For Sale Hydroton - medium flat rate box

[thez_yo]

I have a pile of hydroton I bought and never used and it's a shame to just dump it because it's a bit expensive. I've got 2 medium flat rate boxes of it for $38 each including s/h. Please leave a message here if you want it, then PM me your address and I'll give you my paypal.

What exactly is hydroton?
