Why do we start co2 an hour before light ?

Interesting conversation, I leave the CO2 on 24/7. I do not use a bubble counter or a ph controller on two different set up (56 & 75 gal).
Basically I use the info Diana pointed out in her post about morning CO2 levels. I have adjusted so the little phishies ver so slowly adjust a NV55

Dang phone.


Anyway I have it adjusted so that just before lights come my drop checker is about the close as you can get to yellow and still has a tad of green. As the day progresses it gets greener and greener.i leave it this way for the life of the CO2 tank. No power needed :-)

Some plants use a 'fast start' strategy to out-compete other plants. They can photosynthesize in the early dawn when the light level is still low. It is for these plants that we want the CO2 level to be up there pretty good as soon as the light comes on.

In nature the things that provide CO2 go on 24/7, so the effect overnight is rising CO2. The level is highest in the morning as the sun rises.

Marry me.
