I understand your saying here that the pellets are the same
base material, but does it work properly in the mix or does
it need to be powdered to be properly distributed in the mix?

The binder in the prills quickly dissolves and the prills break apart, ending up being the same product as the powdered gypsum.

If it didn't work properly, I wouldn't suggest it, or I would at least qualify whatever I said so you could know of any drawbacks in advance.

Thanks. I guess I was just being slow on my interpretation of what you wrote and wanted to make sure I didn't mix up 10 cuft of gritty mix with the wrong stuff in it.
