Has anyone ever used these in a soil mix, or even as a hydro medium? They are made from recycled glass bottles, and appear to be a more enviromently sound replacement for perlite, pumice, etc. The manufactuer claims they are reusable with minimal break down over several uses. The air/water ratio is much higher than perlite. I couldn't find any information and ph levels, but i assume being they are 97-99% glass ph is neutral. Anyway going to do some more looking, but i thought i would share with the community and see if anyone knows more about this product.
