I got this perlite as the bag of coarse perlite I had ordered prior to was too coarse. As I need an additional propagation box, I really needed to source appropriate perlite and this seemed to be the one. It is over all what I was looking for size wise. Small enough for the prop box but big enough to add the bulk and coarseness I need from perlite in my aroid and other tropical plant substrate mixes. I do wish it didn’t contain the amount of perlite crumbles and dust it does. But am starting to wonder if that’s not just the new norm? Sigh.
