Printed out that article, I will spend some time with it this weekend.

Heh. I suppose it is!

Looking into it now. I can get a 20lb tank for $150 (CAD). Refills are 
$32 (CAD). Not too bad. Now all I need is the fiddly bits: regulator, 
needle valve, bubble counter...

-sigh- Okaaay. I'll test it.

The light is probably not quite as high as it would be with most 175w MH 
setups. The lamp I am using came off a navy ship. The refelctor was 
designed for a bigger bulb and hasn't got exactly a mirror finish. So I 
am probably losing more light to heat than other MH users. But it's got 
character! And it is a huge improvement over the old 2x32w fluorescent 
canopy I had. It needed a massage every morning before the tubes would 
strike.

Because I'm not too bright, probably!


Thanks Tom.
