I'm wondering if anyone has used oil-dri instead of perlite for soil aeration and drainage. I had planned to mix 3 parts happy frog to 1 part oil-dri. I did a search and it was mentioned in one post here: https://www.rollitup.org/general-marijuana-growing/308491-soil-question.html, but found little else. I use oil-dri in my cactus mix and it works well, I hate perlite.
