Sweet I have Azomite and Oyster shells and the Bulk substrate has gypsum in it. Btw the amount of bulk substrate will be 4lbs a long with 2lbs grain spawn so how much then would it be? I do have Dolomite limeYou should be ok, that's how they come typically. Calcium is a good component to add. I add lime/gypsum (1:1) and azomite in a small amount. Coffee is good for spawn but not the fruiting sub.
