Helmut79 Well-Known Member Nov 10, 2017 #1 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.

Helmut79 Well-Known Member Nov 10, 2017 #3 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.
