Anyone used Gardner & Bloome Perlite before?

Saw them at my local nursery. It says natural and organic, whatever that means.

Are this safe? HELP!!!!

here's the break down of the material

Perlite is about as inorganic as it gets. ......

From the label, it looks completely inert. Just pure perlite. You just have to be wary of the ones that add fertilizers........why some companies do this, I'll never know.

Awesome, I shall keep them.

It's never made sense to me either. If you understand even the basic principles of CEC, you'll realize that it's pointless. Perlite is physiologically and chemically incapable of holding onto fertilizer!!
