5-1-1: OK to substitute granite for perlite?

Good evening everyone. I'm getting ready to mix up some 5-1-1 over the next few days and have a question.

I have fresh pine bark (1/2" and smaller) with a significant amount of pine bark fines (1/8" to dust), so I won't be adding any peat to this new batch of 5-1-1.

My question is, can I substitute granite for the perlite? I have a large bag of Manna Pro Poultry Grit, which is crushed granite, and I'd like to use it in the 5-1-1 mix. I think it would work the same as perlite, but add additional weight to the mix. I don't see any reason not to use granite in the 5-1-1 mix since it's only 1 part of the mix.

Any thoughts on this, either good or bad?

Thanks.

TYG

An increase in bulk density and a slight reduction in water retention are likely to be the only things you'll note if the exchange is volume for volume.

LOL, I was thinking about the same thing. I'm curious as well.
