20 yrs ago the guy who taught me to grow ( may he rest in peace) had me set my temps at 72 when lights are on and 68 when off and he had me run a sealed room with co2. The thing is I never looked into it and after all these years I found out to utilize c02 your temps need to be at 80 when lights are on or hotter. So anyone know if what I'm reading is correct? Makes me sick to think after buying 10,000 tanks of co2 it was for nothing. I would love to hear your opinion on this. Thanks
