Thanks a lot Hoppy. Will read up on that and add to the article. I agree about the low light comment, but the problem is that most of us don't have PAR meters, and probably 80-90% of PT enthusiasts probably stop at the WPG type rules and CO2 levels when determining what plants to attempt growing.
That's why I'm a bit hesitant to compile a list myself. Perhaps I'll just add some of the no brainer low light plants for now.
