Ideally we recommend you replace the carbon filter every grow. You can think of each carbon pellet as being a planet with craters. The smell is removed by getting caught in those craters, but over time they fill up and no longer do their job. ’
Fanatic - Our current filters remove a majority of the smell, however we have new ones coming in which should completely eliminate it. We will have more information in a few weeks. In terms of the light emissions, we do not currently have plans to cover the fluid glass, however I’m sure you can rig something up!
