Pumice - Large Grain - 2 Quart (PM142-2)

Definitely not Large Grain but will most likely get the job done. The pumice is more on the small side or small/medium. Lots of dust but not completely avoidable when dealing with pumice.UPDATE TO THIS REVIEW: I have been using this for over a month now with my plants and definitely will not purchase again. The pumice is not porous enough to do anything other than be decorative. The majority of my plants I used this with now have root rot and I am rushing to find a substitution to make them healthy again.

I like this to mix with orchid bark. It lets them breathe.
