When everything in your grow is dialed in and want to supplement CO2, it’s about consistency. You need a CO2 controller to make any difference. Without a way to control the levels, you’re wasting time and money. CO2 boosts are not helpful. Plants produce a certain number of stomata on a leaf depending on CO2 levels to be efficient. If CO2 levels are low, the plant will produce more stomata per leaf. If CO2 levels are high, they’ll produce fewer stomata per leaf. Fluctuating CO2 levels throughout the day without consistency confuses the plant.
