Stoping Co2 Two Weeks Before Harvest Question!

[3 balls]

No what I am saying there is to try to keep humidity lower in flower due to the risk of fungal pathogens. The main thing with CO2 is the plant will use it if the stomata are open. That creates quite a wide range re RH.

I get it now, I was interpreting optimal as necessary. I'm glad I posted about it and you corrected me. I'll take any advantage I can get to speed up veg! Thanks
