ACTIVATED CARBON FILTERS / ANTI ODOURS
Activated carbon filters or anti-odor systems are necessary only in indoor plant crops where the odors given off by the plants are really very strong.
The carbon filter is always connected to an air extractor and both must be of the same power, the air extractor is in charge of evacuating heat and odor neutralized air to be expelled outside the crop.
There are also other types of odor neutralizers for indoor crops, such as Neutralizing Gels.
