as possible to spare me the cleanup so it's all done by putting directly into and pouring straight out of the pot.
Edit: if you like a few numbers then I can give you this: 1 brick of coir. ~3.5 liters of water, 3-4 good hand full of horse manure with a moisture content as if it came straight from the horses gut.
For the tubs I spawn one quart of grain in a ratio of around 1:2 to 1:2.5 for the smaller tubs and 1:2.5 to 1:3 for the bigger tubs. This comes to 3 to 4 quart depending on tub size plus a little bit for the top layer.

Ok i need to do some testing then. I see you add verm to reach field capacity. Thats an important step i missed. I am interested in the 15 minute pasteurization. Please update us with your findings when you find out either way

I have added some ballpark figures to my last post. Not sure if it helps though.
Will definitely test this to the extreme at some stage but at the moment I will play it safe to get some more results.

When you turn off the burner how high does the temp rise from 140? Usually 150 max?

When using the electric element I take the pot off the hot plate when reaching 140F and it won't climb any further. I assume you could switch it off at 130 and it would rise to 140-150 when you leave the pot on but haven't dialed that in yet. EDIT: the switch off at 130F is what I do most of the time now and temp climbs up to just over 140F with the pot/element combo I use.

Yea i think cronicr had a post on pasteurization where he left it and the heat rises using jars of peat with a thermometer. Good info.

Yeah he has a video where he does bags in a big pot.

He also keeps his manure in buckets IIRC.

Thanks for your work Baba
Will attempt at some point... still working up the agar for the species relevant to a manure tek
Will let you know how it went when the time comes

Sicko! This is my style as well. Liquid shit mixed into coir 
If I'm over capacity maybe hay or verm whatever is on hand. Substrates are more feel for me at this point.

99.99 used the bagged steer manure blend from homeD, see quoted post below. I doubt that this is something you could use with this method here, use it prepped with normal pasteurization or it seems you can use the steer compost straight out of the bag as said in the quote below. Worth a shot.

might work for manure? I have a feeling it's a no, but I can always just give it a shot and post up the results here for later if you guys think it's worth a try. These are the closest to cow manure I can actually buy from a store. Doesn't look like any stores online will ship here either. Anything else I'll have to talk to a local farm for some carabao shit.
Member 99.99 posted a successful grow using the homedepot brand steer blend in this thread, he didn't even pasteurize it:
https://www.shroomery.org/forums/showflat.php/Number/28081356#28081356
If this is easier and less suspicious to acquire then use it, I would pasteurize it though to be on the safe side.
Hey, just thought Iโd let you know Iโm on my second flush and the substrate has just barely started to contaminateโฆso thats about 3 weeks in my martha which is about normal to start see contamination
