First go at homemade bulk sub, could use feedback

hey there, i've had a good amount of success with substrate purchased on the internet, but I want to try my hand at making my own substrate so I will give y'all an outline, maybe you can help if some part of it seems off.
5% coffee grounds 50% horse dung 15% locally sourced organic compost 20% coir 10% wheat straw shredded gypsum added for 10% of total weight potentially oyster shells or hydrated lime for pH
so i am going to mix this stuff up and put it in myco bags, then pasteurize either in a pot or the oven, I haven't decided yet.
any feedback would be much appreciated as I would like a single recipe to use for a variety of compost loving mushrooms. Thanks!

I'd lose the straw and drop coir amount to 10% and add 20% vermiculite instead.
Don't have any experience with organic compost, but think it'll work.

I would do 95% coir a bit of gypsum and i would sterilize it. Or find verm do 80coir 20verm a bit of gypsum and sterilize it

I think the point of his post is to try and experiment with different substrates. I think OP just mainly wants to know if his is ph gunna be off.
But yes, a lot of cultivators use a coir/verm based sub.

sounds like OP wants to make his first home made bulk sub.
doesnt get easier then sterilizing cvg.

cool thanks y'all. The reason I am using these ingredients is because I can get an endless supply locally except for the coir/gypsum. Also given that the FC is going to keep the humidity at 99% I have never used verm, but I suppose I could. The compost is actually not free, but I am getting a lot anyway for a garden in the spring, and it is really good stuff. I think I might use less of it in the ratio though, it gets very muddy when wet. thanks for the feedback!

Fruiting chamber with 99% humidity sounds like a shit design.
Evaporation is a main pinning trigger.
Surface humidity should be 90-99%. The space less than an inch above the substrate.
The air in the fruiting chamber itself should be 50-80 and fluctuate
Evaporation is a major pinning trigger
Saturation humidity leads to waterlogging and stunted growth if any

woah chill, Yes i was referring to surface humidity, Obviously i'm not running a sprinkler in my FC.

Tira, have you always used vermiculite, or have you done it without and find it works better with it? Just curious because the only time I did use verm I didn't notice a real difference except longer colonization time, which honestly was probably incidental.

I've almost always used it, only time I didn't use it was with some bulghur flour/hpoo cakes and that really didn't turn out really well (very small fruits)
Actually this is what I'm referring to when I'm preparing substrate, a 7 year old post, so I wouldn't stay in the way of anyone who wants to experiment with substrates with and without verm .)

hey thanks, thats a helpful link. I have a question that I think I already know the answer to, but here it goes. I have broken up the horse poo I got from a nearby equestrian center, and set it out to dry, It has been a little cold and rainy, so It isn't drying very rapidly. Anyways, today I noticed cobweb mold growing on it, and I tried to remove the parts that had a lot of growth, but I know how it works with that, it is probably already growing in it, just not producing spores yet. I realize the purpose of pasteurizing is to kill the microbes that are not beneficial, but am I taking a risk by using this poo anyways? Thanks.

You said you set it out to dry, are we talking about fresh hpoo here?
Because we need horse poo to be free of ammonia and that happens after it gets rained on a few times and dry, so all the ammonia is leeched.
I recently fucked up a big monotub by making the mistake of freshly collected hpoo, though all the pellets were dry both inside and outside, they still had ammonia in them so mycelium didn't like the substrate very much.
And using something that has mold in it is not a good idea, no. Especially when you're not sterilizing, just pasteurizing, I wouldn't take the chances.

Id only be concerned with cobweb in a jar. But it could also be an indicator it needs to be leeched longer. Best of luck

 could skip the lime we normally only use it for pure straw sus or casing layers

Looks like a shroom-tastic bulk recipe. Oyster shells won't do much for PH, but some people put them in there to fluff things up a bit. They are really dirty, so rinse them well if you decide to use them.

This would be a good idea, since you are new to bulk substrates. Things like coffee and horse manure require you to have your pasteurization technique on point to be successful. Using a simple recipe like the one above would be good practice to get the moisture content and consistency right first, and then move on from there.

Thanks for the feedback! First off yes it is fresh horse poo, I'm aware of the ammonia issue, I changed the way i set it out, so we shall see what happens. I am not particularly worried about the mold. If I mess up pasteurizing then yes it will be all bad, but do not fear! I can do it. I appreciate the suggestion about a simpler tried and true recipe, in light of that I have opted for this: 40% poo 10% coffee 30% coir 20% vermiculite With gypsum and oyster shells.

PH isn't really a concern for bulk subs anyway because they get fully colonized
