I had an idea recently that I thought was pretty good, so I cant be the first person to have ever thought of this.
Basically I think using black glass marbles instead of hydroton, but before I go and try it I would like to throw the idea out there for feed back. Here is my reasoning.
1. No dust. leads to cleaner roots less washing time.
2. reusable, wash in a bucket of soap and hydrogen peroxide
3. hydroton factory in Germany closed.
4. not porous so it does not soak up anything at all.
5.stronger doesnt brake apart so easy.
6. bulk marbles are pretty cheap. $48.00, 2750 marbles.
