I was concerned about the CO2 also - I'm in the process of getting a 20 lb CO2 tube and a regulator - coming soon. As for what you're saying about root balls and my pots - I'm confused. I'm not sure if I'm reading what you're saying right or if I just don't have any idea what you're talking about. =) If you could expand on your topic before so I understand better I'd really appreciate it.

Also, anything about the white dots/marks?

Thanks again!
