Those are actually Growstones. It is made out of 100% recycled glass. Zero ph impact, doesn't hold bad bacteria but holds tons of oxygen. I have had great experience with it. I mix it about 50/50 with my coco in the hempy buckets. I fill the entire bottom with the growstones and then do a mix of coco/growstones for the rest. Have had fantastic results with that. They actually pre-package a coco mix with their stones mixed in, but I use a particular brand of coco that has a lot of biologicals and I like to have more control of things because I have issues like thatYo are you using volcanic stone instead of hydroton? I always wanted to try that I use the volcanic stone at the bottom of my coco-coir pots.
totally recommend these...but they do cost more than say perlite, which is an equally amazing option and very, very affordable. Same properties and great performance.
