G'day Michi,

That was the clue I needed.

A Hydroponics supplier in Sydney had it for $5 or $10 per kilo (depending
who answered the phone. :-) I ended up paying $5 for a kilo.

link.

Thanks very much for your help.

Graham.

I looked in the Yellow Pages for hydroponics suppliers. I found one nearby
(Enoggera, Qld) who sold me a kilo for about $6.00.

Cheers,

Michi.
