I've tested on a small culture and had amazingly accellerated growth rate when I got it adjusted right. Running constant almost always caused a crash as ph would bounce at lights out so I found best to use a solenoid and run only with lights on.
CO2 injection on my main culture rack is my next project (time and $$ providing). You have to be careful though, with increased growth rate you have to be on top of your splits otherwise the culture will eventually kill itself off as other nutrients dissapear. Without CO2 I typically run an 8-10 day split time with it I was around 3-5 days. It makes for a lot of extra work that could prove disasterous should you forget!
