Saw this a while back and did a little look into it recycled material, pH neutral, infinitely reusable ( obviously they never had to get it out of coco), no dust and doesn't breakdown. I'll check it out, put it in some stuff maybe, put a dwc together using it.
Been meaning to get some veg started in dwc this year.
Mix a bag of this, with a bag of Turface, and you should have a good medium for hydro growin ! It's funny how Turface hasn't caught on in the weed growin community. Horticulturist have been using it for a long time ! It offers the best of both drainage and moisture retention, is reusable, and PH neutral.
yes, it does float. but lets see if that changes threw some into some water to see. so apparently it does hold air not sure if that's a good thing, should be holding moisture right? or air I guess. Dual purpose. ha! I guess if you wanted to separate the media after use floating kind of works. for cleaning
