Hi all
We don't produce perlite here on any large scale so I cant just go out and buy it but I have seen white balls in the potting soil that I buy. At the time I thought it was styrofoam because it is soft. However it looks like the pictures of perlite that I have seen.
Should perlite be soft like styrofoam or is it hard? I know it would be light but I imagined it to be fairly hard, like pumice.
