What is the perfect timing for supplementary co2?

Switch on when lights on and switch off when lights off?

.. or should it be switched off a bit later after switching off lights or something along these lines?

Just want to make sure how is best.

I just go with the photocell. Turns on when the lights come on. Is their another level of optimization?

Could keep co2 system on timer too, but I'm just wondering if there might be a benefit from pumping co2 after lights turn off - for example 30 minutes more. Maybe photosynthesis doesn't stop right away. I don't know.

Once the lights go out your plants no longer need CO2 and begin to release it.

So true Cannabis is a C3 plant

memorize this

CO2 + H2O + RuBP → (2) 3-phosphoglycerate

good luck
