In my personal experience, I have found that the simpler you can make it - the better.

I use a pressurized system with a 5 lb bottle, Milwaukee reg and a glass diffuser. I have a timer set for the Co2 to come on 30 minutes before the lights do and shut off when the lights shut off. Photoperiod is 10 hours a day - 5 on, 2 off, 5 on. I run at about 130 - 140 bpm, with a Co2 ppm of 24 - 28.

pH controller seems like overkill to me (from what I have read). But the great thing about this hobby is that there are many ways to get basically the same result and what works well for some, may not work as well for others.

I agree - experiment and find what is best for you.
