Ended up buying a bag of it at NAPA store 1200 miles away from home on a vacation mainly because I needed a set of new windshield wipers for my car. I had forgotten about it till I walked in the store and saw them sitting there by the door. Funny how that works out.
Anyway, has any more of y'all tried it lately and see any difference compared to Turface, expanded shale, and zeolite? I have all of these available so I suppose I could try them with bald cypress seedlings that I grew from seeds and see how that goes.
