Ok so Im wanting to use Gypsum in my bulk substrate. I know we measure by volume but in reference to gypsum as a whole volume is really imprecise. I recently put my pelletized gypsum in my blender to get to a really fine grade and it took over 4.5 quarts of pelletized gypsum to make 1 quart of fine gypsum, so wtf which one is correct? Please guys lets elaborate on this a little
Ps. I would really like to know what type RR uses......

All of the gypsum I have ever seen at stores is powder (except for drywall of course). I do not think it is that big a deal anyways as you only need a little. I mix about a tablespoon into a gallon of water to soak the rye in. Plus, you do not technically, really need it at all. It helps, sure, but you can noc up straight grains just as easily.

Pelletized gypsum is going to throw off your figures, whether by volume or by weight, as it uses a water-soluable binding agent... It is used for broadcasting via machinery in open field crops, etc...
Just plain powdered gypsum is roughly ~24g per 1/8 cup, iirc...
If you were following Damion5050's Bucket Coir Tek: 650g dry coconut coir ~400g dry course vermiculite Total dry weight: ~1050g 5% of total dry weight equals ~52.5g
So; about a 1/4c of dry gypsum works out well

I thought the proper amount was 5% by volume, this is really imprecise, if you used 5% by volume you should have right around what 3/4 of a quart, which is a big difference from the 1/4 cup

Correct; adding additives by volume is very imprecise... Which is why it is best done by dry weight; which is very precise

I get what your saying but "theoretically" using the standard powdered gypsum, which i believe is what the 5% rule comes from, wouldn't you want to use the volume method? I see what you've done and its pretty smart, but i can't help but think that where missing something. If we do it like your wanting to then thats roughly 1/4 cup, and if we add gypsum @5% by volume then it would be around 2 cups, which is 8 times more. I can't help but wonder If I followed what your recommending, that I might be giving my mushies only and 1/8th of what they could process efficiently. I would really like to know what form of gypsum was used when the original 5% by volume method was deduced.

I use a pint of pelleted gypsum added to Damion5050's coir tek. I have a tub going right now as an experiment with twice that amount (percentage-wise, the recipe is actually cut in half for this tub), but I just spawned it last week so it's still consolidating. I used to grind it up, but don't bother anymore. The 4:1 ratio between pellets vs. powder seems about right to what I remember.

oh well i guess I'm go with 3.666666% by volume of the ground up pelletized gypsum or 3/4 quarts per 20 quarts spawn, damn i was hoping RR would stop by here and break it down.

I don't think he likes being called out just saying. if its powdered our not you could convert how man g/oz/lbs or whatever measurement is appropriate by weight like if you need a cup of powdered is 128 g it should still weigh the same as pellets....

Big_Sexy... I answered your questions (and then some); as well as explained the answer... Yet; you delayed unnecessarily... And then; when you did proceed, you did so incorrectly 
What was the point of even asking to begin with?

I am pretty sure RR uses powdered. And if you haven't noticed almost everything in this hobby is imprecise. Look at a brick of cor. No to are alike, but they still work. Don't worry so much about getting it perfect, just have fun and it will all fall together for you.

In my thread: http://www.shroomery.org/forums/showflat.php/Number/15616235
I asked:
Quote:
Vibration said: I'd like to know if 50g is a good amount to add to my bulk substrate (650g brick of coir + 3 quarts of fine verm + 3,5...4 quarts of water)
I'm asking this, because I have gypsum in 50g packages.
And if you know a good answer, how is that amount of gypsum going to affect the substrate?
And RR responded:
Quote:
RogerRabbit said: Gypsum is used to provide calcium and sulfur, both of which are essential minerals required for good fruit formation. The pH stabilization and non-clumping properties are side benefits, not the main point.
Why 50 grams? Don't buy food-grade gypsum from a brewery supply at 100 times the cost. Get ground gypsum rock for 1% of the price they sell it at brew supply places. I can get 80 pound bags for $8, but it's a lot cheaper by the truckload in bulk. I get it for $117/ton dumped right into my truck from a hopper.
Simply ask any local farmer where he gets bulk gypsum to spread on his fields. He'll give you the industrial scale supplier where you need to be buying from. RR

You should use whatever works best for you. Just try out different amounts such as 50g, 5%, 1/4 cup, and so on. Trust me when I say that you are not going to see much of a difference in using lots of gypsum vs. little gypsum, so its not something you should be worrying this much about to be honest
