DAP Bondex Plaster of Paris
    #11305541 -

I was at the hardware store and saw this box of PoP. It says that it contains Calcium Sulfate, Calcium Carbonate and silica. If I need to I will get some drywall and use it, but if a person were to use this when prepping grain jars before PCing would it be beneficial because of the calcium carbonate? I mean would the calcium carbonate help keep your jars free of contams by raising the PH in the jar?

calcium carb should only be used for sub and casings where needed

Mushroom mycelium colonizes acidic substrate faster than non-acidic substrate.

However molds prefer acidic as well. Once the bulk substrate is colonized, it's not much of a concern. I do not worry about pH unless I'm using a casing. IMHO

deathblade said:
Calcium Sulfate, Calcium Carbonate and silica.


Add a pinch. That first one is gypsum. The others won't matter either way to a grain jar.
Don't add so much that it gets weird.

The ingredients list has the calcium carb and the silica listed. I am not mixing this myself. I wasnt gonna add much just a bit like RR shows in the video. I think that and experiment might be needed. Just to see the dif side by side.

I should have mentioned that I wouldnt be adding the PoP out of the box. I have mixed it with water and let it harden and dry. I am going to crush it and then add it like gypsum. I was told that it chemically changes after it get rehydrated.

Oh, you don't have to do all that. It's going to get hydrated anyway. Just sprinkle a pinch in teh jar.
