What you mean? At the warehouse they run 11-1300 constantly during day time and day time temps are always 71....I don't have a closed system gotta refill my tanks every 4-6 days depending on temp outside and I'd say co2 is everything alot more than what y'all give it credit to be. High co2 and lower temps means the stomatas don't have to open for the plant to breath allowing for tighter more uniformed buds. Higher temps and lower co2 means looser bud due to have to open and breath.so im growing strains like GDP and Purp Haze where i need temps to stay between 70-80 to bring out the colors...How do you guys go about implementing c02 when that normally requires temps to stay on the higher side??
