Ozone generators are a powerful way to eliminate odors in your grow area. Precautions must be taken when working with ozone to eradicate odors, as ozone is a lung irritant and can be harmful if inhaled. The best solution to applying ozone is to ensure that the grow room is no …occupied while the generator is active, ensure that ventilation is functioning properly and is removing ozone after it is created, and that the grow room is not opened or entered for at least an hour after ozone generation ceases.
