Lights on longer or CO2 on longer?

[FSEMTB2]

What is the normal time range for CO2 to be on during the day? And should the lights come on first or go off after CO2?

Thanks

I start my CO2 1/2 hour before the lights come on and turn it off with the lights.

Hopefully you are talking about Co2, not the lights Maxwell

I use a controller, it turns on when it needs it (and I didn't accidentally unplug it)

I run the CO2 about 30min before the lights come on, and about an hour after they turn off. I've heard that plants will continue to grow at near lighted-pace after lights out and wanted to give a buffer afterwards to prevent a CO2 deficiency. Don't know how much truth is to the theory, but it can't hurt IMO.
