TUMS in bulk substrate rye jars to maunre/straw hautla

i was wondering if you could ad crushed up tums to bulk substrate for the calcium carbonate
just wondering how many mg of calcium carbonate i need.
i plan on spawning with a 1/5 ratio. that is 1 pint jar of colonized cakes to 5 pints of a mix of 50/50 poo and straw.
so for every 1 pint jar and 5 pints of spawn how many tums should i add considering they each have 1000mg of calcium carbonate.

None, because you don't lime substrates. Mushroom mycelium prefers an acidic substrate. Add gypsum at 5% or so by volume to supply calcium and sulfur. RR

i have no idea... way to be creative though!
if you want calcium carbonate, blackboard chalk is a good bet too

so a 1 pint jar of gypsum would be enough for 20 pint jars cakes and 100 pints of spawn RR?

You can add a small amount of gypsum to cakes. About 1 tablespoon for five cakes, Don't even ask about pint cakes. You should use HALF pint jars for cakes.
For 100 pints of bulk substrate, five pints of gypsum would be 5%. RR

why are half pints superior for cakes?
i ran half pints previously
but im running 20 pint jar and theyre all doing fine
i also dont care about 100 pints i care about 20 so im assuming to 20 jars 1 pint will be approximately enough
also note your math is always flawed
5 pints jars isnt 5% you have to use 95 pint jars and 5 pint jars
to achieve a 5%of total soultion
5/105 doesnt = 5%

i'm pretty sure 5% of 100 is 5, he isnt talking about ratios at all
so stfu
also, pints have been known to stall sometimes

Because of the time it takes to completly colonize the jars is longer thus giving more time for contams to take hold, cake could dry up, or the whole thing could just stall and go no further. Use half pints and you dont have as many chances of this happening. Good luck with them and hopefully you wont have many problems with the pints. Peace.

it's not really important, but he's right. RR's math is off by a little bit. If you have 100 pints of sub and then add 5 pints of gypsum, you have 5/105, which is 4.7%... not an important difference but a difference no less. To get exactly 5%, use 95 and 5

The bulk substrate is the total product that you fruit mushrooms in. Therefore, the gypsum is included in that total. The math is correct. The above would represent 95 pints of compost/manure, etc., and 5 pints of gypsum.
Besides, you can use up to ten percent gypsum. Anywhere from 5% to 10%, but I've found little benefit above 5% with most substrates. RR
