ONA Block: solid odor absorber
Since 1995, original solid odor absorbers have been manufactured in Canada. Why mask an odor when you can eliminate it outright, right? Each of the six fresh and fragrant variants is ideal for placing in small rooms and grow boxes. And not only there!

Having a grow tent equipped with proper ventilation with a carbon filter usually does not guarantee a completely 100% absence of unwanted odors. Especially during periods of increased humidity associated with the late flowering phase and fruit ripening, it is common to notice a slight but undesirable smell or residual aroma wafting from the grow space.
Forget endless airing out or masking odors with products that don't pay off. A smart solution is these neutralizers of organic and inorganic odors based on plant terpenes, which, among other things, have antiseptic and antibacterial effects!
By destroying odor molecules rather than masking them in the grow space, the oxygen saturation of the grow space is also increased, which of course benefits the plants.
ONA Block solid odor absorbers are also considerably more practical than the gel ones. Why?
- Solid structure (see below).
- More compact packaging. Thanks to smaller dimensions the containers (only 7.5 x 7.5 cm) are ideal not only for grow spaces but also for small cabinets, for cars or, for example, backpacks with used sportswear or laundry baskets with dirty clothes. The uses of ONA Block in everyday life are practically limitless.
- Attachment for placement into an air duct or a dispenser will amplify the final effect.

Using ONA Block in practice:
- The first option is to unscrew the lid, or make several holes in it, and let the neutralizer act freely in the chosen space, for example in a growbox. The solid structure of the solid absorbers does not prevent removing them from the container. You can place the solid contents, for example, on the lid, which increases its effect when placed freely in the space. Placement near a fan is also recommended.
- For an even greater effect you can use the special Ona Block Dispenser. Then simply turn on the fan.
- The third option is to use a neutralizer attachment. How to do it?
- Depending on the diameter of the air duct in the growbox, choose the appropriate diameter of the ONA Odour Control Duct.
- Then place it into the air duct anywhere downstream of the extraction fan, following the direction of airflow.
- The attachment has a little door which you open and insert the contents of the ONA Block package into the opening. Then simply close the door again.
- The air leaving the grow space will be odor-free and pleasantly scented, for example like freshly laundered clothes.
