I was so intrigued by this post that I actually read the entire thing. (Managed to listen to 3 CDs also lol.) First I would like to say nice plants all around everyone. (Especially impressed by the CFL user.)
Secondly, I've been wanting to switch over to BP from soil (I know, I read the soil bashing in the earlier posts; not trying to hijack and talk about soil.

), and I am also very interested in joining your Bubbleheads group (That is when I've learned enough to turn around and teach.) I really like/respect what you guys are trying to do by trying to teach everyone that's intrested in your grow techniques. I also like the fact that you guys take the time to entertain most everyones questions no matter how stupid they sometimes are.
That being said I'd like to start my switch by just trying one plant in a homemade 3gal bubbler. I haven't begun yet because I don't have a PPM meter. How could I manage with just a pH meter for a grow or two? I was also wondering how big of an air pump I'd need and what kind of air stones to buy for the single-plant setup. Can you point me in the direction of some more reading for a noob to bubbleponics?
