 gypsum question 
#761230 - 07/20/02 06:22 AM (22 years, 1 month ago) |

my buddy is thinking about using gypsum in his next batch of millet spawn. went to the store today to get the gypsum and now have a few questions about it. most notably, this gypsum is granulated not powdered... so is it the correct stuff. also, it is brown, and the cat told me he thought gypsum was white? will this granular gypsum break down when the cat puts it in the autoclave?
thanks

It?s grey, more or less.
I don?t know if the granular stuff will break down, I guess it would be best to break it into powder.

You can get powdered gypsum from most any homebrew supply store.

Is the glass half-full or half-empty? I say it is both.

Lowes, Home Depot, True Value, Ace Hardware & Garden Supply stores have it a lot cheaper than Home Brew supply places. SixTango

Plaster of Paris, which is dehydrated gypsum, should do the trick too, right?

Hey there,
What does gypsum buy you in this circumstance? I know it is good for helping break up compacted soil and let it absorb more moisture while also providing calcium and sulfur nutrients. Good for use in the garden...
Best regards,

home brew gypsum is polverized, more or less, down to a chemical grade. I've used bagged gypsum, which seemed to keep the rye from sticking, and it was about the consistancy of sand with powder.

adding gypsum to grain when it is autoclaved is said to help keep the grain from sticking together. this allows the grain to break up more easily if one wanted to shake up the jars durring colonization.

I don't think this is relevant to cubensis,but some species (such as Shiitake) have a nutritional requirement for calcium,which gypsum can help supply...

so nobody has tried using plaster of paris (which is dehydrated gypsum)?
i think I'll just keep using it, a little water of crystallisation shouldnt make any difference for our purposes.

Hey there,
Yeah, thanks for the good answer...that would make sense as it is used to break up compacted soils. Those rye berries love to clump up on the bottom in goo, don't they??! 
Best regards,

thats true and it would affect the pH like gypsum would to my understanding.
