But my question is why would you want to shut off the CO2 at night. People that do that save a little CO2 from their pressurized setups, that's all. The plants don't benefit that much from lower CO2 at night.

I haven't noticed much of a difference when I ran CO2 24hrs a day vs. when I ran it only with the lights. I have a solenoid valve on my pressurized setup and I think I'm going to take it off. It's needlessly drawing current because I have it running 24/7. I would say don't worry about it, and if you're still worried about it...you can either shut off the pump, or pull the CO2 line out of the bottle so that CO2 is just offgassing into the air from the bottle.
