I have a small room of GG4 that wasn’t supplemented with any CO2 through veg (technical issues with the fuzzy logic). I had to flip them and I was curious if it’s too late to introduce CO2 to their environment? All of my rooms are sealed.

You are good to run CO2, @ok.alternative.ag. Your plants will be happy. You can use CO2 throughout the grow process

Understood. We do run CO2, I’ve just never implemented it so late in the process. Didn’t know if there would be any issues I’m not aware of. Thanks @Growernick.
