ONA Odour Control Ducts 6"

Over the duration of a crop, your plants will naturally create some unpleasant smells - they're living things after all! To combat this issue you should try and do everything that is possible to promote freshness in your grow room, which includes running regularly extracted air through an ONA Odour Control Duct. By simply placing one of these useful units between two sections of ducting and filling the mesh metal internal tube with an opened ONA Block, any odourous molecules carried along the way will be effectively neutralised. The access port is easy to open up via quick release catches if you need to add/remove ONA Blocks and also features a rubber seal to ensure it remains completely air tight when closed shut.
