Available in a number of different diameters to cater for your hydroponics set up: 4, 6, 8, 10 & 12 inch ducts.

ONA Odour Control Ducting + ONA Blocks

Most grow rooms, when in use, will produce some unwanted smells, this happens when organics, compost or water produce natural gases.

It's always best to keep your grow room clean and the same goes for the contained air too. We recommend running extraction system 24/7 for just such a reason.

The ONA Odour Control Duct is the perfect solution, simply attach in the ducting run using the corresponding solid or flexible ducting and fill the mesh tube with an opened ONA Block, any volatile/odourous molecules carried along the way will be effectively neutralised.

Access is easy through a neoprene lined trap door via quick release catches. The ONA Odour Control Duct remains completely air tight when closed and attached with clips or clamps.

For best results we recommend removing the ONA blocks from their plastic pots. This allows for maximum air contact but will shorten the life of your ONA Block.

The 4, 5 and 6 inch models house 1 ONA Block, the 8 inch houses 2 with the 10 and 12 inch models housing up to 3 ONA Blocks.
