Greetings fellow mushroom enthusiasts,

What is the best CMC (cow manure compost) to use for my bulk grow?

I called my local grow shops and they both carry the same brand of CMC: Bu's Blend Biodynamic Compost: Organic and GMO-Free Soil Amendment.

Ingredients: Organic dairy cow manure, straw, wood chips, and biodynamic concentrations of yarrow, chamomile, valerian, stinging nettle, dandelion and oak bark. 

Is this good to go? Should I look for a different brand? What do you use?

Any that doesn't contain a fungicide.

I use Black Cow from Lowe's or Home Depot.

I’ve only ever done coir substrates....it’s cheap and forgiving..I’ve heard any manure compost is better yields though I have some experimenting to do... working my way up to it

Compost is pretty much compost. Just as @MagicalCriminal said none with fungicides. Compost is organic by nature. Get what you’re comfortable with. If you want to pay a bunch for a bag with words on it, go for it. You’ll have the same exact results as if you got free compost which is still organic. Do what works for you.

It is just compost that at some time was manure. It is not manure anymore. It’s just low nutrient dirt once it has been composted, for lack of a better term. Much better than coir, but it is good to add coir for its water retaining properties. Saves expensive vermiculite.

      Bought different trash bags and 12 small containers today.   Couldn't find any that had flat bottoms.   They all seem to have that middle raised part to them.    Guess I'll sit down today and see if I can put some colonized grain spawn to substrate without any tams.    It's time to see if the Jalisco will do something.   Wish me luck.

      @SonshynI think it was my own brain fart.  1:6 or possibly 8 uses a lot of sub.  @El_Piraña I will read up on the tek. I can PC almost 42 quarts at a time, but pasteurizing does have its benefits.

      I almost always pasteurize my substrate instead of sterilize. When I started pasteurizing, I would put the sub in quart jars and use my PC without the lid. But that still limited me to 7 qt at a time, maybe 3-4 more quarts if I used a second pot at the same time. I was running into the same problem, couldn’t keep up with making enough sub.  I changed to using large disposable lasagna pans. I would fill up four of those at a time, seal with aluminum foil and put them in the oven. I can’t recall how many qts in each pan, I don’t have my notes with me.  I did get more evaporation with this method so I had to start with slightly extra water so that the end result was field capacity.

      Maybe use the oven instead of the pc ?

      @Moonphasenext ones will be better. So far the first 3 tubs are doing ok. All 3 look like this. I folded the plastic down to help keep the edges from evaping to fast, but left it up enough for some fresh air.  Going to open it up in next day or so. Fingers crossed for tam free even pinset.
