PS. I use hydroton brand, and don't know if there is much difference between brands. Many grow stores will only stock Hydroton, at least in my area. I suspect that they're all pretty much the same, but there are many differences in clay. Hmmm...

You see, the deal is I think I have trouble even saying the word "rockwool". Maybe I need professional help.
