I know this is an old thread but I like the topic. I use rice hulls in a few of my cacti mixes, they don’t stay wet enough to rot. A few other things I use from the feed store are Safe-T-Sorb and Oyster Shell. Crushed Oystershells I use as an aggregate in soilless mixtures and as a source of calcium. Gotta be careful with the PH though. And Safe-T-Sorb is just calcined clay which is a hugely common soil additive for bonsai. I use both for cacti mixes. I’ve been toying with the idea of using the calcined clay in place of pumice which I try to use in place of perlite but I need to look into it more since I’m not sure it would function as a 1:1 swap.
