To keep your carbon filter in top working order, it’s important to regulate the environment in your grow space correctly. Operating in an area where humidity is above 70% will reduce the filter’s lifespan and ability to function.

This can be a particular issue during the propagation and vegetative stages when humidity is at its highest. In those circumstances, make sure to keep humidity below 70% so your filter stays happy and your plants thrive.

Many growers have two filters. One for use during the veg period (high humidity). And a second that they only install during flower when the carbon filter is most needed.

And because it’s not used in highly humid environments, the lifespan of your carbon filter will improve and become more reliable.
