I may have the opportunity to get some pumice local to me, which is tough to come by…the catch is it is 2.0-3.4mm grade. That’s like 1/8-3/16”. Is that too small, the perlite in most mixes isn’t much bigger? If using something like that would you use more or less than using regular 1/4-3/8” pumice. Or would it not really work regardless.
