Peat/verm/gypsum help fast!!
    #510649 - 01/05/02 01:32 AM (14 years, 10 months ago)

I need to know how to prepare a peat/verm/gypsum casing.

I have all supplies. I have 9 cakes that need casing. I will be leaving for a couple days and would like to get this going before I leave.

Thanks for the help!

You want to use lime(Calcium Carbonate, CaCO3), not gypsum in the casing layer. Lime keeps the pH neutral. Use 10% by dry weight lime to peat. For example, if you have 100 grams of dry peat moss, add 10 grams of lime to it.
Since you're adding vermiculite, add the buffer to the peat and then mix 50% peat/lime mixture to 50% vermiculite.

Josh wanted me to ask this, he's at soccer practice and called me on a cell phone! Because his casing is in the oven as we speak, it will be pasturized at 2-2 1/2 hours by the time he gets home.

Does this casing mix sound good:
5 cups vermiculite
5 cups peat moss
1/2 cup gypsn
1/2 cup ground oyster shell

I personally wouldn't add the gypsum. It's not necessary and I can't see how it would do anything, since it's used to stop grain from clumping(at least in mycology). In order to get a 10% concentration of CaCO3, you would add 1 cup oyster shell to the 10 cups vermiculite/peat moss mixture.

I have no idea where to get hydrated lime, oyster shell A or peat moss for that matter. I have been casing with compost/manure and vermeculite. I figured since they grow on cow shit, use cow shit. But I am interested in trying it out.
