This CO₂ controller by Inkbird maintains the CO₂ level of your mushroom grow tent within a user-specified range. It has two separate "WORK" functions. "WORK 1" is for CO₂ generation and it not useful for mushroom-related applications. This function is useful for plant cultivation, but not for mushroom cultivation. "WORK 2" is for CO₂ elimination and is the function mushroom growers will utilize to expel CO2 from their grow tent via an exhaust fan. This CO2 controller can turn on your mushroom grow tent's exhaust fan when CO₂ levels inside the tent exceed a specified limit.
