No hydroponics stores in Tassie ? Do they just
grow their smoking tomatos out in the open down
there :P

Don't worry - I wont make any Tasmanian jokes.
Here in Brissy we normally are too busy making
Ipswich jokes.

You can get buy without H202 for the CuCl

start it up.

It was that stuff they call "40%" which is some
measure of volume gas or something. It's realy
27% or something similar from what other posters
have said.
