Ona Control Duct - Large

Special piece designed to couple to the tubes of your extraction system, designed to control odors from our indoor marijuana growing box .

This metal tube is manufactured as an accessory to the air output system in our crop, to work together with the odor neutralizer Ona Block.

In its inside, it has a grid cylindrical shaped connected to a lateral opening of the tube, so that we can put inside three Ona Blocks. And when the flow of air loaded with odor passes through the mentioned grid, the blocks will combat the aroma of marijuana, destroying it completely.

Includes duct + 3 Ona Blocks.
