Acoustic Duct Fans are used to move air to-and-from your grow area.
There are many reasons why this is such a necessity.
Plants depend on CO2 as an essential part of the process of photosynthesis.
As carbon dioxide is used by plants and levels in the atmosphere become depleted, air in the room needs to be replaced.
If stale air isn’t moved from the grow area, moisture quickly builds, raising humidity and triggering problems with mould and rot.
Duct fans also tend to be used in conjunction with carbon filters to remove unwanted smells,
as air is drawn through layers of charcoal and cleaned to remove odours before it reaches its exit point
